CROSS-REFERENCE TO RELATED APPLICATIONS
[0001] This application claims priority of U.S. Provisional Application Ser. No. 61/747,402, filed Dec. 31, 2012, and U.S. Provisional Application Ser. No. 61/829,125, filed May 30, 2013. The contents of the prior applications are incorporated herein by reference in their entirety.
TECHNICAL FIELD
[0002] This invention relates to methods for biosynthesizing one or more of pimelic acid, 7-aminoheptanoic acid, 7-hydroxyheptanoic acid, heptamethylenediamine and 1,7-heptanediol (hereafter "C7 building blocks") using one or more isolated enzymes such as synthetases, dehydrogenases, reductases, dehydratases, thioesterases, monooxygenases, or .omega.-transaminases or using recombinant host cells expressing one or more such enzymes.
BACKGROUND
[0003] Nylons are polyamides which are generally synthesized by the condensation polymerisation of a diamine with a dicarboxylic acid. Similarly, Nylons may be produced by the condensation polymerisation of lactams. A ubiquitous nylon is Nylon 6,6, which is produced by reaction of hexamethylenediamine (HMD) and adipic acid. Nylon 6 can be produced by a ring opening polymerisation of caprolactam (Anton & Baird, Polyamides Fibers, Encyclopedia of Polymer Science and Technology, 2001).
[0004] Nylon 7 and Nylon 7,7 represent novel polyamides with value-added characteristics compared to Nylon 6 and Nylon 6,6. Nylon 7 is produced by polymerisation of 7-aminoheptanoic acid, whereas Nylon 7,7 is produced by condensation polymerisation of pimelic acid and heptamethylenediamine. No economically viable petrochemical routes exist to producing the monomers for Nylon 7 and Nylon 7,7.
[0005] Given no economically viable petrochemical monomer feedstocks; biotechnology offers an alternative approach via biocatalysis. Biocatalysis is the use of biological catalysts, such as enzymes, to perform biochemical transformations of organic compounds.
[0006] Both bioderived feedstocks and petrochemical feedstocks are viable starting materials for the biocatalysis processes.
[0007] Accordingly, against this background, it is clear that there is a need for sustainable methods for producing one or more of pimelic acid, 7-hydroxyheptanoate, 7-aminoheptanoate, heptamethylenediamine and 1,7-heptanediol (hereafter "C7 building blocks") wherein the methods are biocatalyst based.
[0008] However, no wild-type prokaryote or eukaryote naturally overproduces or excretes such C7 building blocks to the extracellular environment. Nevertheless, the metabolism of pimelic acid has been reported.
[0009] The dicarboxylic acid, pimelic acid, is converted efficiently as a carbon source by a number of bacteria and yeasts via .beta.-oxidation into central metabolites. .beta.-oxidation of Coenzyme A (CoA) activated pimelate to CoA activated 3-oxopimelate facilitates further catabolism via, for example, pathways associated with aromatic substrate degradation. The catabolism of 3-oxopimeloyl-CoA to acetyl-CoA and glutaryl-CoA by several bacteria has been characterized comprehensively (Harwood and Parales, Annual Review of Microbiology, 1996, 50:553-590).
[0010] The optimality principle states that microorganisms regulate their biochemical networks to support maximum biomass growth. Beyond the need for expressing heterologous pathways in a host organism, directing carbon flux towards C7 building blocks that serve as carbon sources rather than as biomass growth constituents, contradicts the optimality principle. For example, transferring the 1-butanol pathway from Clostridium species into other production strains has often fallen short by an order of magnitude compared to the production performance of native producers (Shen et al., Appl. Environ. Microbiol., 2011, 77(9):2905-2915).
[0011] The efficient synthesis of the seven carbon aliphatic backbone precursor is a key consideration in synthesizing one or more C7 building blocks prior to forming terminal functional groups, such as carboxyl, amine or hydroxyl groups, on the C7 aliphatic backbone.
SUMMARY
[0012] This document is based at least in part on the discovery that it is possible to construct biochemical pathways for producing a seven carbon chain aliphatic backbone precursor such as pimeloyl-[acp] or heptanoate, in which one or two functional groups, i.e., carboxyl, amine or hydroxyl, can be formed, leading to the synthesis of one or more of pimelic acid, 7-hydroxyheptanoate, 7-aminoheptanoate, heptamethylenediamine, and 1,7-heptanediol (hereafter "C7 building blocks). Pimelic acid and pimilate, 7-hydroxyheptanoic acid and 7-hydroxyheptanoate, and 7-aminoheptanoic and 7-aminoheptanoate are used interchangeably herein to refer to the compound in any of its neutral or ionized forms, including any salt forms thereof. It is understood by those skilled in the art that the specific form will depend on pH. These pathways, metabolic engineering and cultivation strategies described herein rely on the fatty acid synthesis enzymes or homologs thereof and the cytochrome P450 encoded by bioI from microorganisms such as Bacillus subtilis. BioI is a monooxgenase in the cytochrome P450 CYP107H family.
[0013] In the face of the optimality principle, it has surprisingly been discovered that appropriate non-natural pathways, feedstocks, host microorganisms, attenuation strategies to the host's biochemical network and cultivation strategies may be combined to efficiently produce one or more C7 building blocks.
[0014] In some embodiments, the C7 aliphatic backbone for conversion to a C7 building block can be formed from a long chain acyl-[acp] such as tetradecanoyl-[acp], which is produced in fatty acid synthesis by a monooxgenase encoded by BioI. See FIG. 1.
[0015] In some embodiments, a terminal carboxyl group can be enzymatically formed using a thioesterase, an aldehyde dehydrogenase, a 7-oxoheptanoate dehydrogenase, or a 6-oxohexanoate dehydrogenase. See FIG. 2.
[0016] In some embodiments, a terminal amine group can be enzymatically formed using a .omega.-transaminase or a deacetylase. See FIG. 3 and FIG. 4.
[0017] In some embodiments, a terminal hydroxyl group can be enzymatically formed using a monooxygenase or an alcohol dehydrogenase. See FIG. 5 and FIG. 6.
