Hexose oxidase

From Wikipedia, the free encyclopedia

In enzymology, a hexose oxidase (EC 1.1.3.5) is an enzyme that catalyzes the chemical reaction

D-glucose + O₂ D-glucono-1,5-lactone + H₂O₂

Thus, the two substrates of this enzyme are D-glucose and O₂, whereas its two products are D-glucono-1,5-lactone and H₂O₂.

This enzyme belongs to the family of oxidoreductases, specifically those acting on the CH-OH group of donor with oxygen as acceptor. The systematic name of this enzyme class is D-hexose:oxygen 1-oxidoreductase. This enzyme participates in pentose phosphate pathway. It employs one cofactor, copper.
