[Cloning of lysozyme and lysostaphin genes of Staphylococcus aureus and their expression in Bacillus subtilis cells].
The gene of microbial lysozyme (lyz) of S. aureus 118 and the gene of lysostaphin (lzf) of S. aureus RN 3239 were cloned and their expression in B. subtilis cells was shown. Lysozyme production in B. subtilis recombinant clone pLF14-Lyz, obtained as the result of cloning, was 2.5-fold greater than lysozyme production in S. aureus wild strain 118. Lysostaphin production in B. subtilis recombinant strain pLF14-Lzf which had inherited the cloned genes was approximately equal to lysostaphin production observed in S. aureus initial strain RN 3239. The production of lysozyme and lysostaphin in the cells of B. subtilis recombinant strains was observed at 30 degrees C and pH 5.5, while in S. aureus initial strains 118 and RN 3239 bacteria produced lysozyme and lysostaphin at 37 degrees C and pH 7.5 respectively.
