CROSS REFERENCE TO RELATED APPLICATIONS
[0001] This application claims priority to U.S. Provisional Application No. 62/263,299, filed Dec. 4, 2015, the contents of which are incorporated herein by reference.
TECHNICAL FIELD
[0002] This invention provides methods for biosynthesizing 7-carbon monomers. For example, the present invention provides methods for making N-acetyl-5-amino-3-oxopentanoyl-CoA or a salt thereof using a polypeptide having the activity of a .beta.-ketoacyl synthase or a .beta.-ketothiolase and enzymatically converting N-acetyl-5-amino-3-oxopentanoyl-CoA or a salt thereof to 7-aminoheptanoic acid or a salt thereof using one or more polypeptides having the activity of a 3-hydroxyacyl-CoA dehydrogenase, an enoyl-CoA hydratase, a trans-2-enoyl-CoA reductase, a .beta.-ketothiolase, a thioesterase or a CoA-transferase and a deacetylase or methods using microorganisms expressing one or more of such enzymes.

BACKGROUND
[0003] Nylons are synthetic polymers composed of polyamides which are generally synthesized by the condensation polymerization of a diamine with a dicarboxylic acid. Similarly, nylons also may be produced by the condensation polymerization of lactams. Nylon 7 is produced by polymerization of 7-aminoheptanoic acid, whereas Nylon 7,7 is produced by condensation polymerization of pimelic acid and heptamethylenediamine. No economically cost competitive petrochemical route exists to produce the monomers for Nylon 7 and Nylon 7,7.
[0004] Given no economically cost competitive petrochemical monomer feedstock, biotechnology offers an alternative approach via biocatalysis. Biocatalysis is the use of biological catalysts, such as enzymes, to perform biochemical transformations of, for example, bioderived feedstocks and petrochemical feedstocks which can both be viable starting materials for the biocatalysis processes.

DETAILED DESCRIPTION
[0080] In general, this document provides enzymes, non-natural pathways, cultivation strategies, feedstocks, microorganisms and attenuations to the microorganism's biochemical network, for producing 7-aminoheptanoate or one or more of pimelic acid, 7-hydroxyheptanoic acid, heptamethylenediamine or 1,7-heptanediol or the corresponding salts thereof, all of which are referred to as C7 building blocks herein. The term "C7 building block" is used to denote a seven (7) carbon chain aliphatic backbone. 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 all microorganisms to support growth.
[0081] Microorganisms described herein can include endogenous pathways that can be manipulated such that 7-aminoheptanoate or one or more other C7 building blocks can be produced. In an endogenous pathway, the microorganism naturally expresses all of the enzymes catalyzing the reactions within the pathway. A 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 microorganism.
[0082] The term "exogenous" as used herein with reference to a nucleic acid (or a protein) and a microorganism 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 microorganism once in the microorganism. 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 microorganism once introduced into the microorganism, 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 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.
[0083] In contrast, the term "endogenous" as used herein with reference to a nucleic acid (e.g., a gene) (or a protein) and a microorganism refers to a nucleic acid (or protein) that does occur in (and can be obtained from) that particular microorganism 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 microorganism of the same particular type as it is found in nature. Moreover, a microorganism "endogenously producing" or that "endogenously produces" a nucleic acid, protein, or other compound produces that nucleic acid, protein, or compound as does a microorganism of the same particular type as it is found in nature.
[0084] For example, depending on the microorganism and the compounds produced by the microorganism, one or more of the following polypeptides having the following specific enzymatic activities may be expressed in the microorganism in addition to a .beta.-ketoacyl synthase and/or a .beta.-ketothiolase:a 3-hydroxyacyl-CoA dehydrogenase, an enoyl-CoA hydratase, a trans-2-enoyl-CoA reductase, a thioesterase, a CoA transferase, a deacetylase, an aldehyde dehydrogenase, an alcohol dehydrogenase, a 7-oxoheptanoate dehydrogenase, a 6-oxohexanoate dehydrogenase, a 5-oxopentanoate dehydrogenase, a 6-hydroxyhexanoate dehydrogenase, a 4-hydroxybutanoate dehydrogenase, a 5-hydroxypentanoate dehydrogenase, a carboxylate reductase, an N-acetyl transferase, or a .omega.-transaminase. In recombinant microorganisms expressing a polypeptide having the activity of a carboxylate reductase, a phosphopantetheinyl transferase also can be expressed as it enhances activity of the carboxylate reductase.