[0018] In one aspect, this document features a method for biosynthesizing a product selected from the group consisting of pimelic acid, 7-aminoheptanoic acid, 7-hydroxyheptanoic acid, heptamethylenediamine and 1,7-heptanediol. The method includes enzymatically synthesizing two seven carbon chain aliphatic backbones from a long chain acyl-[acp] intermediate and enzymatically forming one or two terminal functional groups selected from the group consisting of carboxyl, amine, and hydroxyl groups in one or both of the backbones, thereby forming the product. The seven carbon chain aliphatic backbone can be pimeloyl-[acp] and heptanoate. Pimeloyl-[acp] and heptanoate can be enzymatically synthesized from acetyl-CoA and malonyl-CoA via fatty acid synthesis and the oxidative cleavage of a long chain acyl-[acp] intermediate by a monooxgenase encoded by BioI.
[0019] The two terminal functional groups can be the same (e.g., amine or hydroxyl) or can be different (e.g., a terminal amine and a terminal carboxyl group; or a terminal hydroxyl group and a terminal carboxyl group).
[0020] A .omega.-transaminase or a deacetylase can enzymatically form an amine group. The .omega.-transaminase can have at least 70% sequence identity to any one of the amino acid sequences set forth in SEQ ID NO. 8-13.
[0021] A 6-hydroxyhexanoate dehydrogenase, a 5-hydroxypentanoate dehydrogenase, a 4-hydroxybutyrate dehydratase, an alcohol dehydrogenase, or a monooxygenase can enzymatically form a hydroxyl group. A monooxygenase can have at least 70% sequence identity to any one of the amino acid sequences set forth in SEQ ID NO: 14-16.
[0022] A thioesterase, an aldehyde dehydrogenase, a 7-oxoheptanoate dehydrogenase, a 6-oxohexanoate dehydrogenase, a CoA-transferase (e.g. a glutaconate CoA transferase), or a reversible CoA-ligase (e.g., a reversible succinate-CoA ligase) can enzymatically forms a terminal carboxyl group. The thioesterase can have at least 70% sequence identity to the amino acid sequence set forth in SEQ ID NO: 1.
[0023] A carboxylate reductase and a phosphopantetheinyl transferase can form a terminal aldehyde group as an intermediate in forming the product. The carboxylate reductase can have at least 70% sequence identity to any one of the amino acid sequences set forth in SEQ ID NO. 2-7.
[0024] Any of the methods can be performed in a recombinant host by fermentation. The host can be subjected to a cultivation strategy under aerobic or micro-aerobic cultivation conditions. The host can be cultured under conditions of nutrient limitation. The host can be retained using a ceramic hollow fiber membrane to maintain a high cell density during fermentation.
[0025] In any of the methods, the host's tolerance to high concentrations of a C7 building block can be improved through continuous cultivation in a selective environment.
[0026] The principal carbon source fed to the fermentation can derive from biological or non-biological feedstocks. In some embodiments, the biological feedstock is, includes, or derives from, monosaccharides, disaccharides, lignocellulose, hemicellulose, cellulose, lignin, levulinic acid and formic acid, triglycerides, glycerol, fatty acids, agricultural waste, condensed distillers' solubles, or municipal waste.
[0027] In some embodiments, the non-biological feedstock is or derives from natural gas, syngas, CO.sub.2/H.sub.2, methanol, ethanol, benzoate, non-volatile residue (NVR) or a caustic wash waste stream from cyclohexane oxidation processes, or a terephthalic acid/isophthalic acid mixture waste stream.
[0028] This document also features a recombinant host that includes at least one exogenous nucleic acid encoding a monooxygenase encoded by BioI (in the CYP107H family) and an aldehyde dehydrogenase, the host producing pimeloyl-[acp] and heptanoate. The host further can include one or more of a monooxygenase (e.g., in the CYP153 family), a thioesterase, an aldehyde dehydrogenase, a 6-hydroxyhexanoate dehydrogenase, a 5-hydroxypentanoate dehydrogenase, a 4-hydroxybutyrate dehydrogenase, a 6-oxohexanoate dehydrogenase, a 7-oxoheptanoate dehydrogenase, or a carboxylate reductase, the host producing pimelic acid, pimelate semialdehyde, or 7-hydroxyheptanoate. In any of the recombinant hosts expressing a carboxylate reductase, a phosphopantetheinyl transferase also can be expressed to enhance the activity of the carboxylate reductase. In any of the recombinant hosts expressing a monooxygenase, an electron transfer chain protein such as an oxidoreductase and/or a ferredoxin polypeptide also can be expressed
[0029] A recombinant host producing pimelate semialdehyde, 7-hydroxyheptanoate, or 7-aminoheptanoate further can include one or more of a carboxylate reductase, a co-transaminase, a deacetylase, an N-acetyl transferase, or an alcohol dehydrogenase, the host producing heptamethylenediamine.
[0030] A recombinant host producing pimelate semilaldehyde further can include a co-transaminase, and produce 7-aminoheptanoate.
[0031] A recombinant host producing 7-hydroxyheptanoate further can include a carboxylate reductase or an alcohol dehydrogenase, the host producing 1,7-heptanediol.
[0032] The recombinant host can be a prokaryote, e.g., from the genus Escherichia such as Escherichia coli; from the genus Clostridia such as Clostridium ljungdahlii, Clostridium autoethanogenum or Clostridium kluyveri; from the genus Corynebacteria such as Corynebacterium glutamicum; from the genus Cupriavidus such as Cupriavidus necator or Cupriavidus metallidurans; from the genus Pseudomonas such as Pseudomonas fluorescens, Pseudomonas putida or Pseudomonas oleavorans; from the genus Delftia acidovorans, from the genus Bacillus such as Bacillus subtillis; from the genes Lactobacillus such as Lactobacillus delbrueckii; from the genus Lactococcus such as Lactococcus lactis or from the genus Rhodococcus such as Rhodococcus equi.

[0034] In some embodiments, the host's endogenous biochemical network is attenuated or augmented to (1) ensure the intracellular availability of acetyl-CoA, (2) create an NADPH imbalance that may only be balanced via the formation of C7 Building Blocks, (3) prevent degradation of central metabolites, central precursors leading to and including C7 Building Blocks and (4) ensure efficient efflux from the cell.
