[0005] 2. Description of Related Art

[0006] Gram-negative bacteria possess an outer membrane, with its characteristic asymmetric bilayer as a hallmark. The outer membrane bilayer consists of an inner monolayer containing phospholipids (primarily phosphatidyl ethanolamine) and an outer monolayer that is mainly composed of a single glycolipid, lipopolysaccharide (LPS). There is an immense diversity of LPS structures in the bacterial kingdom and the LPS structure may be modified in response to prevailing environmental conditions. The stability of the LPS layer and interaction between different LPS molecules is mainly achieved by the electrostatic interaction of divalent ions (Mg²+, Ca²+) with the anionic components of the LPS molecule (phosphate groups in the lipid A and the inner core and carboxyl groups of KDO). Furthermore, the dense and ordered packing of the hydrophobic moiety of lipid A, favored by the absence of unsaturated fatty acids, forms a rigid structure with high viscosity. This makes it less permeable for lipophilic molecules and confers additional stability to the outer membrane (OM).

[0007] Various types of agents having bactericidal or bacteriostatic activity are known, e.g. antibiotics, endolysins, antimicrobial peptides and defensins. Increasingly microbial resistance to antibiotics, however, is creating difficulties in treating more and more infections caused by bacteria. Particular difficulties arise with infections caused by Gram-negative bacteria like Pseudomonas aeruginosa and Enterobacteriaceae.

[0008] Endolysins are peptidoglycan hydrolases encoded by bacteriophages (or bacterial viruses). They are synthesized during late gene expression in the lytic cycle of phage multiplication and mediate the release of progeny virions from infected cells through degradation of the bacterial peptidoglycan. They are either β(1,4)-glycosylases (lysozymes), transglycosylases, amidases or endopeptidases. Antimicrobial application of endolysins was already suggested in 1991 by Gasson (GB2243611). Although the killing capacity of endolysins has been known for a long time, the use of these enzymes as antibacterials was ignored due to the success and dominance of antibiotics. Only after the appearance of multiple antibiotic resistant bacteria this simple concept of combating human pathogens with endolysins received interest. A compelling need to develop totally new classes of antibacterial agents emerged and endolysins used as `enzybiotics`--a hybrid term of `enzymes` and `antibiotics`--perfectly met this need. In 2001, Fischetti and coworkers demonstrated for the first time the therapeutic potential of bacteriophage Cl endolysin towards group A streptococci (Nelson et al., 2001). Since then many publications have established endolysins as an attractive and complementary alternative to control bacterial infections, particularly by Gram positive bacteria. Subsequently different endolysins against other Gram positive pathogens such as Streptococcus pneumoniae (Loeffler et al., 2001), Bacillus anthracis (Schuch et al., 2002), S. agalactiae (Cheng et al., 2005) and Staphylococcus aureus (Rashel et al, 2007) have proven their efficacy as enzybiotics. Nowadays, the most important challenge of endolysin therapy lies in the insensitivity of Gram-negative bacteria towards the exogenous action of endolysins, since the outer membrane shields the access of endolysins from the peptidoglycan. This currently prevents the expansion of the range of effective endolysins to important Gram-negative pathogens.

[0009] Antimicrobial peptides (AMPs) represent a wide range of short, cationic or amphipatic, gene encoded peptide antibiotics that can be found in virtually every organism. Different AMPs display different properties, and many peptides in this class are being intensively researched not only as antibiotics, but also as templates for cell penetrating peptides. Despite sharing a few common features (e.g., cationicity, amphipathicity and short size), AMP sequences vary greatly, and at least four structural groups (α-helical, β-sheet, extended and looped) have been proposed to accommodate the diversity of the observed AMP conformations. Likewise, several modes of action as antibiotics have been proposed, and it was shown e.g. that the primary target of many of these peptides is the cell membrane whereas for other peptides the primary target is cytoplasmic invasion and disruption of core metabolic functions. AMPs may become concentrated enough to exhibit cooperative activity despite the absence of specific target binding; for example, by forming a pore in the membrane, as is the case for most AMPs. However, this phenomenon has only been observed in model phospholipid bilayers, and in some cases, AMP concentrations in the membrane that were as high as one peptide molecule per six phospholipid molecules were required for these events to occur. These concentrations are close to, if not at, full membrane saturation. As the minimum inhibitory concentration (MIC) for AMPs are typically in the low micromolar range, scepticism has understandably arisen regarding the relevance of these thresholds and their importance in vivo (Melo et al., Nature reviews, Microbiology, 2009, 245).