[0085] For example, a recombinant microorganism can include a polypeptide having the activity of an exogenous .beta.-ketoacyl synthase or a .beta.-ketothiolase and produce N-acetyl-5-amino-3-oxopentanoyl-CoA or a salt thereof from N-acetyl-3-aminopropanoyl-CoA. The N-acetyl-5-amino-3-oxopentanoyl-CoA or salt thereof can be converted enzymatically to N-acetyl-7-aminoheptanoyl-CoA and subsequently to 7-aminoheptanoate.
[0086] For example, a recombinant microorganism can include a polypeptide having the activity of an exogenous .beta.-ketoacyl synthase and a .beta.-ketothiolase, an exogenous thioesterase or CoA-transferase, a deacetylase, a 3-hydroxyacyl-CoA dehydrogenase, an enoyl-CoA hydratase, and a trans-2-enoyl-CoA reductase and produce 7-aminoheptanoate.
[0087] For example, a recombinant microorganism producing 7-aminoheptanoate can include one or more of the following exogenous polypeptides having the enzymatic activity of: a .omega.-transaminase, a 7-oxoheptanoate dehydrogenase, a 5-oxopentanoate dehydrogenase, a 6-oxohexanoate dehydrogenase, or an aldehyde dehydrogenase, and further produce pimelic acid. For example, a recombinant microorganism producing 7-aminoheptanoate can include an exogenous .omega.-transaminase and an aldehyde dehydrogenase and produce pimelic acid. For example, a recombinant microorganism producing 7-aminoheptanoate can include an exogenous polypeptide having the activity of a .omega.-transaminase and one of the following exogenous polypeptides having the enzymatic activity of: a 5-oxopentanoate dehydrogenase, a 6-oxohexanoate dehydrogenase, or a 7-oxoheptanoate dehydrogenase, and produce pimelic acid.
[0088] For example, a recombinant microorganism producing 7-aminoheptanoate can include one or more of the following exogenous polypeptides having the enzymatic activity of: a .omega.-transaminase, an alcohol dehydrogenase, a 6-hydroxyhexanoate dehydrogenase, a 5-hydroxypentanoate dehydrogenase, 4-hydroxybutanoate dehydrogenase, and further produce 7-hydroxyheptanoate. For example, a recombinant microorganism producing 7-aminoheptanoate can include an exogenous polypeptide having the activity of an alcohol dehydrogenase and an exogenous polypeptide having the activity of a .omega.-transaminase and produce 7-hydroxyheptanoate. For example, a recombinant microorganism producing 7-aminoheptanoate can include an exogenous polypeptide having the activity of a 6-hydroxyhexanoate dehydrogenase and an exogenous polypeptide having the activity of a .omega.-transaminase and produce 7-hydroxyheptanoate. For example, a recombinant microorganism producing 7-aminoheptanoate can include an exogenous polypeptide having the activity of a 5-hydroxypentanoate dehydrogenase and an exogenous polypeptide having the activity of a .omega.-transaminase and produce 7-hydroxyheptanoate. For example, a recombinant microorganism producing 7-aminoheptanoate can include an exogenous polypeptide having the activity of a 4-hydroxybutanoate dehydrogenase and an exogenous polypeptide having the activity of a .omega.-transaminase and produce 7-hydroxyheptanoate.