[0035] Any of the recombinant hosts described herein further can include one or more of the following attenuated enzymes: polyhydroxyalkanoate synthase, an acetyl-CoA thioesterase, an acetyl-CoA specific .beta.-ketothiolase, a phosphotransacetylase forming acetate, an acetate kinase, a lactate dehydrogenase, a menaquinol-fumarate oxidoreductase, a 2-oxoacid decarboxylase producing isobutanol, an alcohol dehydrogenase forming ethanol, a triose phosphate isomerase, a pyruvate decarboxylase, a glucose-6-phosphate isomerase, NADPH-consuming transhydrogenase, an NADH-specific glutamate dehydrogenase, a NADH/NADPH-utilizing glutamate dehydrogenase, a pimeloyl-CoA dehydrogenase; an acyl-CoA dehydrogenase accepting C7 building blocks and central precursors as substrates; a glutaryl-CoA dehydrogenase; or a pimeloyl-CoA synthetase.

Alternatively, relevant enzymes can be extracted from any of the above types of host cells and used in a purified or semi-purified form. Extracted enzymes can optionally be immobilized to a solid substrate such as the floors and/or walls of appropriate reaction vessels. Moreover, such extracts include lysates (e.g. cell lysates) that can be used as sources of relevant enzymes. In the methods provided by the document, all the steps can be performed in cells (e.g., host cells), all the steps can be performed using extracted enzymes, or some of the steps can be performed in cells and others can be performed using extracted enzymes.
[0038] Many of the enzymes described herein catalyze reversible reactions, and the reaction of interest may be the reverse of the described reaction. The schematic pathways shown in FIGS. 1-6 illustrate the reaction of interest for each of the intermediates.
[0039] In some embodiments, the host microorganism's endogenous biochemical network is attenuated or augmented to (1) ensure the intracellular availability of acetyl-CoA and malonyl-CoA, (2) create a NADPH imbalance that may only be balanced via fatty acid synthesis and the formation of a C7 building block, (3) prevent degradation of central metabolites or central precursors leading to and including C7 building blocks and (4) ensure efficient efflux from the cell.
[0040] In some embodiments, the cultivation strategy entails preventing the incorporation of fatty acids into lipid bodies or other carbon storage units.

DETAILED DESCRIPTION
[0062] This document provides enzymes, non-natural pathways, cultivation strategies, feedstocks, host microorganisms and attentions to the host's biochemical network, which generates a seven carbon chain aliphatic backbone from central metabolites in which one or two terminal functional groups may be formed leading to the synthesis of pimelic acid, 7-aminoheptanoic acid, 7-hydroxyheptanoic acid, heptamethylenediamine or 1,7-heptanediol (referred to as "C7 building blocks" herein). As used herein, the term "central precursor" is used to denote any metabolite in any metabolic pathway shown herein leading to the synthesis of a C7 building block. The term "central metabolite" is used herein to denote a metabolite that is produced in microorganisms to support growth.
[0063] Host microorganisms described herein can include endogenous pathways that can be manipulated such that one or more C7 building blocks can be produced. In an endogenous pathway, the host microorganism naturally expresses all of the enzymes catalyzing the reactions within the pathway. A host microorganism containing an engineered pathway does not naturally express all of the enzymes catalyzing the reactions within the pathway but has been engineered such that all of the enzymes within the pathway are expressed in the host.
[0064] The term "exogenous" as used herein with reference to a nucleic acid (or a protein) and a host refers to a nucleic acid that does not occur in (and cannot be obtained from) a cell of that particular type as it is found in nature or a protein encoded by such a nucleic acid. Thus, a non-naturally-occurring nucleic acid is considered to be exogenous to a host once in the host. It is important to note that non-naturally-occurring nucleic acids can contain nucleic acid subsequences or fragments of nucleic acid sequences that are found in nature provided the nucleic acid as a whole does not exist in nature. For example, a nucleic acid molecule containing a genomic DNA sequence within an expression vector is non-naturally-occurring nucleic acid, and thus is exogenous to a host cell once introduced into the host, since that nucleic acid molecule as a whole (genomic DNA plus vector DNA) does not exist in nature. Thus, any vector, autonomously replicating plasmid, or virus (e.g., retrovirus, adenovirus, or herpes virus) that as a whole does not exist in nature is considered to be non-naturally-occurring nucleic acid. It follows that genomic DNA fragments produced by PCR or restriction endonuclease treatment as well as cDNAs are considered to be non-naturally-occurring nucleic acid since they exist as separate molecules not found in nature. It also follows that any nucleic acid containing a promoter sequence and polypeptide-encoding sequence (e.g., cDNA or genomic DNA) in an arrangement not found in nature is non-naturally-occurring nucleic acid. A nucleic acid that is naturally-occurring can be exogenous to a particular host microorganism. For example, an entire chromosome isolated from a cell of yeast x is an exogenous nucleic acid with respect to a cell of yeast y once that chromosome is introduced into a cell of yeast y.
[0065] In contrast, the term "endogenous" as used herein with reference to a nucleic acid (e.g., a gene) (or a protein) and a host refers to a nucleic acid (or protein) that does occur in (and can be obtained from) that particular host as it is found in nature. Moreover, a cell "endogenously expressing" a nucleic acid (or protein) expresses that nucleic acid (or protein) as does a host of the same particular type as it is found in nature. Moreover, a host "endogenously producing" or that "endogenously produces" a nucleic acid, protein, or other compound produces that nucleic acid, protein, or compound as does a host of the same particular type as it is found in nature.
[0066] For example, depending on the host and the compounds produced by the host, one or more of the following enzymes may be expressed in the host in addition to a monooxygenase (e.g., in the CYP107H family, encoded by bioI) and an aldehyde dehydrogenase: a monooxygenase from, for example, the CYP153A family, a thioesterase, an aldehyde dehydrogenase, an alcohol dehydrogenase, a 6-oxohexanoate dehydrogenase, a 7-oxoheptanoate dehydrogenase, a .omega.-transaminase, a 6-hydroxyhexanoate dehydrogenase, a 5-hydroxypentanoate dehydrogenase, 4-hydroxybutyrate dehydrogenase, a carboxylate reductase and an enhancer, a deacetylase, or an N-acetyl transferase. In recombinant hosts expressing a carboxylate reductase, a phosphopantetheinyl transferase also can be expressed as it enhances activity of the carboxylate reductase. In recombinant hosts expressing a monooxygenase, an electron transfer chain protein such as an oxidoreductase and/or a ferredoxin polypeptide also can be expressed.
[0067] In some embodiments, a recombinant host can include at least one exogenous nucleic acid encoding a monooxygenase (e.g., encoded by bioI) and an aldehyde dehydrogenase, and produce pimeloyl-[acp] or heptanoate.
