Patent ID: 8129163

Claim:
A purified DNA which is any one of the following DNAs (A), (B), (C), and (D): (A) a DNA comprising the nucleotide sequence shown under SEQ ID NO:2 in the sequence listing; (B) a DNA hybridizable under a stringent condition with a DNA that comprises the nucleotide sequence complementary to the nucleotide sequence shown under SEQ ID NO:2 in the sequence listing, and coding for a polypeptide that has activity to react with acetophenone to reduce into (S)-1-phenylethanol, wherein said DNA hybridizable under a stringent condition is obtainable by hybridization with a filter in the presence of 0.7 to 1.0 M NaCl, at 65° C., followed by washing the filter with a 0.2-fold concentration of SSC solution at 65° C.; (C) a DNA having sequence identity of 90% or higher to the nucleotide sequence shown under SEQ ID NO:2 in the sequence listing, and coding for a polypeptide that has activity to react with acetophenone to reduce into (S)-1-phenylethanol; and (D) a DNA comprising a nucleotide sequence that results from deletion, insertion, substitution and/or addition of 100 or less nucleotides in the nucleotide sequence shown under SEQ ID NO:2 in the sequence listing, and coding for a polypeptide that has activity to react with acetophenone to reduce into (S)-1-phenylethanol.
