HYDROGEN PEROXIDE DEGRADING ENZYME

摘要

PROBLEM TO BE SOLVED: To provide a novel hydrogen peroxide degrading enzyme derived from Lactobacillus.

SOLUTION: Disclosed is a Lactobacillus-derived hydrogen peroxide degrading enzyme having the following physicochemical characteristics: (1) substrate specificity: showing high reactivity with hydrogen peroxide in the presence of NAD(P)H and not substantially acting on peroxide; and (2) molecular weight: about 50 kDa (measured by SDS polyacrylamide gel electrophoresis). Pediococcus pentosaceus TY1573 strain (NITE P-91) is suitable as the lactobacillus.