[0068] A recombinant host producing pimeloyl-[acp] or heptanoate further can include one or more of a thioesterase, an alcohol dehydrogenase, an aldehyde dehydrogenase, a 6-hydroxyhexanoate dehydrogenase, a 6-oxohexanoate dehydrogenase, a 5-hydroxypentanoate dehydrogenase, a 4-hydroxybutyrate dehydrogenase, a 7-oxoheptanoate dehydrogenase, or a carboxylate reductase and produce pimelic acid or pimelate semialdehyde. For example, a recombinant host further can include a thioesterase and produce pimelic acid. As another example, a recombinant host further can include (i) a monooxygenase from, for example, the CYP153 family, (ii) a 6-hydroxyhexanoate dehydrogenase, a 5-hydroxypentanoate dehydrogenase, or a 4-hydroxybutyrate dehydrogenase and (iii) and a 6-oxohexanoate dehydrogenase or a 7-oxoheptanoate dehydrogenase, and produce pimelic acid.
[0069] A recombinant host producing pimeloyl-[acp] or heptanoate further can include one or more of a monooxygenase, a transaminase, a 6-hydroxyhexanoate dehydrogenase, a 5-hydroxypentanoate dehydrogenase, or a 4-hydroxybutyrate dehydrogenase, and produce 7-aminoheptanoate. For example, a recombinant host further can include each of a monooxygenase, a transaminase, and a 6-hydroxyhexanoate dehydrogenase.
[0070] A recombinant host producing pimelic and/or heptanoate further can include a monooxygenase, a carboxylate reductase, a 6-hydroxyhexanoate dehydrogenase, a 5-hydroxypentanoate dehydrogenase, or a 4-hydroxybutyrate dehydrogenase and produce 7-hydroxyheptanoic acid. For example, a recombinant host producing heptanoate can include a monooxygenase such as a CYP153A and produce 7-hydroxyheptanoic acid. For example, a recombinant host producing pimelic acid can include (i) a carboxylate reductase and (ii) a 6-hydroxyhexanoate dehydrogenase, a 5-hydroxypentanoate dehydrogenase, or a 4-hydroxybutyrate dehydrogenase and produce 7-hydroxyheptanoic acid.
[0071] A recombinant host producing 7-aminoheptanoate, 7-hydroxyheptanoate, or pimelate semialdehyde further can include one or more of a carboxylate reductase, a .omega.-transaminase, a deacetylase, an N-acetyl transferase, or an alcohol dehydrogenase, and produce heptamethylenediamine. In some embodiments, a recombinant host further can include each of a carboxylate reductase, a .omega.-transaminase, a deacetylase, and an N-acetyl transferase. In some embodiments, a recombinant host further can include a carboxylate reductase and a .omega.-transaminase. In some embodiments, a recombinant host further can include a carboxylate reductase, a .omega.-transaminase, and an alcohol dehydrogenase.
[0072] A recombinant host producing 7-hydroxyheptanoic acid further can include one or more of a carboxylate reductase and an alcohol dehydrogenase, and produce 1,7-heptanediol.
[0073] Within an engineered pathway, the enzymes can be from a single source, i.e., from one species or genus, or can be from multiple sources, i.e., different species or genera. Nucleic acids encoding the enzymes described herein have been identified from various organisms and are readily available in publicly available databases such as GenBank or EMBL.
[0074] Any of the enzymes described herein that can be used for production of one or more C7 building blocks can have at least 70% sequence identity (homology) (e.g., at least 75%, 80%, 85%, 90%, 95%, 97%, 98%, 99%, or 100%) to the amino acid sequence of the corresponding wild-type enzyme. It will be appreciated that the sequence identity can be determined on the basis of the mature enzyme (e.g., with any signal sequence removed).
[0075] For example, a thioesterase described herein can have at least 70% sequence identity (homology) (e.g., at least 75%, 80%, 85%, 90%, 95%, 97%, 98%, 99%, or 100%) to the amino acid sequence of an Escherichia coli thioesterase encoded by tesA (see GenBank Accession No. AAA24664.1, SEQ ID NO: 1), a Bacteroides thetaiotaomicron acyl-[acp] thioesterase (see Genbank Accession No. AA077182, SEQ ID NO:23), or a Lactobacillus plantarum acyl-[acp] thioesterase (see Genbank Accession No. CCC78182.1, SEQ ID NO:24). See FIG. 7.
[0076] For example, a carboxylate reductase described herein can have at least 70% sequence identity (homology) (e.g., at least 75%, 80%, 85%, 90%, 95%, 97%, 98%, 99%, or 100%) to the amino acid sequence of a Mycobacterium marinum (see Genbank Accession No. ACC40567.1, SEQ ID NO: 2), a Mycobacterium smegmatis (see Genbank Accession No. ABK71854.1, SEQ ID NO: 3), a Segniliparus rugosus (see Genbank Accession No. EFV11917.1, SEQ ID NO: 4), a Mycobacterium smegmatis (see Genbank Accession No. ABK75684.1, SEQ ID NO: 5), a Mycobacterium massiliense (see Genbank Accession No. EIV11143.1, SEQ ID NO: 6), or a Segniliparus rotundus (see Genbank Accession No. ADG98140.1, SEQ ID NO: 7) carboxylate reductase. See, FIG. 7.
[0077] For example, a .omega.-transaminase described herein can have at least 70% sequence identity (homology) (e.g., at least 75%, 80%, 85%, 90%, 95%, 97%, 98%, 99%, or 100%) to the amino acid sequence of a Chromobacterium violaceum (see Genbank Accession No. AAQ59697.1, SEQ ID NO: 8), a Pseudomonas aeruginosa (see Genbank Accession No. AAG08191.1, SEQ ID NO: 9), a Pseudomonas syringae (see Genbank Accession No. AAY39893.1, SEQ ID NO: 10), a Rhodobacter sphaeroides (see Genbank Accession No. ABA81135.1, SEQ ID NO: 11), an Escherichia coli (see Genbank Accession No. AAA57874.1, SEQ ID NO: 12), or a Vibrio fluvialis (see Genbank Accession No. AEA39183.1, SEQ ID NO: 13) .omega.-transaminase. Some of these .omega.-transaminases are diamine .omega.-transaminases. See, FIG. 7.
