In enzymology, quinoprotein glucose dehydrogenase (EC 1.1.5.2) is an enzyme that catalyzes the chemical reaction

  1. REDIRECT Template:Chemical reaction

The two substrates of this enzyme are D-glucose and the cofactor ubiquinone. Its products are glucono-δ-lactone and ubiquinol.[1][2][3][4]

This enzyme belongs to the family of oxidoreductases, specifically those acting on the CH-OH group of donor with a quinone or similar compound as acceptor. The systematic name of this enzyme class is D-glucose:ubiquinone oxidoreductase. Other names in common use include D-glucose:(pyrroloquinoline-quinone) 1-oxidoreductase, glucose dehydrogenase (PQQ-dependent), glucose dehydrogenase (pyrroloquinoline-quinone), and quinoprotein D-glucose dehydrogenase. This enzyme participates in pentose phosphate pathway. It employs one cofactor, PQQ.
