FunFam 5868: Soluble aldose sugar dehydrogenase yliI

There are 1 EC terms in this cluster

Please note: EC annotations are assigned to the full protein sequence rather than individual protein domains. Since a given protein can contain multiple domains, it is possible that some of the annotations below come from additional domains that occur in the same protein, but have been classified elsewhere in CATH.

Note: The search results have been sorted with the annotations that are found most frequently at the top of the list. The results can be filtered by typing text into the search box at the top of the table.

EC Term Annotations Evidence
Quinoprotein glucose dehydrogenase (PQQ, quinone). [EC: 1.1.5.2]
D-glucose + ubiquinone = D-glucono-1,5-lactone + ubiquinol.
  • Integral membrane protein containing PQQ as prosthetic group.
  • It also contains bound ubiquinone and Mg(2+) or Ca(2+).
  • 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.
  • Catalyzes 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.
  • Formerly EC 1.1.99.17.