[0010] Defensins are a large family of small, cationic, cysteine- and arginine-rich antimicrobial peptides, found in both vertebrates and invertebrates. Defensins are divided into five groups according to the spacing pattern of cysteines: plant, invertebrate, α-, β-, and θ-defensins. The latter three are mostly found in mammals. α-defensins are proteins found in neutrophils and intestinal epithelia. β-defensins are the most widely distributed and are secreted by leukocytes and epithelial cells of many kinds. θ-defensins have been rarely found so far e.g. in leukocytes of rhesus macaques. Defensins are active against bacteria, fungi and many enveloped and nonenveloped viruses. However, the concentrations needed for efficient killing of bacteria are mostly high, i.e. in the micromolar range. Activity of many peptides may be limited in presence of physiological salt conditions, divalent cations and serum. Depending on the content of hydrophobic amino acid residues defensins also show haemolytic activity.

[0019] The term "protein" as used herein refers synonymously to the term "polypeptide". The term "protein" as used herein refers to a linear polymer of amino acid residues linked by peptide bonds in a specific sequence. The amino-acid residues of a protein may be modified by e.g. covalent attachments of various groups such as carbohydrates and phosphate. Other substances may be more loosely associated with the polypeptide chains, such as heme or lipid, giving rise to the conjugated proteins which are also comprised by the term "protein" as used herein. The various ways in which the polypeptide chains fold have been elucidated, in particular with regard to the presence of alpha helices and beta-pleated sheets. The term "protein" as used herein refers to all four classes of proteins being all-alpha, all-beta, alpha/beta and alpha plus beta.

[0020] The term "fusion protein" as used herein refers to an expression product resulting from the fusion of two nucleic acid sequences. Such a protein may be produced, e.g., in recombinant DNA expression systems. Moreover, the term "fusion protein" as used herein refers to a fusion of a first amino acid sequence as e.g. an endolysin, with a second or further amino acid sequence. The second or further amino acid sequence is preferably a peptide stretch, in particular a cationic peptide, a polycationic peptide, an amphipatic peptide, a sushi peptide, a defensin, a hydrophobic peptide or an antimicrobial peptide. Preferably, said second and/or further amino acid sequence is foreign to and not substantially homologous with any domain of the first amino acid sequence.

[0021] The term "peptide stretch" as used herein refers to any kind of peptide linked to a protein such as an endolysin. In particular the term "peptide stretch" as used herein refers to a cationic peptide, a polycationic peptide, an amphipatic peptide, a sushi peptide, a defensin, a hydrophobic peptide and/or an antimicrobial peptide.

The term "tag" in contrast to the term "peptide stretch" as used herein refers to a peptide which can be useful to facilitate expression and/or affinity purification of a polypeptide, to immobilize a polypeptide to a surface or to serve as a marker or a label moiety for detection of a polypeptide e.g. by antibody binding in different ELISA assay formats as long as the function making the tag useful for one of the above listed facilitation is not caused by the positively charge of said peptide. However, the His₆-tag may, depending on the respective pH, also be positively charged, but is used as affinity purification tool as it binds to immobilized divalent cations and is not used as a peptide stretch according to the present invention.

[0022] The term "peptide" as used herein refers to short polypeptides consisting of from about 2 to about 100 amino acid residues, more preferably from about 4 to about 50 amino acid residues, more preferably from about 5 to about 30 amino acid residues, wherein the amino group of one amino acid residue is linked to the carboxyl group of another amino acid residue by a peptide bond. A peptide may have a specific function. A peptide can be a naturally occurring peptide or a synthetically designed and produced peptide. The peptide can be, for example, derived or removed from a native protein by enzymatic or chemical cleavage, or can be prepared using conventional peptide synthesis techniques (e.g., solid phase synthesis) or molecular biology techniques (see Sambrook, J. et al., Molecular Cloning: A Laboratory Manual, Cold Spring Harbor Press, Cold Spring Harbor, N.Y. (1989)). Preferred naturally occurring peptides are e.g. antimicrobial peptides, defensins, and sushi peptides. Preferred synthetically produced peptides are e.g. polycationic, amphiphatic or hydrophobic peptides.

In addition, the endolysins may contain also regions which are enzymatically inactive, and bind to the cell wall of the host bacteria, the so-called CBDs (cell wall binding domains). The endolysin may contain two or more CBDs. However, the term "endolysin" as used herein refers also to enzymes having at least one EAD but no CBDs. Generally, the cell wall binding domain is able to bind different components on the surface of bacteria. Preferably, the cell wall binding domain is a peptidoglycan binding domain and binds to the bacteria's peptidoglycan structure. The different domains of an endolysin can be connected by a domain linker.

[0024] The term "domain linker" as used herein refers to an amino acid sequence functioning to connect single protein domains with one another. As a rule domain linkers form no or only few regular secondary structure like α-helices or β-sheets and can occupy different conformations with the respective structural context.