[0089] For example, a recombinant microorganism producing 7-aminoheptanoate can include one or more of the following exogenous polypeptides having the activity of: a carboxylate reductase, a .omega.-transaminase, a deacetylase, an N-acetyl transferase or an alcohol dehydrogenase, and produce heptamethylenediamine. For example, a recombinant microorganism producing 7-aminoheptanoate can include an exogenous polypeptide having the activity of a carboxylate reductase and one or more exogenous polypeptides having the activity of transaminases (e.g., one .omega.-transaminase or two different transaminases) and produce heptamethylenediamine. For example, a recombinant microorganism producing 7-aminoheptanoate can include an exogenous polypeptide having the activity of a carboxylate reductase, an exogenous polypeptide having the activity of a alcohol dehydrogenase, and one or more exogenous polypeptides having the activity of transaminases (e.g., one .omega.-transaminase or two different transaminases), and produce heptamethylenediamine. For example, a recombinant microorganism producing 7-aminoheptanoate can include an exogenous polypeptide having the activity of an N-acetyl transferase, a carboxylate reductase, a deacylase, and one or more exogenous transaminases (e.g., one .omega.-transaminase or two different transaminases) and produce heptamethylenediamine. For example, a recombinant microorganismproducing 7-aminoheptanoate can include one or more exogenous polypeptide having the activity of an alcohol dehydrogenase, and one or more exogenous polypeptides having the activity of transaminases (e.g., one .omega.-transaminase, or two or three different transaminases) and produce heptamethylenediamine.
[0090] For example, a recombinant microorganism producing 7-hydroxyheptanoate can include the following exogenous polypeptides having the enzymatic activity of: a carboxylate reductase and an exogenous alcohol dehydrogenase, and further produce 1,7-heptanediol.
[0091] In any of the recombinant microorganisms, the recombinant microorganism also can include one or more (e.g., one, two or three) of the following exogenous enzymes used to convert either malonyl-CoA or L-aspartate to .beta.-alanine: a malonyl-CoA reductase, an aspartate .alpha.-decarboxylase and a .beta.-alanine-pyruvate aminotransferase. For example, a recombinant microorganism can include an exogenous malonyl-CoA reductase and a .beta.-alanine-pyruvate aminotransferase and produce .beta.-alanine. For example, a recombinant microorganism can include an exogenous aspartate .alpha.-decarboxylase and produce .beta.-alanine.
[0092] In any of the recombinant microorganisms, the recombinant microorganism also can include following the exogenous enzyme used to convert .beta.-alanine to N-acetyl-3-aminopropanoate: an N-acetyl-transferase.
[0093] In any of the recombinant microorganisms, the recombinant microorganism also can include one or more (e.g., one or two) of the following exogenous enzymes used to convert N-acetyl-3-aminopropanoate to N-acetyl-3-aminopropanoyl-CoA: a CoA transferase or a CoA ligase.
[0094] In any of the recombinant microorganisms, the recombinant microorganism also can include one or more (e.g., one or two) of the following exogenous enzymes used to convert 5-ethanamidopentanoic acid to 5-ethanamidopentanoyl-CoA: a CoA transferase or a CoA ligase.
[0095] Within an engineered pathway, the enzymes can be from a single source, i.e., from one species or genera, 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 EMB L.
[0096] 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%, 91%, 92%, 93%, 94%, 95%, 96%, 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) or on the basis of the immature enzyme (e.g., with any signal sequence included). It also will be appreciated that the initial methionine residue may or may not be present on any of the enzyme sequences described herein.
[0097] For example, a .beta.-ketothiolase described herein can have at least 70% sequence identity (homology) (e.g., at least 75%, 80%, 85%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, 99%, or 100%) to the amino acid sequence of a Cupriavidus necator .beta.-ketothiolase (see GenBank Accession No. AAC38322.1, SEQ ID NO: 1) or an Escherichia coli .beta.-ketothiolase (see GenBank Accession No. AAC74479.1, SEQ ID NO: 13) See FIG. 7.
[0098] For example, a .beta.-ketoacyl synthase described herein can have at least 70% sequence identity (homology) (e.g., at least 75%, 80%, 85%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, 99%, or 100%) to the amino acid sequence of a Bacillus subtilis .beta.-ketoacyl synthase (see GenBank Accession No. CAA74523.1, SEQ ID NO: 14). See FIG. 7.