[0078] For example, a monooxygenase described herein can have at least 70% sequence identity (homology) (e.g., at least 75%, 80%, 85%, 90%, 95%, 97%, 98%, 99%, or 100%) to the amino acid sequence of a Polaromonas sp. JS666 monooxygenase (see Genbank Accession No. ABE47160.1, SEQ ID NO:14), a Mycobacterium sp. HXN-1500 monooxygenase (see Genbank Accession No. CAH04396.1, SEQ ID NO:15), or a Mycobacterium austroafricanum monooxygenase (See Genbank Accession No. ACJ06772.1, SEQ ID NO:16). See, FIG. 7.
[0079] For example, an oxidoreductase described herein can have at least 70% sequence identity (homology) (e.g., at least 75%, 80%, 85%, 90%, 95%, 97%, 98%, 99%, or 100%) to the amino acid sequence of a Polaromonas sp. JS666 oxidoreductase (see Genbank Accession No. ABE47159.1, SEQ ID NO:17) or a Mycobacterium sp. HXN-1500 oxidoreductase (see Genbank Accession No. CAH04397.1, SEQ ID NO:18). See, FIG. 7.
[0080] For example, a ferredoxin polypeptide described herein can have at least 70% sequence identity (homology) (e.g., at least 75%, 80%, 85%, 90%, 95%, 97%, 98%, 99%, or 100%) to the amino acid sequence of a Polaromonas sp. JS666 ferredoxin (see Genbank Accession No. ABE47158.1, SEQ ID NO:19) or a Mycobacterium sp. HXN-1500 ferredoxin (see Genbank Accession No. CAH04398.1, SEQ ID NO:20). See, FIG. 7.
[0081] For example, a phosphopantetheinyl transferase described herein can have at least 70% sequence identity (homology) (e.g., at least 75%, 80%, 85%, 90%, 95%, 97%, 98%, 99%, or 100%) to the amino acid sequence of a Bacillus subtilis phosphopantetheinyl transferase (see Genbank Accession No. CAA44858.1, SEQ ID NO:21) or a Nocardia sp. NRRL 5646 phosphopantetheinyl transferase (see Genbank Accession No. ABI83656.1, SEQ ID NO:22). See FIG. 7.
[0082] The percent identity (homology) between two amino acid sequences can be determined as follows. First, the amino acid sequences are aligned using the BLAST 2 Sequences (B12seq) program from the stand-alone version of BLASTZ containing BLASTP version 2.0.14. This stand-alone version of BLASTZ can be obtained from Fish & Richardson's web site (e.g., www.fr.com/blast/) or the U.S. government's National Center for Biotechnology Information web site (www.ncbi.nlm.nih.gov). Instructions explaining how to use the Bl2seq program can be found in the readme file accompanying BLASTZ. Bl2seq performs a comparison between two amino acid sequences using the BLASTP algorithm. To compare two amino acid sequences, the options of Bl2seq are set as follows: -i is set to a file containing the first amino acid sequence to be compared (e.g., C:\seq1.txt); -j is set to a file containing the second amino acid sequence to be compared (e.g., C:\seq2.txt); -p is set to blastp; -o is set to any desired file name (e.g., C:\output.txt); and all other options are left at their default setting. For example, the following command can be used to generate an output file containing a comparison between two amino acid sequences: C:\B12seq -i c:\seq1.txt -j c:\seq2.txt -p blastp -o c:\output.txt. If the two compared sequences share homology (identity), then the designated output file will present those regions of homology as aligned sequences. If the two compared sequences do not share homology (identity), then the designated output file will not present aligned sequences. Similar procedures can be following for nucleic acid sequences except that blastn is used.
[0083] Once aligned, the number of matches is determined by counting the number of positions where an identical amino acid residue is presented in both sequences. The percent identity (homology) is determined by dividing the number of matches by the length of the full-length polypeptide amino acid sequence followed by multiplying the resulting value by 100. It is noted that the percent identity (homology) value is rounded to the nearest tenth. For example, 78.11, 78.12, 78.13, and 78.14 is rounded down to 78.1, while 78.15, 78.16, 78.17, 78.18, and 78.19 is rounded up to 78.2. It also is noted that the length value will always be an integer.
[0084] It will be appreciated that a number of nucleic acids can encode a polypeptide having a particular amino acid sequence. The degeneracy of the genetic code is well known to the art; i.e., for many amino acids, there is more than one nucleotide triplet that serves as the codon for the amino acid. For example, codons in the coding sequence for a given enzyme can be modified such that optimal expression in a particular species (e.g., bacteria or fungus) is obtained, using appropriate codon bias tables for that species.
[0085] Functional fragments of any of the enzymes described herein can also be used in the methods of the document. The term "functional fragment" as used herein refers to a peptide fragment of a protein that has at least 25% (e.g., at least: 30%; 40%; 50%; 60%; 70%; 75%; 80%; 85%; 90%; 95%; 98%; 99%; 100%; or even greater than 100%) of the activity of the corresponding mature, full-length, wild-type protein. The functional fragment can generally, but not always, be comprised of a continuous region of the protein, wherein the region has functional activity.
[0086] This document also provides (i) functional variants of the enzymes used in the methods of the document and (ii) functional variants of the functional fragments described above. Functional variants of the enzymes and functional fragments can contain additions, deletions, or substitutions relative to the corresponding wild-type sequences. Enzymes with substitutions will generally have not more than 50 (e.g., not more than one, two, three, four, five, six, seven, eight, nine, ten, 12, 15, 20, 25, 30, 35, 40, or 50) amino acid substitutions (e.g., conservative substitutions). This applies to any of the enzymes described herein and functional fragments. A conservative substitution is a substitution of one amino acid for another with similar characteristics. Conservative substitutions include substitutions within the following groups: valine, alanine and glycine; leucine, valine, and isoleucine; aspartic acid and glutamic acid; asparagine and glutamine; serine, cysteine, and threonine; lysine and arginine; and phenylalanine and tyrosine. The nonpolar hydrophobic amino acids include alanine, leucine, isoleucine, valine, proline, phenylalanine, tryptophan and methionine. The polar neutral amino acids include glycine, serine, threonine, cysteine, tyrosine, asparagine and glutamine. The positively charged (basic) amino acids include arginine, lysine and histidine. The negatively charged (acidic) amino acids include aspartic acid and glutamic acid. Any substitution of one member of the above-mentioned polar, basic or acidic groups by another member of the same group can be deemed a conservative substitution. By contrast, a nonconservative substitution is a substitution of one amino acid for another with dissimilar characteristics.
