Definitions

  • the present invention describes the cloning and expression of a lipase gene in combination with a lipase modulator gene, both obtained from a class I Pseudomonas species, in an homologous class I Pseudomonas species.
  • Lipases are enzymes capable of hydrolyzing lipids they are utilized in a wide range of applications such as fats and oil processing, detergents, diagnostic reagents etc.
  • Extracellular lipases (triacylglycerol acylhydrolases, E.C. 3.1.1.3) are produced by a wide variety of micro- organisms. Suitable microbial lipases have for example been disclosed in U.S. Patent No. 3,950,277, these lipases were obtained from such diverse microorganisms as Pseudomonas. Asper ⁇ illus. Pneumococcus. Staphylococcus. ycobacterium tuberculosis. Mycotorula lipolytica and Sclerotinia. It has turned out that especially Pseudomonas lipases have favourable characteristics for the desired applications. Pseudomonas species have therefore been extensively used for obtaining lipases.
  • EP 331376 describes the cloning and expression of a lipase gene obtained from Pseudomonas cepacia in P. cepacia. It was found that no expression could be obtained when a second gene located downstream of the lipase gene was deleted. This gene was therefore reported to be essential for lipase production.
  • EP 464922 reports the cloning and expression of a lipase gene together with a gene encoding a protein reported to have a lipase-specific stabilizing/translocation function. The genes are obtained from Pseudomonas qlumae and expression is preferably in heterologous systems. The stabilising protein is reported to differ greatly from the gene described in EP 331376 and therefor assumed to have a different function.
  • WO 91/00908 reports the expression in a heterologous host of the lipase gene and the lipase modulator gene obtained from P. cepacia.
  • Lipase modulator genes are reported to be essential for obtaining lipase production, however for an extensively investigated representative of class I Pseudomonas species: Pseudomonas fraqi such a gene was not found. Another class I Pseudomonas lipase gene was described in EP 334462.
  • EP 334462 reports the cloning and expression of the lipase gene from Pseudomonas pseudoalcaliqenes in E. coli it can be concluded that for heterologous lipase production the lipase modulator gene was not essential.
  • the classification of Pseudomonas species is based on DNA-rRNA and DNA-DNA hybridization studies as reported by Palleroni et al.
  • the present invention discloses a lipase modulator gene and the corresponding protein obtained from a class I Pseudomonas species.
  • the present invention also discloses Pseudomonas strains which have been transformed with a DNA sequence encoding a lipase and a sequence encoding a lipase modulator gene. These strains are preferably class I Pseudomonas strains and more preferably Pseudomonas pseudoalcaliqenes strains. The present invention further discloses a method for obtaining such transformed strains.
  • the invention further discloses a vector derived from pJRD215 and which is segregationally stable in Pseudomonas. A method for obtaining such a vector is also disclosed.
  • Km r gene encoding neo ycin resistance of Tn5.
  • lip gene encoding Ml lipase. Furthermore a number of restriction sites are indicated. - 4 -
  • Figure 2 Sequence of pJRD215 (derived from Davison et al.
  • Km r gene encoding neomycin resistance of Tn5.
  • lip gene encoding Ml lipase. Due to the deletion plasmid PlA ⁇ is about 900 bp smaller than P1A, also several restriction sites are missing.
  • Figure 4 Construction and restriction map of plasmid PIB.
  • Plasmid pTMPvl ⁇ A was described in EP 334462.
  • lip gene encoding Ml lipase, location indicated by an arrow Tc r : gene encoding tetracyclin resistance.
  • Km r gene encoding neomycin resistance of Tn5.
  • lip gene encoding Ml lipase.
  • lim gene encoding the Ml lipase modulator protein.
  • Figure 6 Restriction map of plasmid P24B.
  • lip gene encoding Ml lipase, location indicated by an arrow lim: gene encoding the Ml lipase modulator protein, location also indicated by an arrow.
  • the recombinant DNA of the present invention is obtained by digestion of chromosomal DNA obtained from a strain of a Pseudomonas class I species.
  • Representatives of class I Pseudomonas species are: Pseudomonas alcaligenes. Pseudomonas pseudoalcaligenes. Pseudomonas stutzeri. Pseudomonas aeruginosa. and Pseudomonas mendocina.
  • the chromosomal DNA is isolated using standard procedures as disclosed for example in Maniatis et al. Molecular cloning. Cold Spring Harbor Press, 1982 and 1989. I suitable digest is made and the fragments are cloned in a vector which is subsequently used to transform an E. coli. Selection is made on the basis of the presence of the lipase gene this can be performed using hybridization if suitable probes are available. Alternatively it is possible to use an expression vector in which case it becomes possible to select for the presence of the desired genes using a suitable assay such as halo formation when lipase is screened for. Furthermore expression can also be monitored using immunological detection of the protein when suitable antibodies are available.
  • lipase modulator gene is necessary for lipase production the chromosomal copy of the gene is sufficient to allow an increase of 2000%. Only at this point introduction of additional modulation gene copies will result in higher lipase production.
  • Lipase and lipase modulator gene sequences were compared using computer analysis.
  • a mole ⁇ cular enzyme screening assay as described in EP 334462. From this work it was concluded that Pseudomonas species belonging to the same RNA homology group as P. pseudoalcaligenes show a rather strong homology, whereas Pseudomonas species belonging to a different RNA homology group (Palleroni, 1973) and other bacterial species show no hybridization at all. A correlation between both methods was well established, which makes it possible to determine homology with uncharacterized lipase genes.