[0099] For example, a CoA-transferase described herein can have at least 70% sequence identity (homology) (e.g., at least 75%, 80%, 85%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, 99%, or 100%) to the amino acid sequence of a Clostridium aminobutyrium (see GenBank Accession No. CAB60036.2, SEQ ID NO: 19). See FIG. 7.
[0100] For example, a carboxylate reductase described herein can have at least 70% sequence identity (homology) (e.g., at least 75%, 80%, 85%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, 99%, or 100%) to the amino acid sequence of a Mycobacterium marinum carboxylate reductase (see Genbank Accession No. ACC40567.1, SEQ ID NO: 2), a Mycobacterium smegmatis carboxylate reductase (see Genbank Accession No. ABK71854.1, SEQ ID NO: 3), a Segniliparus rugosus carboxylate reductase (see Genbank Accession No. EFV11917.1, SEQ ID NO: 4), a Mycobacterium massiliense carboxylate reductase (see Genbank Accession No. EIV11143.1, SEQ ID NO: 5), a Segniliparus rotundus carboxylate reductase (see Genbank Accession No. ADG98140.1, SEQ ID NO: 6) carboxylate reductase or a Mycobacterium smegmatis carboxylate reductase (see Genbank Accession No. ABK75684.1, SEQ ID NO: 15). See, FIG. 7.
[0101] For example, a .omega.-transaminase described herein can have at least 70% sequence identity (homology) (e.g., at least 75%, 80%, 85%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, 99%, or 100%) to the amino acid sequence of a Chromobacterium violaceum .omega.-transaminase (see Genbank Accession No. AAQ59697.1, SEQ ID NO: 7), a Pseudomonas aeruginosa .omega.-transaminase (see Genbank Accession No. AAG08191.1, SEQ ID NO: 8), a Pseudomonas syringae .omega.-transaminase (see Genbank Accession No. AAY39893.1, SEQ ID NO: 9), a Rhodobacter sphaeroides .omega.-transaminase (see Genbank Accession No. ABA81135.1, SEQ ID NO: 10), an Escherichia coli transaminase (see Genbank Accession No. AAA57874.1, SEQ ID NO: 11), or a Vibrio fluvialis (see Genbank Accession No. AEA39183.1, SEQ ID NO: 12) .omega.-transaminase. Some of these .omega.-transaminases are diamine .omega.-transaminases. See, FIG. 7.
[0102] 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. B12seq 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:\seql.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.
[0103] 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.
[0104] 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.
[0105] 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.
[0106] 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 100 (e.g., not more than one, two, three, four, five, six, seven, eight, nine, ten, 12, 15, 20, 25, 30, 35, 40, 50 or 100) 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.
[0107] Deletion variants can lack one, two, three, four, five, six, seven, eight, nine, ten, 11, 12, 13, 14, 15, 16, 17, 18, 19, or 50 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., heptahistidine), 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 microorganisms (e.g., yeast 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.
[0108] Engineered microorganisms 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 microorganism can include all exogenous enzymes, or can include both endogenous and exogenous enzymes. Endogenous genes of the engineered microorganisms 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 microorganisms can be referred to as recombinant microorganisms or recombinant cells. As described herein recombinant microorganisms can include nucleic acids encoding one or more of a .beta.-ketoacyl synthase, a .beta.-ketothiolase, a dehydrogenase, a reductase, a hydratase, a CoA-transferase, a CoA-ligase, a thioesterase, a deacetylase, an N-acetyltransferase and .omega.-transaminase as described herein.
[0109] In addition, the production of C7 building blocks can be performed in vitro using the isolated enzymes described herein, using a lysate (e.g., a cell lysate) from a microorganism as a source of the enzymes, or using a plurality of lysates from different microorganisms as the source of the enzymes.
[0110] The reactions of the pathways described herein can be performed in one or more microorganisms (a) naturally expressing one or more relevant enzymes, (b) genetically engineered to express one or more relevant enzymes, or (c) naturally expressing one or more relevant enzymes and genetically engineered to express one or more relevant enzymes. Alternatively, relevant enzymes can be isolated, purified or extracted from of the above types of microorganism cells and used in a purified or semi-purified form. 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 microorganism 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.

