摘要

PROBLEM TO BE SOLVED: To catalyze the epimerization of various sugars having a small amount of by-products, low substrate specificity, and / or excellent heat resistance and suitable for use on an industrial scale. To provide the enzyme to be used. SOLUTION: An enzyme agent for an epimerization catalyst of a sugar containing any one of the following proteins (a) to (c) is provided. (a) A protein consisting of the amino acid sequence shown in SEQ ID NO: 2; (b) A protein consisting of an amino acid sequence having 90% or more amino acid sequence identity with respect to the amino acid sequence shown in SEQ ID NO: 2 and having sugar epimerization activity; (c) A protein having an amino acid sequence in which one or several amino acids are substituted, inserted, deleted and / or added in the amino acid sequence shown in SEQ ID NO: 2 and having sugar epimerization activity.
