ID 1.1.99.35 DE soluble quinoprotein glucose dehydrogenase. AN glucose dehydrogenase (PQQ-dependent). AN soluble glucose dehydrogenase. CA A + D-glucose = AH2 + D-glucono-1,5-lactone. CC -!- Soluble periplasmic enzyme containing PQQ as cofator, bound to a CC calcium ion. CC -!- Electron acceptor is not known. CC -!- It is assayed with Wurster's Blue or phenazine methosulfate. CC -!- It has negligible sequence or structure similarity to other CC quinoproteins. CC -!- It catalyzes an exceptionally high rate of oxidation of a wide range CC of aldose sugars, including D-glucose, galactose, arabinose and CC xylose, and also the disaccharides lactose, cellobiose and maltose. CC -!- It has been described only in Acinetobacter calcoaceticus. DR P05465, DHGA_ACICA ; //