[0147] In some embodiments, one or more C7 building blocks are biosynthesized in a recombinant microorganism using anaerobic, aerobic or micro-aerobic cultivation conditions. In some embodiments, the cultivation strategy entails nutrient limitation such as nitrogen, phosphate or oxygen limitation.
[0148] In some embodiments, a cell retention strategy using, for example, ceramic hollow fiber membranes can be employed to achieve and maintain a high cell density during either fed-batch or continuous fermentation.

Producing C7 Building Blocks Using a Recombinant Microorganism
[0210] Typically, one or more C7 building blocks can be produced by providing a 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.
[0211] 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.
[0212] The invention will be further described in the following examples, which do not limit the scope of the invention described in the claims.

Example 1
Enzyme activity of .omega.-transaminase using pimelate semialdehyde as substrate and forming 7-aminoheptanoate
[0213] A nucleotide sequence encoding a N-terminal His-tag was added to the nucleic acid sequences from Chromobacterium violaceum, Pseudomonas syringae, Rhodobacter sphaeroides, and Vibrio fluvialis encoding the .omega.-transaminases of SEQ ID NOs: 7, 9, 10 and 12, respectively (see FIG. 7) such that N-terminal His-tagged .omega.-transaminases could be produced. 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 strain.

Each culture was induced overnight at 16.degree. C. using 1 mM IPTG.
[0214] 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.
[0215] Enzyme activity assays in the reverse direction (i.e., 7-aminoheptanoate to pimelate semialdehyde) were performed in a buffer composed of a final concentration of 50 mM HEPES buffer (pH=7.5), 10 mM 7-aminoheptanoate, 10 mM pyruvate and 100 .mu.M pyridoxyl 5' phosphate. Each enzyme activity assay reaction was initiated by adding cell free extract of the .omega.-transaminase gene product or the empty vector control to the assay buffer containing the 7-aminoheptanoate and incubated at 25.degree. C. for 4 h, with shaking at 250 rpm. The formation of L-alanine from pyruvate was quantified via RP-HPLC.
[0216] Each enzyme only control without 7-aminoheptanoate demonstrated low base line conversion of pyruvate to L-alanine. See FIG. 13. The gene product of SEQ ID NO 7, SEQ ID NO 9, SEQ ID NO 10 and SEQ ID NO 12 accepted 7-aminoheptanote as substrate as confirmed against the empty vector control. See FIG. 14.

Enzyme activity assays were performed in a buffer composed of a final concentration of 50 mM HEPES buffer (pH=7.5), 10 mM pimelate semialdehyde, 10 mM L-alanine and 100 .mu.M pyridoxyl 5' phosphate.

C. for 4 h, with shaking at 250 rpm. The formation of pyruvate was quantified via RP-HPLC.
[0218] The gene product of SEQ ID NO 9, SEQ ID NO 10 and SEQ ID NO 12 accepted pimelate semialdehyde as substrate as confirmed against the empty vector control. See FIG. 15. The reversibility of the .omega.-transaminase activity was confirmed, demonstrating that the .omega.-transaminases of SEQ ID NO: 7, SEQ ID NO: 9, SEQ ID NO: 10, and SEQ ID NO: 12 accepted pimelate semialdehyde as substrate and synthesized 7-aminoheptanoate as a reaction product.

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 37.degree. C. using an auto-induction media.
[0220] The pellet from each induced shake flask culture was harvested via centrifugation. Each pellet was resuspended and lysed via sonication, and the cell debris was separated from the supernatant via centrifugation. The carboxylate reductases and phosphopantetheine transferases were purified from the supernatant using Ni-affinity chromatography, diluted 10-fold into 50 mM HEPES buffer (pH=7.5), and concentrated via ultrafiltration.

The consumption of NADPH was monitored by absorbance at 340 nm. Each enzyme only control without 7-hydroxyheptanoate demonstrated low base line consumption of NADPH. See FIG. 8.
