Deleted entry:  cellobiose dehydrogenase (quinone). Now known to be proteolytic product of EC, cellobiose dehydrogenase (acceptor)
[EC created 1983, deleted 2002]
Accepted name: glucose 1-dehydrogenase (PQQ, quinone)
Reaction: D-glucose + ubiquinone = D-glucono-1,5-lactone + ubiquinol
Other name(s): quinoprotein glucose dehydrogenase; membrane-bound glucose dehydrogenase; mGDH; glucose dehydrogenase (PQQ-dependent); glucose dehydrogenase (pyrroloquinoline-quinone); quinoprotein D-glucose dehydrogenase
Systematic name: D-glucose:ubiquinone oxidoreductase
Comments: Integral membrane protein containing PQQ as a cofactor. It also contains bound ubiquinone and Mg2+ or Ca2+. Electron acceptor is membrane ubiquinone but usually assayed with phenazine methosulfate. Like in all other quinoprotein alcohol dehydrogenases the catalytic domain has an 8-bladed propeller structure. It occurs in a wide range of bacteria. Catalyses a direct oxidation of the pyranose form of D-glucose to the lactone and thence to D-gluconate in the periplasm. Oxidizes other monosaccharides including the pyranose forms of pentoses.

Systematic name: sn-glycerol 3-phosphate:quinone oxidoreductase
Comments: This flavin-dependent dehydrogenase is an essential membrane enzyme, functioning at the central junction of glycolysis, respiration and phospholipid biosynthesis. In bacteria, the enzyme is localized to the cytoplasmic membrane [6], while in eukaryotes it is tightly bound to the outer surface of the inner mitochondrial membrane [2]. In eukaryotes, this enzyme, together with the cytosolic enzyme EC, glycerol-3-phosphate dehydrogenase (NAD+), forms the glycerol-3-phosphate shuttle by which NADH produced in the cytosol, primarily from glycolysis, can be reoxidized to NAD+ by the mitochondrial electron-transport chain [3]. This shuttle plays a critical role in transferring reducing equivalents from cytosolic NADH into the mitochondrial matrix [7,8]. Insect flight muscle uses only CoQ10 as the physiological quinone whereas hamster and rat mitochondria use mainly CoQ9 [4]. The enzyme is activated by calcium [3].

Accepted name: alcohol dehydrogenase (quinone)
Reaction: ethanol + ubiquinone = acetaldehyde + ubiquinol
Other name(s): type III ADH; membrane associated quinohaemoprotein alcohol dehydrogenase
Systematic name: alcohol:quinone oxidoreductase
Comments: Only described in acetic acid bacteria where it is involved in acetic acid production. Associated with membrane. Electron acceptor is membrane ubiquinone. A model structure suggests that, like all other quinoprotein alcohol dehydrogenases, the catalytic subunit has an 8-bladed ‘propeller’ structure, a calcium ion bound to the PQQ in the active site and an unusual disulfide ring structure in close proximity to the PQQ; the catalytic subunit also has a heme c in the C-terminal domain. The enzyme has two additional subunits, one of which contains three molecules of heme c. It does not require amines for activation. It has a restricted substrate specificity, oxidizing a few primary alcohols (C2 to C6), but not methanol, secondary alcohols and some aldehydes. It is assayed with phenazine methosulfate or with ferricyanide.

Other name(s): fructose 5-dehydrogenase (acceptor); D-fructose dehydrogenase; D-fructose:(acceptor) 5-oxidoreductase
Systematic name: D-fructose:ubiquinone 5-oxidoreductase
Comments: The enzyme, characterized from the bacterium Gluconobacter japonicus, is a heterotrimer composed of an FAD-containing large subunit, a small subunit, and a heme c-containing subunit, which is responsible for anchoring the complex to the cytoplasmic membrane and for transferring the electrons to ubiquinone.
