IUBMB Enzyme Nomenclature


Accepted name: glucoside 3-dehydrogenase

Reaction: sucrose + acceptor = 3-dehydro-α-D-glucosyl-β-D-fructofuranoside + reduced acceptor

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

Systematic name: D-aldohexoside:acceptor 3-oxidoreductase

Comments: A flavoprotein (FAD). The enzyme acts on D-glucose, D-galactose, D-glucosides and D-galactosides, but D-glucosides react more rapidly than D-galactosides.