[0226] The gene products of SEQ ID NO 2-6 and 15, enhanced by the gene product of sfp, accepted 7-hydroxyheptanoate as substrate as confirmed against the empty vector control (see FIG. 10), and synthesized 7-hydroxyheptanal.
Example 4
Enzyme activity of .omega.-transaminase for 7-aminoheptanol, forming 7-oxoheptanol
[0227] A nucleotide sequence encoding an N-terminal His-tag was added to the Chromobacterium violaceum, Pseudomonas syringae and Rhodobacter sphaeroides nucleic acids encoding the .omega.-transaminases of SEQ ID NOs: 7, 9 and 10, respectively (see FIG. 7) such that N-terminal HIS tagged .omega.-transaminases could be produced. The modified genes were cloned into a pET21a expression vector under the T7 promoter. Each expression vector was transformed into a BL21[DE3] E. coli strain. Each resulting recombinant E. coli strain 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.
[0228] 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.
[0229] Enzyme activity assays in the reverse direction (i.e., 7-aminoheptanol to 7-oxoheptanol) were performed in a buffer composed of a final concentration of 50 mM HEPES buffer (pH=7.5), 10 mM 7-aminoheptanol, 10 mM pyruvate, and 100 .mu.M pyridoxyl 5' phosphate. Each enzyme activity assay reaction was initiated by adding cell free extract of the .omega.-transaminase gene product or the empty vector control to the assay buffer containing the 7-aminoheptanol and then incubated at 25.degree. C. for 4 h, with shaking at 250 rpm. The formation of L-alanine was quantified via RP-HPLC.
[0230] Each enzyme only control without 7-aminoheptanol had low base line conversion of pyruvate to L-alanine. See FIG. 13.
[0231] The gene products of SEQ ID NOs: 7, 9 & 10 accepted 7-aminoheptanol as substrate as confirmed against the empty vector control (see FIG. 18) and synthesized 7-oxoheptanol as reaction product. Given the reversibility of the .omega.-transaminase activity (see Example 1), it can be concluded that the gene products of SEQ ID Nos: 7, 9 & 10 accept 7-oxoheptanol as substrate and form 7-aminoheptanol.
Example 5
Enzyme activity of -.omega.transaminase using heptamethylenediamine as substrate and forming 7-aminoheptanal
[0232] A nucleotide sequence encoding an N-terminal His-tag was added to the Chromobacterium violaceum, Pseudomonas aeruginosa, Pseudomonas syringae, Rhodobacter sphaeroides, Escherichia coli, and Vibrio fluvialis nucleic acids encoding the .omega.-transaminases of SEQ ID NOs: 7-12, respectively (see FIG. 7) such that N-terminal HIS tagged .omega.-transaminases could be produced. The modified genes were cloned into a pET21a expression vector under the T7 promoter. Each expression vector was transformed into a BL21[DE3] E. coli strain. Each resulting recombinant E. coli strain 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.
[0233] 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.
[0234] Enzyme activity assays in the reverse direction (i.e., heptamethylenediamine to 7-aminoheptanal) were performed in a buffer composed of a final concentration of 50 mM HEPES buffer (pH=7.5), 10 mM heptamethylenediamine, 10 mM pyruvate, and 100 .mu.M pyridoxyl 5' phosphate. Each enzyme activity assay reaction was initiated by adding cell free extract of the .omega.-transaminase gene product or the empty vector control to the assay buffer containing the heptamethylenediamine and then incubated at 25.degree. C. for 4 h, with shaking at 250 rpm. The formation of L-alanine was quantified via RP-HPLC.
[0235] Each enzyme only control without heptamethylenediamine had low base line conversion of pyruvate to L-alanine. See FIG. 13.
[0236] The gene products of SEQ ID NOs: 7-12 accepted heptamethylenediamine as substrate as confirmed against the empty vector control (see FIG. 16) and synthesized 7-aminoheptanal as reaction product. Given the reversibility of the .omega.-transaminase activity (see Example 1), it can be concluded that the gene products of SEQ ID NOs: 7-12 accept 7-aminoheptanal as substrate and form heptamethylenediamine.