[0087] Deletion variants can lack one, two, three, four, five, six, seven, eight, nine, ten, 11, 12, 13, 14, 15, 16, 17, 18, 19, or 20 amino acid segments (of two or more amino acids) or non-contiguous single amino acids. Additions (addition variants) include fusion proteins containing: (a) any of the enzymes described herein or a fragment thereof; and (b) internal or terminal (C or N) irrelevant or heterologous amino acid sequences. In the context of such fusion proteins, the term "heterologous amino acid sequences" refers to an amino acid sequence other than (a). A heterologous sequence can be, for example a sequence used for purification of the recombinant protein (e.g., FLAG, polyhistidine (e.g., hexahistidine), hemagglutinin (HA), glutathione-S-transferase (GST), or maltosebinding protein (MBP)). Heterologous sequences also can be proteins useful as detectable markers, for example, luciferase, green fluorescent protein (GFP), or chloramphenicol acetyl transferase (CAT). In some embodiments, the fusion protein contains a signal sequence from another protein. In certain host cells (e.g., yeast host cells), expression and/or secretion of the target protein can be increased through use of a heterologous signal sequence. In some embodiments, the fusion protein can contain a carrier (e.g., KLH) useful, e.g., in eliciting an immune response for antibody generation) or ER or Golgi apparatus retention signals. Heterologous sequences can be of varying length and in some cases can be a longer sequences than the full-length target proteins to which the heterologous sequences are attached.
[0088] Engineered hosts can naturally express none or some (e.g., one or more, two or more, three or more, four or more, five or more, or six or more) of the enzymes of the pathways described herein. Thus, a pathway within an engineered host can include all exogenous enzymes, or can include both endogenous and exogenous enzymes. Endogenous genes of the engineered hosts also can be disrupted to prevent the formation of undesirable metabolites or prevent the loss of intermediates in the pathway through other enzymes acting on such intermediates. Engineered hosts can be referred to as recombinant hosts or recombinant host cells. As described herein recombinant hosts can include nucleic acids encoding one or more of a dehydrogenase, a synthetase, a .beta.-ketothiolase, a .beta.-ketoacyl-[acp] synthase, a carboxylase, a reductase, a dehydratase, a hydratase, a thioesterase, a monooxygenase, or a .omega.-transaminase as described herein.
[0089] In addition, the production of one or more C7 building blocks can be performed in vitro using the isolated enzymes described herein, using a lysate (e.g., a cell lysate) from a host microorganism as a source of the enzymes, or using a plurality of lysates from different host microorganisms as the source of the enzymes.
Enzymes Generating the C7 Aliphatic Backbone for Conversion to C7 Building Blocks
[0090] As depicted in FIG. 1, the C7 aliphatic backbone for conversion to one or more C7 building blocks can be formed from fatty acid synthesis using acetyl-CoA and malonyl-CoA as central metabolites and a monooxygenase such as that encoded by BioI for oxidative cleavage of long chain acyl-[acp] precursor (e.g., tetradecanoyl-[acp]).
[0091] In some embodiments, a long chain acyl-[acp] precursor such as tetradecanoyl-[acp] is cleaved by a monooxygenase classified, for example, under EC 1.14.15.12. In some embodiments, the monooxygenase is the gene product encoded by BioI from a microorganism such as Bacillus subtilis. See, for example, Stok and De Voss, 2000, Archives of Biochemistry and Biophysics, 384(2), 351-360; Cryle and De Voss, 2004, Chem. Comm., 86-87; Cryle and Schlichting, 2008, Proc. Natl. Acad. Sci., 105(41), 15696-15701; Cryle, 2010, Biochemical Society Transactions, 38(4), 934-939.
[0092] In some embodiments, the intermediate product (e.g., threo-7,8-dihydroxytetradecanoyl-[acp]) is converted to the respective carboxylic acids by the monooxygenase encoded by BioI, producing 7-oxoheptanoyl-[acp] and heptanal (see, for example, Cryle and De Voss, 2004, supra). See FIG. 1.
[0093] In some embodiments, the semialdehyde products formed by the monooxygenase encoded by BioI are converted to their respective carboxylic acids by an aldehyde dehydrogenase classified, for example, under EC 1.2.1.4 (see, Ho & Weiner, J. Bacteriol., 2005, 187(3):1067-1073) or classified, for example, under EC 1.2.1.3 (see, Guerrillot & Vandecasteele, Eur. J. Biochem., 1977, 81, 185-19). See FIG. 1.
Enzymes Generating the Terminal Carboxyl Groups in the Biosynthesis of C7 Building Blocks
[0094] As depicted in FIG. 1 and FIG. 2, terminal carboxyl groups can be enzymatically formed using a thioesterase, an aldehyde dehydrogenase, a 7-oxoheptanoate dehydrogenase or a 6-oxohexanoate dehydrogenase.
[0095] In some embodiments, the first terminal carboxyl group leading to the synthesis of a C7 building block is enzymatically formed by a monooxygenase such as a monooxygenase encoded by BioI.
[0096] In some embodiments, the first terminal carboxyl group leading to the synthesis of a C7 building block can be enzymatically formed by a thioesterase classified under EC 3.1.2.-, such as the gene product offatB or tesA (see, for example, GenBank Accession No. AA077182 and GenBank Accession No. CCC78182.1) (Cantu et al., Protein Science, 2010, 19, 1281-1295; Jing et al., 2011, BMC Biochemistry, 12:44)).
[0097] In some embodiments, the first terminal carboxyl group leading to the synthesis of a C7 building block is enzymatically formed by an aldehyde dehydrogenase classified, for example, under EC 1.2.1.4 (see, Ho & Weiner, J. Bacteriol., 2005, 187(3):1067-1073).
[0098] In some embodiments, the second terminal carboxyl group leading to the synthesis of pimelic acid is enzymatically formed by an aldehyde dehydrogenase classified, for example, under EC 1.2.1.3 (see, Guerrillot & Vandecasteele, Eur. J. Biochem., 1977, 81, 185-192).
[0099] In some embodiments, the second terminal carboxyl group leading to the synthesis of pimelic acid is enzymatically formed by a dehydrogenase classified under EC 1.2.1.- such as a 6-oxohexanoate dehydrogenase such as the gene product of ChnE from Acinetobacter sp. or 7-oxoheptanoate dehydrogenase such as the gene product of ThnG from Sphingomonas macrogolitabida (Iwaki et al., Appl. Environ. Microbiol., 1999, 65(11), 5158-5162; Lopez-Sanchez et al., Appl. Environ. Microbiol., 2010, 76(1), 110-118). For example, a 6-oxohexanoate dehydrogenase can be classified under EC 1.2.1.63. For example, a 7-oxoheptanoate dehydrogenase can be classified under EC 1.2.1.-.