[0029] The term "cell wall" as used herein refers to all components that form the outer cell enclosure of the Gram-negative bacteria and thus guarantee their integrity. In particular, the term "cell wall" as used herein refers to peptidoglycan, the outer membrane of the Gram-negative bacteria with the lipopolysaccharide, the bacterial cell membrane, but also to additional layers deposited on the peptidoglycan as e.g. capsules, outer protein layers or slimes.

[0030] The term "EAD" as used herein refers to the enzymatically active domain of an endolysin. The EAD is responsible for hydrolysing bacterial peptidoglycans.

The term "cationic peptide" as used herein refers also to polycationic peptides.

[0032] The term "polycationic peptide" as used herein refers to a synthetically produced peptide composed of mostly positively charged amino acid residues, in particular lysine and/or arginine residues. A peptide is composed of mostly positively charged amino acid residues if at least about 20, 30, 40, 50, 60, 70, 75, 80, 85, 90, 95 or about 100% of the amino acid residues are positively charged amino acid residues, in particular lysine and/or arginine residues.

The term "defensins" as used herein refers both to an isolated form from animal cells or to a synthetically produced form, and refers also to variants which substantially retain the cytotoxic activities of their parent proteins, but whose sequences have been altered by insertion or deletion of one or more amino acid residues.

[0035] The term "sushi peptide" as used herein refers to complement control proteins (CCP) having short consensus repeats. The sushi module of sushi peptides functions as a protein-protein interaction domain in many different proteins. Peptides containing a Sushi domain have been shown to have antimicrobial activities.

[0036] The term "amphipathic peptide" as used herein refers to peptides having both hydrophilic and hydrophobic functional groups. Preferably, the term "amphipathic peptide" as used herein refers to a peptide having a defined arrangement of hydrophilic and hydrophobic groups e.g. amphipatic peptides may be e.g. alpha helical, having predominantly non polar side chains along one side of the helix and polar residues along the remainder of its surface.

[0037] The term "hydrophobic group" as used herein refers to chemical groups such as amino acid side chains which are substantially water insoluble, but soluble in an oil phase, with the solubility in the oil phase being higher than that in water or in an aqueous phase. In water, amino acid residues having a hydrophobic side chain interact with one another to generate a nonaqueous environment. Examples of amino acid residues with hydrophobic side chains are valine, isoleucine, leucine, methionine, phenylalanine, tryptophan, cysteine, alanine, tyrosine, histidine, threonin, serine, proline and glycine residues.

[0038] The present invention relates to new antibacterial agents against Gram-negative bacteria. In particular the present invention relates to a polypeptide comprising an amino acid sequence according to SEQ ID NO: 1 or fragments or derivatives thereof. The polypeptide comprising an amino acid sequence according to SEQ ID NO: 1 is preferably encoded by a nucleotide sequence according to SEQ ID NO: 3.

The degradation of the bacterial cells by the polypeptide, fragment, derivative and/or fusion protein according to the present invention can be supported by the addition of detergents like Triton X-100 or other additives which weaken the bacterial cell envelope like polymyxin B. Specific cell degradation is needed as an initial step for subsequent specific detection of bacteria using nucleic acid based methods like PCR, nucleic acid hybridization or NASBA (Nucleic Acid Sequence Based Amplification), immunological methods like IMS, immunofluorescence or ELISA techniques, or other methods relying on the cellular content of the bacterial cells like enzymatic assays using proteins specific for distinct bacterial groups or species (e.g. β-galactosidase for enterobacteria, coagulase for coagulase positive strains).

[0088] In a further aspect the present invention relates to the use of the polypeptide, fragment, derivative and/or fusion protein according to the present invention for the treatment or prevention of Gram-negative bacterial contamination of foodstuff, of food processing equipment, of food processing plants, of surfaces coming into contact with foodstuff such as shelves and food deposit areas and in all other situations, where pathogenic, facultative pathogenic or other undesirable bacteria can potentially infest food material, of medical devices and of all kind of surfaces in hospitals and surgeries.

[0089] In particular, a polypeptide, fragment, derivative and/or fusion protein of the present invention may be used prophylactically as sanitizing agent. Said sanitizing agent may be used before or after surgery, or for example during hemodialysis. Moreover, premature infants and immunocompromised persons, or those subjects with need for prosthetic devices may be treated with a fusion protein according to the present invention. Said treatment may be either prophylactically or during acute infection. In the same context, nosocomial infections, especially by antibiotic resistant strains like Pseudomonas aeruginosa (FQRP), Acinetobacter species and Enterobacteriaceae such as E. coli, Salmonella, Shigella, Citrobacter, Edwardsiella, Enterobacter, Hafnia, Klebsiella, Morganella, Proteus, Providencia, Serratia and Yersinia species may be treated prophylactically or during acute phase with a polypeptide, fragment, derivative and/or fusion protein of the present invention. Therefore, a polypeptide, fragment, derivative and/or fusion protein according to the present invention may be used as a disinfectant also in combination with other ingredients useful in a disinfecting solution like detergents, tensids, solvents, antibiotics, lantibiotics, or bacteriocins.