Example 6
Enzyme activity of carboxylate reductase for N7-acetyl-7-aminoheptanoate, forming N7-acetyl-7-aminoheptanal

The assays were initiated by adding purified carboxylate reductase and phosphopantetheine transferase or the empty vector control to the assay buffer containing the N7-acetyl-7-aminoheptanoate then incubated at room temperature for 20 min. The consumption of NADPH was monitored by absorbance at 340 nm. Each enzyme only control without N7-acetyl-7-aminoheptanoate demonstrated low base line consumption of NADPH. See FIG. 8.
[0238] The gene products of SEQ ID NO 3, 5, and 6, enhanced by the gene product of sfp, accepted N7-acetyl-7-aminoheptanoate as substrate as confirmed against the empty vector control (see FIG. 11), and synthesized N7-acetyl-7-aminoheptanal.
Example 7
Enzyme activity of .omega.-transaminase using N7-acetyl-1,7-diaminoheptane, and forming N7-acetyl-7-aminoheptanal
[0239] The activity of the N-terminal His-tagged .omega.-transaminases of SEQ ID NOs: 7-12 (see Example 5, and FIG. 7) for converting N7-acetyl-1,7-diaminoheptane to N7-acetyl-7-aminoheptanal was assayed using a buffer composed of a final concentration of 50 mM HEPES buffer (pH=7.5), 10 mM N7-acetyl-1,7-diaminoheptane, 10 mM pyruvate and 100 .mu.M pyridoxyl 5' phosphate. Each enzyme activity assay reaction was initiated by adding a cell free extract of the .omega.-transaminase or the empty vector control to the assay buffer containing the N7-acetyl-1,7-diaminoheptane then incubated at 25.degree. C. for 4 h, with shaking at 250 rpm. The formation of L-alanine was quantified via RP-HPLC.
[0240] Each enzyme only control without N7-acetyl-1,7-diaminoheptane demonstrated low base line conversion of pyruvate to L-alanine. See FIG. 13.
[0241] The gene product of SEQ ID NOs: 7-12 accepted N7-acetyl-1,7-diaminoheptane as substrate as confirmed against the empty vector control (see FIG. 17) and synthesized N7-acetyl-7-aminoheptanal as reaction product.
[0242] Given the reversibility of the .omega.-transaminase activity (see Example 1), the gene products of SEQ ID NOs: 7-12 accept N7-acetyl-7-aminoheptanal as substrate forming N7-acetyl-1,7-diaminoheptane.
Example 8
Enzyme activity of carboxylate reductase using pimelate semialdehyde as substrate and forming heptanedial
[0243] The N-terminal His-tagged carboxylate reductase of SEQ ID NO: 6 (see Example 3 and FIG. 7) was assayed using pimelate semialdehyde as substrate. The enzyme activity assay was performed in triplicate in a buffer composed of a final concentration of 50 mM HEPES buffer (pH=7.5), 2 mM pimelate semialdehyde, 10 mM MgCl.sub.2, 1 mM ATP and 1 mM NADPH. The enzyme activity assay reaction was initiated by adding purified carboxylate reductase and phosphopantetheine transferase or the empty vector control to the assay buffer containing the pimelate semialdehyde and then incubated at room temperature for 20 min. The consumption of NADPH was monitored by absorbance at 340 nm. The enzyme only control without pimelate semialdehyde demonstrated low base line consumption of NADPH. See FIG. 8.
[0244] The gene product of SEQ ID N: 6, enhanced by the gene product of sfp, accepted pimelate semialdehyde as substrate as confirmed against the empty vector control (see FIG. 12) and synthesized heptanedial.
