ID 1.1.5.2 DE quinoprotein glucose dehydrogenase (PQQ, quinone). AN D-glucose:(pyrroloquinoline-quinone) 1-oxidoreductase. AN glucose dehydrogenase (PQQ-dependent). AN glucose dehydrogenase (pyrroloquinoline-quinone). AN quinoprotein D-glucose dehydrogenase. CA a ubiquinone + D-glucose = a ubiquinol + D-glucono-1,5-lactone. CC -!- Integral membrane protein containing PQQ as cofactor. CC -!- It also contains bound ubiquinone and Mg(2+) or Ca(2+). CC -!- Electron acceptor is membrane ubiquinone but usually assayed with CC phenazine methosulfate. CC -!- Like in all other quinoprotein alcohol dehydrogenases the catalytic CC domain has an 8-bladed 'propeller' structure. CC -!- It occurs in a wide range of bacteria. CC -!- Catalyzes a direct oxidation of the pyranose form of D-glucose to the CC lactone and thence to D-gluconate in the periplasm. CC -!- Oxidizes other monosaccharides including the pyranose forms of CC pentoses. CC -!- Formerly EC 1.1.99.17. DR P13650, DHGB_ACICA ; P15877, DHG_ECOLI ; P27175, DHG_GLUOX ; //