[0090] The following examples explain the present invention but are not considered to be limiting. Unless indicated differently, molecular biological standard methods were used, as e.g., described by Sambrock et al., 1989, Molecular Cloning: A Laboratory Manual, 2nd edition, Cold Spring Harbor Laboratory Press, Cold Spring Harbor, New York.

EXAMPLE 1

Modified Endolysin Variants of Pseudomonas putida Phage OBP

[0091] OBPgpLYS having an amino acid sequence according to SEQ ID NO: 1 is a modular endolysin of 332 amino acid residues originating from Pseudomonas putida phage OBP with a putative N-terminal peptidoglycan binding domain and a C-terminal catalytic chitinase domain. OPBgpLYS having an amino acid sequence according to SEQ ID NO: 47 comprises in comparison to OBPgpLYS having an amino acid sequence according to SEQ ID NO: 1 an additional C-terminal His₆-tag linked to the C-terminus by the additional amino acid residues lysin and glycin (Lys-Gly)

[0092] Purified genomic DNA of phage OBP was used as a template for the amplification of the open reading frame (ORF) of OBPgpLYS in standard PCR reaction with Pfu polymerase (Fermentas, Ontario, Canada) using the following PCR parameters:

##STR00001##

[0093] Therefore a standard 5' primer (5' ATGAAAAATAGCGAGAAGAAT 3' (SEQ ID NO: 44)) and a standard 3' primer (5' AACTATTCCGAGTGCTTTCTTTGT 3' (SEQ ID NO: 45)) was used. To extend the 5' end of the ORF which encodes OBPgpLYS with a gene fragment encoding the polycationic 9-mer peptide Lys-Arg-Lys-Lys-Arg-Lys-Lys-Arg-Lys- (SEQ ID NO: 20) a tail PCR (with same parameters as standard PCR above) with an extended 5' primer (5' ATGGGATCCAAACGCAAGAAACGTAAGAAACGCAAAAAAAATAGCGAG AAGAAT 3' (SEQ ID NO: 46)) and the standard 3' primer according to SEQ ID NO: 45 was applied. Both the original unmodified OBPgpLYS PCR fragment and the extended fragment were ligated in the pEXP5CT/TOPO® expression vector (Invitrogen, Carlsbad, Calif., USA) by following the TA-cloning protocol of the manufacturer.

[0094] Recombinant expression of OBPgpLYS having an amino acid sequence according to SEQ ID NO: 47 and PKOBPgpLYS having an amino acid sequence according to SEQ ID NO: 49 is performed in exponentially growing E. coli BL21 (λDE3) pLysS cells (Invitrogen) after induction with 1 mM IPTG (isopropylthiogalactoside) at 37° C. for a period of 4 hours. Both proteins were purified by Ni²+ affinity chromatography (Akta FPLC, GE Healthcare) using the C-terminal 6xHis-tag, encoded by the pEXP5CT/TOPO® expression vector. The Ni²+ affinity chromatography is performed in 4 subsequent steps, all on room temperature:

[0095] 1. Equilibration of the Histrap HP 1 ml column (GE Healthcare) with 10 column volumes of Washing Buffer (60 mM imidazole, 0.5 mM NaCl and 20 mM NaH₂PO₄--NaOH on pH 7.4) at a flow rate of 0.5 ml/min.

[0096] 2. Loading of the total lysate (with wanted endolysin) on the Histrap HP 1 ml column at a flow rate of 0.5 ml/min.

[0097] 3. Washing of the column with 15 column volumes of Washing Buffer at a flow rate of 1 ml/min.

[0098] 4. Elution of bounded endolysin from the column with 10 column volumes of Elution Buffer (500 mM imidazole, 0.5 M NaCl and 20 mM NaH₂PO₄--NaOH on pH 7.4) at a flow rate of 0.5 ml/min

[0099] The total yields of both purified recombinant proteins per liter E. coli expression culture is shown in Table 1. The values were determined by spectrophotometric measurement of the protein concentration and the total volume of the purified stock solution at a wavelength of 280 nm. Purified stock solutions consisting of OBPgpLYS and PKOBPgpLYS, respectively, in Elution Buffer (20 mM NaH₂PO₄--NaOH pH7.4; 0.5 M NaCl; 500 mM imidazole) were at least 90% pure as determined visually on SDS-PAGE gels.

