Glucose dehydrogenase (EC 1.1.1.47) is an oxidoreductase that can be obtained from various microorganisms and tissues. It is a white amorphous powder, α- Galactosidase catalysis α- The hydrolysis of galactoside bonds can remove anti nutritional factors from feed and soy based foods α- Transforming and decomposing galactosides to improve their nutritional composition. In addition, this enzyme has certain applications in the pharmaceutical, thickener treatment, and papermaking industries. Mechanism of action Glucose dehydrogenase specifically oxidizes and decomposes glucose molecules to produce gluconic acid through the pentose phosphate pathway, accompanied by the production of hydrogen negative ions. The action of this enzyme also requires the participation of oxidized coenzyme NAD+or NADP+, and the electron acceptor NAD+or NADP+quickly binds to the generated hydrogen negative ions to generate reduced coenzyme NADH or NADPH, forming a cofactor regeneration cycle.
