Abstract: PURPOSE: Provided are a gene coding lipase of Acinetobacter species SY-01 with stereoselective substrate specificity and a protein expressed therefrom. CONSTITUTION: A gene is characterized by coding amino acid sequence of lipase of Acinetobacter species SY-01, represented by the SEQ ID NO:2. A transformed Bacillus subtilis 168/pSYLipSM(1) (KCTC 10267BP) is obtained by transformation with a recombinant vector plasmid pSYLipSM(1) containing the gene coding the lipase of Acinetobacter species SY-01. The lipase of Acinetobacter species SY-01 is manufactured by the steps of culturing the transformed bacillus subtilis, and isolating and purifying expressed lipase of Acinetobacter species SY-01 from the cultured cell.

Abstract: PURPOSE: Provided are a gene encoding mutant lipase of acinetobacter species SY-01, Bacillus subtilis 168/pSYLipM58 (KCTC 10422BP) as a transformant containing the same, and mutant lipase expressed therefrom displaying improved enzyme activity. The transformant is useful as a bio-catalyst. CONSTITUTION: The gene encoding mutant lipase of Acinetobacter species SY-01 has the nucleotide sequence set forth in SEQ ID NO:2. A recombinant vector of Acinetobacter species SY-01, plasmid pSYLipM58, comprises the gene encoding mutant lipase of Acinetobacter species SY-01. The transformant, Bacillus subtilis 168/pSYLipM58(KCTC 10422BP), contains the plasmid pSYLipM58. The method for producing the mutant lipase of Acinetobacter species SY-01 comprises the steps of: culturing Bacillus subtilis 168/pSYLipM58(KCTC 10422BP); and recovering and purifying the mutant lipase of Acinetobacter species SY-01 expressed from the cultured microorganism.