Example 9
Enzyme activity of 4-hydroxybuterate-CoA transferase using 5-ethanamidopentanoic acid as substrate and forming 5-ethanamidopentanoyl-CoA and 7-ethanamido-3-oxoheptanoyl-CoA
[0245] A nucleotide sequence encoding a His-tag was added to the nucleic acid sequences from Cupriavidus necator, Clostridium propionicum, Clostridium aminobutyricum, Citrobacter sp. A1, Acetobacter aceti, and E. coli K12 encoding, in sequential order, the .beta.-ketothiolase, priopionate CoA-transferase, 4-hydroxybuterate-CoA transferase. acetyl-CoA hydrolase, succinyl-CoA: acetate CoA-transferase, and thiolase of SEQ ID NOs: 16, 17, 18, 19, 20, and 21, respectively (see FIG. 7) for production of His-tagged versions of each protein. 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 strain. The resulting recombinant E. coli strains were cultivated at 37.degree. C. in a 500 mL shake flask culture containing 100 mL LB media and antibiotic selection pressure, with shaking at 230 rpm. Each culture was induced overnight at 20.degree. C. using 0.5 mM IPTG.
[0246] The pellet from each induced shake flask culture was harvested via centrifugation. Each pellet was resuspended and lysed via sonication, and the cell debris was separated from the supernatant via centrifugation and passage through a 0.45 .mu.m filter. Each of the His-tagged proteins was purified from the supernatant by Ni-affinity chromatography, diluted 10-fold into 50 mM HEPES buffer (pH=7.5), and concentrated by centrifugal filtration with a cut-off of 10 kD.
[0247] Enzyme assays were performed in two reactions for each of the substrates, N-acetyl-.beta.-alanine (AC5) and 5-ethanamidopentanoic acid (AC7): reaction 1 and reaction 2 (see FIG. 19 for reaction schematic).
[0248] For reaction 1, each enzyme activity assay was performed in a buffer composed of a final concentration of 25 mM HEPES buffer (pH=7.5), 50 mM N-acetyl-.beta.-alanine (AC5) or 50 mM 5-ethanamidopentanoic acic (AC7), and 2 mM acetyl CoA. Each enzyme activity assay was initiated by adding His-tag purified enzymes or the empty vector control to the assay buffer containing either the 50 mM N-acetyl-.beta.-alanine or 5-ethanamidopentanoic acid and incubated at 37.degree. C. for 2 h. The formation of 5-ethanamidopentanoyl-CoA and 7-ethanamido-3-oxoheptanoyl-CoA was monitored by LC-MS to identify products by expected masses at distinct retention times.
[0249] For reaction 2, each enzyme activity assay was performed in a buffer composed of a final concentration of 25 mM HEPES buffer (pH=7.5), 13 mM N-acetyl-.beta.-alanyl-CoA (AC5-CoA) or 2.1 mM 5-ethanamidopentanoyl-CoA (AC7-CoA), and 5 mM acetyl CoA. Each enzyme activity assay was initiated by adding His-tag purified enzymes or the empty vector control to the assay buffer containing either the 50 mM N-acetyl-.beta.-alanine or 5-ethanamidopentanoic acid (AC7-CoA) and incubated at 37.degree. C. for 2 h. The formation of 7-ethanamido-3-oxoheptanoyl-CoA was monitored by LC-MS to identify products by expected masses at distinct retention times.
[0250] The 4-hydroxybuterate-CoA transferase gene product of SEQ ID NO: 18 accepted 5-ethanamidopentanoic acid and 5-ethanamidopentanoyl-CoA as substrate and formed 5-ethanamidopentanoyl-CoA and 7-ethanamido-3-oxoheptanoyl-CoA as products, which was confirmed against the empty vector control. See row for EC 2.8.3- in Table 1, and LC-MS mass peaks confirming product identity by expected mass in FIG. 21 (5-ethanamidopentanoyl-CoA: ESI MS expected [M+H].sup.+=909.2017 and [M+2H].sup.+2=445.1044; found 909.2017 and 445.1042) and FIG. 23 (7-ethanamido-3-oxoheptanoyl-CoA: ESI MS expected [M+H].sup.+=951.2120 and [M+2H].sup.+2=476.1097; found 951.2132 and 476.1091).
