Comments
  • FUNCTION: Catalyzes the oxidation of various aldopyranoses and disaccharides on carbon-2 to the corresponding 2-keto sugars concomitant with the reduction of O(2) to H(2)O(2). Plays an important role in lignin degradation of wood rot fungi by supplying the essential cosubstrate H(2)O(2) for the ligninolytic peroxidases, lignin peroxidase and manganese-dependent peroxidase. The preferred substrate is D-glucose which is converted to 2-dehydro-D-glucose. Acts also on D-xylose, together with D-glucose the major sugars derived from wood, on L-sorbose, D-galactose and 1,5-anhydroglucitol, a diagnostic marker of diabetes mellitus.
  • CATALYTIC ACTIVITY: D-glucose + O2 = 2-dehydro-D-glucose + H2O2.
  • COFACTOR: Binds 1 FAD covalently per subunit.
  • BIOPHYSICOCHEMICAL PROPERTIES:
    Kinetic parameters:   KM=1.4 mM for D-glucose;
    KM=35.3 mM for 1,5-anhydro-D-glucitol;
    pH dependence:   Optimum pH is about 6.5. Active from pH 5 to 9. Stable from pH 3 to 11;
    Temperature dependence:   Optimum temperature is about 50 degrees Celsius. Active from 30 to 65 degrees Celsius. Thermostable for 30 minutes up to 55 degrees Celsius;
  • SUBUNIT: Homotetramer.
  • SUBCELLULAR LOCATION: Periplasm (By similarity). Note=Hyphal periplasmic space (By similarity).
  • PTM: Not glycosylated.
  • SIMILARITY: Belongs to the GMC oxidoreductase family.