[0100] It has been demonstrated in a Bacillus subtillis host that overexpression of the endogenes genes BioI, orf2 and orf3 overproduced pimelic acid (Zhang et al., 2011, Electronic Journal of Biotechnology, 14(6)).
Enzymes Generating the Terminal Amine Groups in the Biosynthesis of C7 Building Blocks
[0101] As depicted in FIG. 3 and FIG. 4, the terminal amine groups can be enzymatically formed using a .omega.-transaminase or a deacetylase.
[0102] In some embodiments, the first terminal amine group leading to the synthesis of 7-aminoheptanoic acid is enzymatically formed by a .omega.-transaminase classified, for example, under EC 2.6.1.18, EC 2.6.1.19, EC 2.6.1.29, EC 2.6.1.48, or EC 2.6.1.82 such as that obtained from Chromobacterium violaceum (Genbank Accession No. AAQ59697.1, SEQ ID NO: 8), Pseudomonas aeruginosa (Genbank Accession No. AAG08191.1, SEQ ID NO: 9), Pseudomonas syringae (Genbank Accession No. AAY39893.1, SEQ ID NO: 10), Rhodobacter sphaeroides (Genbank Accession No. ABA81135.1, SEQ ID NO: 11), Vibrio Fluvialis (Genbank Accession No. AAA57874.1, SEQ ID NO: 13), Streptomyces griseus, or Clostridium viride. An additional .omega.-transaminase that can be used in the methods and hosts described herein is from Escherichia coli (Genbank Accession No. AAA57874.1, SEQ ID NO: 12). Some of the .omega.-transaminases classified, for example, under EC 2.6.1.29 or EC 2.6.1.82 are diamine .omega.-transaminases (e.g., SEQ ID NO:12).
[0103] The reversible .omega.-transaminase from Chromobacterium violaceum (Genbank Accession No. AAQ59697.1, SEQ ID NO: 8) has demonstrated analogous activity accepting 6-aminohexanoic acid as amino donor, thus forming the first terminal amine group in adipate semialdehyde (Kaulmann et al., Enzyme and Microbial Technology, 2007, 41, 628-637).
[0104] The reversible 4-aminobubyrate:2-oxoglutarate transaminase from Streptomyces griseus has demonstrated analogous activity for the conversion of 6-aminohexanoate to adipate semialdehyde (Yonaha et al., Eur. J. Biochem., 1985, 146, 101-106).
[0105] The reversible 5-aminovalerate transaminase from Clostridium viride has demonstrated analogous activity for the conversion of 6-aminohexanoate to adipate semialdehyde (Barker et al., J. Biol. Chem., 1987, 262(19), 8994-9003).
[0106] In some embodiments, the second terminal amine group leading to the synthesis of heptamethylenediamine is enzymatically formed by a diamine transaminase. For example, the second terminal amino group can be enzymatically formed by a diamine transaminase classified, for example, under EC 2.6.1.29 or classified, for example, under EC 2.6.1.82, such as the gene product of YgjG from E. coli (Genbank Accession No. AAA57874.1, SEQ ID NO: 12).
[0107] The gene product of ygjG accepts a broad range of diamine carbon chain length substrates, such as putrescine, cadaverine and spermidine (Samsonova et al., BMC Microbiology, 2003, 3:2).
[0108] The diamine transaminase from E. coli strain B has demonstrated activity for 1,7 diaminoheptane (Kim, The Journal of Chemistry, 1964, 239(3), 783-786). In some embodiments, the second terminal amine group leading to the synthesis of heptamethylenediamine is enzymatically formed by a deacetylase classified, for example, under EC 3.5.1.62 such as an acetylputrescine deacetylase. The acetylputrescine deacetylase from Micrococcus luteus K-11 accepts a broad range of carbon chain length substrates, such as acetylputrescine, acetylcadaverine and N.sup.8_acetylspermidine (see, for example, Suzuki et al., 1986, BBA--General Subjects, 882(1):140-142).
Enzymes Generating the Terminal Hydroxyl Groups in the Biosynthesis of C7 Building Blocks
[0109] As depicted in FIG. 5 and FIG. 6, a terminal hydroxyl group can be enzymatically formed using a monooxygenase or an alcohol dehydrogenase.
[0110] In some embodiments, a terminal hydroxyl group leading to the synthesis of a C7 building block is enzymatically formed by a monooxygenase in the cytochrome P450 family. For example, the monooxygenase CYP153A family classified, for example, under EC 1.14.15.1 is soluble and has regio-specificity for terminal hydroxylation, accepting medium chain length substrates (see, e.g., Koch et al., Appl. Environ. Microbiol., 2009, 75(2), 337-344; Funhoff et al., 2006, J. Bacteriol., 188(44): 5220-5227; Van Beilen & Funhoff, Current Opinion in Biotechnology, 2005, 16, 308-314; Nieder and Shapiro, J. Bacteriol., 1975, 122(1), 93-98). Although non-terminal hydroxylation is observed in vitro for CYP153A, in vivo only 1-hydroxylation occurs (see, Funhoff et al., 2006, supra).
[0111] The substrate specificity and activity of terminal monooxygenases has been broadened via successfully, reducing the chain length specificity of CYP153A to below C8 (Koch et al., 2009, supra).
[0112] In some embodiments, a terminal hydroxyl group leading to the synthesis of 1,7 heptanediol is enzymatically formed by an alcohol dehydrogenase classified, for example, under EC 1.1.1.- (e.g., 1, 2, 21, or 184) such as the gene product of YMR318C (classified, for example, under EC 1.1.1.2, see Genbank Accession No. CAA90836.1) (Larroy et al., 2002, Biochem J., 361(Pt 1), 163-172), the gene product of the gene product of YghD, the gene product of cpnD (Iwaki et al., 2002, Appl.

Microbiol., 68(11):5671-5684), the gene product of gabD (Lutke-Eversloh & Steinbuchel, 1999, FEMS Microbiology Letters, 181(1):63-71), or a 6-hydroxyhexanoate dehydrogenase classified, for example, under EC 1.1.1.258 such as the gene product of ChnD (Iwaki et al., Appl. Environ. Microbiol., 1999, 65(11):5158-5162).