[0100] To determine the anti-Gram-negative spectrum of the endolysins OBPgpLYS according to SEQ ID NO: 47 and PKOBPgpLYS according to SEQ ID NO: 49, a combination of 1.313 μM of each endolysin and 0.5 mM EDTA was tested on the clinical multiresistant P. aeruginosa strain Br667, Pseudomonas putida G1 (host of phage OBP) and a range of other Gram-negative pathogens (P. aeruginosa PAO1p, P. aeruginosa Br667, P. putida G1, Burkholderia pseudomallei, Escherichia coli WK6 and Salmonella typhimurium) (see Table 3). Exponential growing bacterial cells (OD₆₀₀ nm of 0.6) were 100-fold diluted to a final density of about 10⁶ cells/ml of each strain was incubated for 30 minutes at room temperature without shaking with unmodified endolysin OBPgpLYS (SEQ ID NO: 47) and modified endolysin PKOBPgpLYS (SEQ ID NO: 49) each in combination without and with 0.5 mM EDTA. For incubation, the endolysins were used each in buffer (20 mM NaH₂PO₄--NaOH pH 7.4; 0.5 M NaCl; 0.5 M imidazole) and the incubation took place at a final concentration of endolysin of 1,313 μM. As a control each strain was also incubated for 30 minutes with 0.5 mM EDTA (in same buffer as outlined above) but no endolysin. After incubation cell suspensions were diluted three times (respectively 10⁵-10⁴-10.sup.3 cells/ml) and 100 μl of each dilution was plated out on LB-medium. The residual colonies were counted after an overnight incubation at 37° C. Based on the counted cell numbers the antibacterial activity as the relative inactivation in logarithmic units (=log₁₀N₀/N_i with N₀=number of untreated cells and N_i=number of treated cells, both counted after incubation) was calculated (Table 2). All samples were replicated in threefold. Averages +/- standard deviations are represented. The maximal reduction observed is dependent on the detection level of 10 cells/ml and the initial cell density.

[0101] While the global efficacy of the OBPgpLYS treatment is species dependent, the results in Table 2 show an added effect of the PKOBPgpLYS compared to unmodified OBPgpLYS for all bacterial species tested, both in the absence as the presence of 0.5 mM EDTA. For Pseudomonas and Burkholderia species, a clear synergistic effect with EDTA is observed for the PKOBPgpLYS activity.

EXAMPLE 2

Effect of Different EDTA Concentrations on the Antibacterial Activity of OBPgpLYS and PKOBPgpLYS

[0102] To determine the influence of EDTA on the antibacterial activity of unmodified and modified endolysins the antibacterial activity of the unmodified OBPgpLYS endolysin (SEQ ID NO: 47) and the PKOBPgpLYS endolysin (SEQ ID NO: 49) was tested on Pseudomonas aeruginosa PAO1p cells (Pirnay J P et al. J Clin Microbiol., 41(3):1192-1202 (2003)) using different concentrations of EDTA and endolysins. Exponential growing bacterial cells (OD₆₀₀ nm of 0.6) were 100-fold diluted to a final density of about 10⁶ cells/ml and incubated for 30 minutes at room temperature without shaking with unmodified endolysin OBPgpLYS (SEQ ID NO: 47) and modified endolysin PKOBPgpLYS (SEQ ID NO: 49). For incubation, the endolysins were used each in buffer (20 mM NaH₂PO₄--NaOH pH 7.4; 0.5 M NaCl; 0.5 M imidazole) at final concentrations of endolysin of 0.013 μM, 0.131 μM and 1.315 μM. Thereby, the following different EDTA concentrations were used: 0 mM, 0.05 mM, 0.5 mM and 10 mM. As a control one sample was also incubated for 30 minutes with no endolysin, instead of there was buffer (20 mM NaH₂PO₄--NaOH pH 7.4; 0.5 M NaCl; 0.5 M imidazole) added. After incubation cell suspensions were diluted three times (respectively 10⁵-10⁴-10.sup.3 cells/ml) and 100 μl of each dilution was plated out on LB-medium. The residual colonies were counted after an overnight incubation at 37° C. Based on the counted cell numbers the antibacterial activity as the relative inactivation in logarithmic units (=log₁₀N₀/N_i with N₀=number of untreated cells and N_i=number of treated cells, both counted after incubation) was calculated (Table 4). All samples were replicated in threefold. Averages +/- standard deviations are represented. The maximal reduction observed (5.69 log units) is dependent on the detection level of 10 cells/ml and the initial cell density. "Δ" gives the difference of activity between the respective OBPgpLYS and PKOBPgpLYS samples.

