IUBMB Enzyme Nomenclature


Accepted name: glucoside 3-dehydrogenase (cytochrome c)

Reaction: a D-glucoside + a ferric c-type cytochrome = a 3-dehydro-D-glucoside + a ferrous c-type cytochrome

Other name(s): D-glucoside 3-dehydrogenase (ambiguous); D-aldohexopyranoside dehydrogenase (ambiguous); D-aldohexoside:cytochrome c oxidoreductase; hexopyranoside-cytochrome c oxidoreductase

Systematic name: a D-glucoside:ferric c-type cytochrome 3-oxidoreductase

Comments: This bacterial enzyme acts on D-glucose, D-galactose, D-glucosides and D-galactosides, but the best substrates are disaccharides with a glucose moiety at the non-reducing end. It consists of two subunits, a catalytic subunit that contains an FAD cofactor and an iron-sulfur cluster, and a "hitch-hiker" subunit containing a signal peptide for translocation into the periplasm. A dedicated c-type cytochrome protein serves as an electron acceptor, transferring the electrons from the catalytic subunit to the cell's electron transfer chain. cf. EC, glucoside 3-dehydrogenase (acceptor).