Such methods can involve, for example, one, two, three, four, five, six, seven, eight, nine, ten, eleven, twelve or more of such steps. Where less than all the steps are included in such a method, the first, and in some embodiments the only, step can be any one of the steps listed.
[0146] Furthermore, recombinant hosts described herein can include any combination of the above enzymes such that one or more of the steps, e.g., one, two, three, four, five, six, seven, eight, nine, ten, or more of such steps, can be performed within a recombinant host. This document provides host cells of any of the genera and species listed and genetically engineered to express one or more (e.g., two, three, four, five, six, seven, eight, nine, 10, 11, 12 or more) recombinant forms of any of the enzymes recited in the document. Thus, for example, the host cells can contain exogenous nucleic acids encoding enzymes catalyzing one or more of the steps of any of the pathways described herein.
[0147] In addition, this document recognizes that where enzymes have been described as accepting CoA-activated substrates, analogous enzyme activities associated with [acp]-bound substrates exist that are not necessarily in the same enzyme class.
[0148] Also, this document recognizes that where enzymes have been described accepting (R)-enantiomers of substrate, analogous enzyme activities associated with (S)-enantiomer substrates exist that are not necessarily in the same enzyme class.
[0149] This document also recognizes that where an enzyme is shown to accept a particular co-factor, such as NADPH, or co-substrate, such as acetyl-CoA, many enzymes are promiscuous in terms of accepting a number of different co-factors or co-substrates in catalyzing a particular enzyme activity. Also, this document recognizes that where enzymes have high specificity for e.g., a particular co-factor such as NADH, an enzyme with similar or identical activity that has high specificity for the co-factor NADPH may be in a different enzyme class.
[0150] In some embodiments, the enzymes in the pathways outlined herein are the result of enzyme engineering via non-direct or rational enzyme design approaches with aims of improving activity, improving specificity, reducing feedback inhibition, reducing repression, improving enzyme solubility, changing stereo-specificity, or changing co-factor specificity.

[0153] Attenuation strategies include, but are not limited to; the use of transposons, homologous recombination (double cross-over approach), mutagenesis, enzyme inhibitors and RNAi interference.
[0154] In some embodiments, fluxomic, metabolomic and transcriptomal data can be utilized to inform or support genome-scale system biology techniques, thereby devising genome scale attenuation or knockout strategies in directing carbon flux to a C7 building block.
[0155] In some embodiments, the host microorganism's tolerance to high concentrations of a C7 building block can be improved through continuous cultivation in a selective environment.
[0156] In some embodiments, the host microorganism's endogenous biochemical network can be attenuated or augmented to (1) ensure the intracellular availability of acetyl-CoA, (2) create an NADPH imbalance that may only be balanced via the formation of one or more C7 building blocks, (3) prevent degradation of central metabolites, central precursors leading to and including one or more C7 building blocks and/or (4) ensure efficient efflux from the cell.
[0157] In some embodiments requiring intracellular availability of acetyl-CoA for C7 building block synthesis, endogenous enzymes catalyzing the hydrolysis of acetyl-CoA such as short-chain length thioesterases can be attenuated in the host organism.
[0158] In some embodiments requiring availability of acetyl-CoA for fatty acid synthesis, one or more endogenous .beta.-ketothiolases catalyzing the condensation of acetyl-CoA to acetoacetyl-CoA such as the endogenous gene products of AtoB, bktB, or phaA can be attenuated.
[0159] In some embodiments requiring the availability of malonyl-CoA for fatty acid synthesis, an acetyl-CoA carboxylase can be constitutively overexpressed in the recombinant host.
[0160] In some embodiments requiring the intracellular availability of acetyl-CoA for C7 building block synthesis, an endogenous phosphotransacetylase generating acetate such as pta can be attenuated (Shen et al., Appl. Environ. Microbiol., 2011, 77(9):2905-2915).

Producing C7 Building Blocks Using a Recombinant Host
[0189] Typically, one or more C7 building blocks can be produced by providing a host microorganism and culturing the provided microorganism with a culture medium containing a suitable carbon source as described above. In general, the culture media and/or culture conditions can be such that the microorganisms grow to an adequate density and produce a C7 building block efficiently. For large-scale production processes, any method can be used such as those described elsewhere (Manual of Industrial Microbiology and Biotechnology, 2.sup.nd Edition, Editors: A. L. Demain and J. E. Davies, ASM Press; and Principles of Fermentation Technology, P. F. Stanbury and A. Whitaker, Pergamon). Briefly, a large tank (e.g., a 100 gallon, 200 gallon, 500 gallon, or more tank) containing an appropriate culture medium is inoculated with a particular microorganism. After inoculation, the microorganism is incubated to allow biomass to be produced. Once a desired biomass is reached, the broth containing the microorganisms can be transferred to a second tank. This second tank can be any size. For example, the second tank can be larger, smaller, or the same size as the first tank. Typically, the second tank is larger than the first such that additional culture medium can be added to the broth from the first tank. In addition, the culture medium within this second tank can be the same as, or different from, that used in the first tank.
[0190] Once transferred, the microorganisms can be incubated to allow for the production of a C7 building block. Once produced, any method can be used to isolate C7 building blocks. For example, C7 building blocks can be recovered selectively from the fermentation broth via adsorption processes. In the case of pimelic acid and 7-aminoheptanoic acid, the resulting eluate can be further concentrated via evaporation, crystallized via evaporative and/or cooling crystallization, and the crystals recovered via centrifugation. In the case of heptamethylenediamine and 1,7-heptanediol, distillation may be employed to achieve the desired product purity.

Each of the resulting modified genes was cloned into a pET21a expression vector under control of the T7 promoter and each expression vector was transformed into a BL21[DE3] E. coli host. The resulting recombinant E. coli strains were cultivated at 37.degree. C. in a 250 mL shake flask culture containing 50 mL LB media and antibiotic selection pressure, with shaking at 230 rpm. Each culture was induced overnight at 16.degree. C. using 1 mM IPTG.
[0193] The pellet from each induced shake flask culture was harvested via centrifugation. Each pellet was resuspended and lysed via sonication. The cell debris was separated from the supernatant via centrifugation and the cell free extract was used immediately in enzyme activity assays.
