Abstract
Xylitol is produced by allowing xylitol dehydrogenase or cells instoduced with a DNA coding for xylitol dehydrogenase, which is a protein of the following (A) or (B) to act on D-xylulose, and collecting produced xylitol: (A) a protein which has the amino acid sequence of SEQ ID NO: 4; (B) a protein which has the amino acid sequence of SEQ ID NO: 4 including substitution, deletion, insertion, addition, or inversion of one or several amino acids, and has xylitol dehydrogenase activity.
