show Brenda entry

EC number

1.1.2.11

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

Comment

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, glucoside 3-dehydrogenase (acceptor).
