The present invention has its object to provide a novel (S,S)-butanediol dehydrogenase. The present invention also has its object to provide a gene coding for the enzyme protein, a vector containing the gene, a transformant harboring the vector, and a method of producing an optically active alcohol using the transformant. The polypeptide according to one embodiment of the present invention has the physicochemical properties including actions such as: acting on (2S, 3S) -2, 3-butanediol to form (S) -acetoin in the presence of NAD + as a coenzyme; and reducing 2,3-butanedione to form (2S, 3S) -2, 3-butanediol in the presence of NADH as a coenzyme. |