TABLE-US-00008 TABLE 4 Antibacterial activity of unmodified endolysin (OBPgpLYS) and its modified endolysin variant (PKOBPgpLYS) in combination with different EDTA-Na₂ concentrations on exponential growing Pseudomonas aeruginosa PAO1p cells in logarithmic units Concentration of EDTA-Na₂ (in mM) 0 0.05 0.5 10 No endolysin / 0.028 +/- 0.008 0.130 +/- 0.023 1.827 +/- 0.052 0.013 μM OBPgpLYS 0.956 +/- 0.110 / 4.626 +/- 0.287 / 0.013 μM 0.992 +/- 0.181 / 5.204 +/- 0.000 / PKOBPgpLYS Δ 0.036 0.578 0.131 μM OBPgpLYS 2.158 +/- 0.027 / 4.599 +/- 0.275 / 0.131 μM 2.529 +/- 0.184 / 5.671 +/- 0.000 / PKOBPgpLYS Δ 0.371 1.072 1.315 μM OBPgpLYS 2.531 +/- 0.173 2.762 +/- 0.091 4.357 +/- 1.857 4.888 +/- 0.275 1.315 μM 3.079 +/- 0.015 4.145 +/- 0.015 >5.687 >5.687 PKOBPgpLYS Δ 0.548 1.383 >1.330 >0.799

[0103] As shown in Table 4 unmodified endolysin OBPgpLYS reduces cell numbers significantly with more than 2.5 log units for 1.315 μM and with +/-1 log unit for 0.013 μM, compared to the negative control. Modified endolysin PKOBPgpLYS results in an added 0.5 log units reduction for exponentially growing PAO1p cells. The observed antibacterial effect can be increased to more as 5.69 log units reduction (beneath the detection level) by combining PKOBPgpLYS with the outer membrane permeabilizer EDTA-Na₂ at a concentration of 0.5 and 10 mM EDTA. The difference in activity between the unmodified OBPgpLYS and the PK-modified OBPgpLYS increases by raising the amount of added endolysin (from 0.013-1.315 μM endolysin).

EXAMPLE 3

Cloning, Expression and Purification of an OBPgpLYS Derivative Modified with Various Peptide Stretches on the N-terminus of the Endolysin

[0104] The OBPgpLYS derivative according to SEQ ID NO:86 is a modular endolysin originating from Pseudomonas putida phage OBP with an N-terminal peptidoglycan binding and C-terminal catalytic domain. The OBPgpLYS derivative is encoded by the nucleic acid molecule according to SEQ ID NO: 101. Purified Plasmid DNA (see Example 1) was used to produce a nucleic acid molecule according to SEQ ID NO: 101 with a BamH I (5'-GGA TCC-3') restriction site at the 5'-end of the nucleic acid molecule and an Xho I (5'-CTC GAG-3') restriction site at the 3'-end of the nucleic acid molecule.

[0105] The following peptide stretches in table 5 were used for production of fusion proteins with the endolysin OBPgpLYS derivative. The resulting fusion proteins are also listed in table 5.

TABLE-US-00009 TABLE 5 Peptide stretches and their respective nucleic acid sequence for production of specific fusion proteins Nucleic acid molecule Amino acid encoding the peptide sequence of Peptide stretch stretch resulting fusion protein Ascaphine SEQ ID NO: 90 SEQ ID NO: 55 (SEQ ID NO: 50) Apidaecine SEQ ID NO: 91 SEQ ID NO: 57 (SEQ ID NO: 51) Sarcotoxin IA SEQ ID NO: 92 SEQ ID NO: 63 (SEQ ID NO: 17) SMAP-29 SEQ ID NO: 93 SEQ ID NO: 65 (SEQ ID NO: 12) Cecropin A (A. aegypti) SEQ ID NO: 94 SEQ ID NO: 67 (SEQ ID NO: 15)

[0106] The nucleic acid molecules encoding the respective peptide stretches were synthetically produced with a Nde I (5'-CAT ATG-3') restriction site at the 5'-end of the nucleic acid molecule and a BamH I (5'-GGA TCC-3') restriction site at the 3'-end of the nucleic acid molecule.

[0107] Fusion proteins are constructed by linking at least two nucleic acid sequences using standard cloning techniques as described e.g. by Sambrook et al. 2001, Molecular Cloning: A Laboratory Manual. Therefore the nucleic acid molecules encoding the peptide stretches were cleaved in a digest with the respective restriction enzymes Nde I and BamH I. Subsequently the cleaved nucleic acids encoding the peptide stretches were ligated into the pET21 b expression vector (Novagen, Darmstadt, Germany), which was also cleaved in a digest with the respective restriction enzymes Nde I and BamH I before.

