NOVEL GLUCOSE DEHYDROGENASE

摘要

The purpose of the present invention is to provide a novel glucose dehydrogenase and a method for producing the same, and applications of the novel glucose dehydrogenase. This flavin-linked glucose dehydrogenase is provided with characteristics (1) to (4) below. (1) Molecular weight: The molecular weight of the polypeptide portion of the enzyme, as measured by SDS-polyacrylamide electrophoresis, is approximately 69 KDa. (2) Km value: The Km value with respect to D-glucose is approximately 10 mM or less. (3) Temperature stability: The glucose dehydrogenase is stable at 50°C or less. (4) pH stability: The glucose dehydrogenase is stable at a pH of 3.0 to 8.0.
