Abstract
The present invention has its object to provide a method of producing an erythro- or threo-2-amino-3-hydroxypropionic acid ester, and so forth. The present invention relates to: a method of asymmetrically reducing an N-2-amino-3-oxopropionic acid ester by allowing cells of a microorganism to act thereon; a polypeptide having an activity of asymmetrically reducing a carbonyl compound to give an optically active alcohol, which is isolated from a microorganism belonging to genus; a DNA coding for the polypeptide; and a transformant producing the polypeptide. The invention also relates to a method of producing an optically active alcohol by reducing a carbonyl compound with the help of the polypeptide or the transformant.