[0108] Afterwards, the nucleic acid molecule encoding the endolysin OBPgpLYS derivative was cleaved in a digest with the restriction enzyme BamH I and Xho I, so that the endolysin could be ligated into the pET21b expression vector (Novagen, Darmstadt, Germany).

[0109] Thus, the nucleic acid molecule encoding the peptide stretch is ligated into the respective vector at the 5'-end of the nucleic acid molecule encoding the endolysin OBPgpLYS derivative. Moreover, the nucleic acid molecule encoding the endolysin OBPgpLYS derivative is ligated into the respective plasmid, so that a nucleic acid molecule encoding a His₆-tag consisting of six histidine residues is associated at the 3'-end of the nucleic acid molecule encoding the endolysin.

[0110] The sequence of the endolysin-peptide-fusions was controlled via DNA-sequencing and correct clones were transformed into E. coli T7 Express lysY/Iq (New England Biolabs, Frankfurt, Germany) for protein expression.

[0111] Recombinant expression of the fusion proteins according to SEQ ID NO: 55, 57, 63, 65, 67 is performed in E. coli T7 Express lysY/Iq (New England Biolabs, Frankfurt, Germany). The cells were growing until an optical density of OD600 nm of 0.5-0.8 was reached. Then the expression of the fusion protein was induced with 0.5 mM IPTG (isopropylthiogalactoside) and the expression was performed at 37° C. for a period of 4 hours.

[0112] Cells were harvested by centrifugation for 15 min at 4000 g and disrupted via sonication on ice. Soluble and insoluble fraction of the E. coli crude extract were separated by centrifugation (Sorvall, SS34, 30 min, 15000 rpm). All proteins were purified by Ni²+ affinity chromatography (Akta FPLC, GE Healthcare) using the C-terminal 6xHis-tag, encoded by the pET21b vector.

[0113] The Ni²+ affinity chromatography is performed in 4 subsequent steps, all at room temperature:

[0114] 1. Equilibration of the Histrap FF 5 ml column (GE Healthcare) with up to 10 column volumes of Washing Buffer (20 mM imidazole, 1 M NaCl and 20 mM Hepes on pH 7.4) at a flow rate of 3-5 ml/min.

[0115] 2. Loading of the total lysate (with wanted fusion protein) on the Histrap FF 5 ml column at a flow rate of 3-5 ml/min.

[0116] 3. Washing of the column with up to 10 column volumes of Washing Buffer to remove unbound sample followed by a second washing step with 10% Elution buffer (500 mM imidazole, 0.5 M NaCl and 20 mM Hepes on pH 7.4) at a flow rate of 3-5 ml/min.

[0117] 4. Elution of bounded fusion proteins from the column with a linear gradient of 4 column volumes of Elution Buffer (500 mM imidazole, 0.5 M NaCl and 20 mM Hepes on pH 7.4) to 100% at a flow rate of 3-5 ml/min.

[0118] Purified stock solutions of fusion proteins in Elution Buffer (20 mM Hepes pH 7.4; 0.5 M NaCl; 500 mM imidazole) were at least 60% pure as determined visually on SDS-PAGE gels (data not shown).

Overnight cultures were diluted 10-fold in fresh LB medium and grown to OD₆₀₀=0.6. The culture was spun down and diluted 10-fold in dilution buffer (10 mM HEPES, 0.5 mM EDTA; pH 7.4). Bacteria were incubated at room temperature with each 10 μg undialyzed fusion protein at a final concentration of 100 μg/ml in buffer (20 mM NaH₂PO₄--NaOH pH 7.4; 0.5 M NaCl; 0.5 M imidazole). After 1 hour cell dilution series were made in PBS and plated on LB. Additionally, a negative control was plated using buffer (20 mM NaH₂PO₄--NaOH pH 7.4; 0.5 M NaCl; 0.5 M imidazole). The residual colonies were counted after an overnight incubation at 37° C. Based on the counted cell numbers the antibacterial activity as logarithmic units (=log₁₀N₀/N_i with N₀=number of untreated cells and N_i=number of treated cells) was calculated (Table 5). All samples were replicated at least in four fold.

