Protein, dna, cell, and processes for the production of xylitol-dehydrogenase and xylitol

摘要

Proteu00ecna, DNA, cells, and processes for the production of xylitol dehydrogenase and xylitol.Xylitol is produced allowing xylitol dehydrogenase or cells that received the introduction of a DNA codifier of xylitol dehydrogenase.It is a protein according to the following items (a) or (b) below, act (m) on D - glucose.And collecting the xylitol produced: (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 ind in 4 including the substitution:, deletion, insertion, addition or inversion of one or several amino acids, and possesses activity of xylitol dehydrogenase.
