ENZYME entry: EC

Accepted Name
soluble quinoprotein glucose dehydrogenase.
Alternative Name(s)
glucose dehydrogenase (PQQ-dependent).
soluble glucose dehydrogenase.
Reaction catalysed
A + D-glucose <=> AH2 + D-glucono-1,5-lactone
  • Soluble periplasmic enzyme containing PQQ as prosthetic group, bound to a calcium ion.
  • Electron acceptor is not known.
  • It is assayed with Wurster's Blue or phenazine methosulfate.
  • It has negligible sequence or structure similarity to other quinoproteins.
  • It catalyzes an exceptionally high rate of oxidation of a wide range of aldose sugars, including D-glucose, galactose, arabinose and xylose, and also the disaccharides lactose, cellobiose and maltose.
  • It has been described only in Acinetobacter calcoaceticus.
