| CAS Registry Number | 81669-60-5 |
| Comments | Integral membrane protein containing PQQ as prosthetic group. 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. |
| Cofactor | Ca2+ or Mg2+;pyrroloquinoline quinone |
| History | |
| Reactions | D-glucose + ubiquinone = D-glucono-1,5-lactone + ubiquinol. |
