ENZYME entry: EC 1.1.2.11

Accepted Name
glucoside 3-dehydrogenase (cytochrome c).
Alternative Name(s)
D-aldohexopyranoside dehydrogenase.
D-glucoside 3-dehydrogenase.
hexopyranoside-cytochrome c oxidoreductase.
Reaction catalysed
a D-glucoside + 2 Fe(III)-[cytochrome c] <=> a 3-dehydro-D-glucoside + 2 Fe(II)-[cytochrome c] + 2 H(+)
Comment(s)
  • 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 1.1.99.13.
