POLYPEPTIDE HAVING D-LACTATE DEHYDROGENASE ACTIVITY, POLYNUCLEOTIDE ENCODING THE POLYPEPTIDE, AND PROCESS FOR PRODUCTION OF D-LACTIC ACID |
摘要 |
Highly productive D-lactic acid fermentation is achieved by using a transformant obtained by introducing into a host cell a polynucleotide encoding a polypeptide according to any one of the following (A) to (C) in such a manner that the polypeptide is expressed, which polypeptide has a D-Iactate dehydrogenase activity higher than those of conventional polypeptides: (A) a polypeptide having the amino acid sequence shown in SEQ ID NO:1 or 2; (B) a polypeptide having the same amino acid sequence as shown in SEQ ID NO:1 or 2 except that one or several amino acids are substituted, deleted, inserted and/or added, which polypeptide has a D-lactate dehydrogenase activity; and (C) a polypeptide having an amino acid sequence which has a sequence identity of not less than 80% to the amino acid sequence shown in SEQ ID NO:1 or 2, which polypeptide has a D-lactate dehydrogenase activity. |
