Enzyme Information

1.1.99.28
Glucose-fructose oxidoreductase.
based on mapping to UniProt Q07982
D-glucose + D-fructose = D-gluconolactone + D-glucitol.
-!- D-mannose, D-xylose, D-galactose, 2-deoxy-D-glucose and L-arabinose will function as aldose substrates, but with low affinities. -!- The ketose substrate must be in the open-chain form. -!- The apparent affinity for fructose is low, because little of the fructose substrate is in the open-chain form. -!- Xylulose and glycerone (dihydroxyacetone) will replace fructose, but they are poor substrates. -!- The enzyme from Zymomonas mobilis contains tightly bound NADP(+).
