Disclosed are: a novel (S,S)-butanediol dehydrogenase; a gene encoding the enzyme protein; a vector carrying the gene; a transformant having the vector therein; and a method for production of an optically active alcohol using the transformant. The polypeptide has physicochemical properties including a property of reacting, together with NAD+ as a coenzyme, with (2S,3S)-2,3-butanediol to produce (S)-acetoin and a property of reducing, together with NADH as a coenzyme, 2,3-butandione to produce (2S,3S)-2,3-butanediol. |
