摘要:
A novel D-amidase is described. The enzyme specifically hydrolyzes D-α-alanineamide into D-α-alanine. It is produced by culturing a microorganism belonging to the genus Arthrobacter , and is useful as an enzyme for efficiently producing D-α-alanine having a high optical purity and/or L-α-alanineamide from DL-α-alanineamide or D-α-alanineamide at low cost.