Methodology of Tag Modification of the OBPgpLys Derivative

[0122] Except for the pentapeptide tag, all antibacterial peptide tags were fused to the ORF which encodes for the OBPgpLYS derivative using an adapted version of the Ligation Independent Cloning (LIC) as e.g. described in Berrow et al. 2007. Here fore, an unique Ecl136II restriction site was inserted in front of the WT endolysin gene by a tail PCR with a specific designed 5' primer (5'-GGAATGGGGAGCTCCTCCAAAAATAGCGAGAAG-3'; SEQ ID NO:102) and the standard OBPgpLys derivative reverse primer (5'-AACTATTCCGTGTGCTTTCTTTGT -3'; SEQ ID NO:103) on pure genomic DNA of phage OBP. This extended fragment was then ligated in the pEXP5CT/TOPO® expression vector (Invitrogen, Carlsbad, Calif., USA) by following the TA cloning protocol of the manufacturer. Pure plasmid was cutted once in an Ecl136II restriction digest and hybridized peptide cassettes (created by hybridization of primer pairs, see Table 8) were inserted into the cutted plasmid without a necessary ligation step (LIC). For the N-terminal pentapeptide tag fusion a tail PCR with an extended 5' primer which encodes for this pentapeptide (5' -ATGGGATCCTTCTTCGTAGCA CCGGGCTCCTCCAAAAATAGCGAGAAG-3'; SEQ ID NO:104) and the standard OBPgpLys derivative reverse primer (5'-AACTATTCCGTGTGCTTTCTTTGT-3'; SEQ ID NO:103) was applied on phage OBP genomic DNA. Correct insertion of the fragments in the expression vector was verified by sequencing analysis before introducing the construct into a suitable Escherichia coli BL21(DE3)pLysS expression strain.

Large Scale Recombinant Expression of Modified OBPgpLYS Derivative Fusion Variants

[0123] Standard expression is performed in Lysogeny Broth (LB) in exponentially growing cells (OD600 nm=0.6) induced with 1 mM isopropyl-beta-D-thiogalactopyranoside. Expression parameters like temperature, time and expression strain varied on a protein specific basis in order to optimize the soluble expression levels of the modified endolysins (see Table 9).

[0124] For purification, cells from an expression culture (500-600 ml) are harvested (4500 rpm, 30 min, 4° C.) and resuspended in 1/25 volumes of lysis buffer (10 mM imidazole, 20 mM NaH2PO4, 0.5 M NaCl, pH 7.4). This suspension is frozen/thawed three times prior to sonication (8×30 s, amplitude 40% on a Vibra Cell®, Sonics, Dandurry, Conn., USA) and filtered through 0.45 and 0.22 μm Durapore membrane filters (Millipore, Billerica, Mass., USA). Purification of the His-tagged fusion protein was performed by a one-step protocol employing Ni2+-affinity chromatography (HisTrap HP 1 ml column, GE Healthcare, Buckinghamshire, UK) according to the manufacturer's instructions. The Ni2+ affinity chromatography is performed in 4 subsequent steps, all on room temperature:

[0125] 1. Equilibration of the Histrap HP 1 ml column (GE Healthcare) with 10 column volumes of Washing Buffer (60 mM imidazole, 0.5 mM NaCl and 20 mM NaH2PO4--NaOH on pH 7.4) at a flow rate of 0.5 ml/min.

[0126] 2. Loading of the total lysate (with wanted endolysin) on the Histrap HP 1 ml column at a flow rate of 0.5 ml/min.

[0127] 3. Washing of the column with 15 column volumes of Washing Buffer at a flow rate of 1 ml/min.

[0128] 4. Elution of bounded endolysin from the column with 10 column volumes of Elution Buffer (500 mM imidazole, 0.5 M NaCl and 20 mM NaH2PO4--NaOH on pH 7.4) at a flow rate of 0.5 ml/min

[0129] The wash buffer included a low imidazole concentration which varied on protein specific base to ensure higher purity of the protein (see Table 9). The total yields of recombinant proteins per liter E. coli expression culture is also shown in Table 3. The values were determined by spectrophotometric measurement of the protein concentration and the total volume of the purified stock solution at a wavelength of 280 nm. Purified stock solutions were at least 60% pure as determined visually on SDS-PAGE gels.

In Vitro Antibacterial Activity and Host Range of Modified OBPgpLys Derivative Variants

[0130] Exponential growing Gram-negative bacterial cells (OD600 nm=0.6) were 100-fold diluted to a final density of about 106 cells/ml and incubated for 30 minutes at room temperature without shaking with the different modified OBPgpLYS derivative variants. After incubation cell suspensions were diluted three times (respectively 105-104-103 cells/ml) and 100 μl of each dilution was plated out on LB-medium. The residual colonies were counted after an overnight incubation on 37° C. Based on the counted cell numbers the antibacterial activity as the relative inactivation in logarithmic units (=log10N₀/N_i with N₀=number of untreated cells and N_i=number of treated cells, both counted after incubation) is calculated (Table 10). All samples were replicated in threefold. Averages +/- standard deviations are represented.

Initial density is 10⁶ cells/ml and incubation proceeds for 30 minutes without shaking at RT. Protein concentration is 1500 nM, except for Artilys1-OBPgplys (800 nM).
