In enzymology, a glucose 1-dehydrogenase (FAD, quinone) (EC 1.1.5.9) is an enzyme that catalyzes the chemical reaction Thus, the two substrates of this enzyme are D-glucose and a quinone, whereas its two products are D-glucono-1,5-lactone and a quinol.
This enzyme belongs to the family of oxidoreductases, specifically those acting on the CH-OH group of donor with other acceptors.
The systematic name of this enzyme class is D-glucose:acceptor 1-oxidoreductase.
Other names in common use include glucose dehydrogenase (Aspergillus), glucose dehydrogenase (decarboxylating), and D-glucose:(acceptor) 1-oxidoreductase.
This enzyme participates in pentose phosphate pathway.
