Functioni

Catalyzes the NAD(P)+-dependent oxidation of D-glucose to D-gluconate via gluconolactone. To a lesser extent, is also active with xylose as substrate, but mannose, arabinose, galactose, fructose 6-phosphate, glucose 6-phosphate, glycerinaldehyde 3-phosphate, ribose, sorbitol, ethanol, erythritol, or lactose are not oxidized by the enzyme. Can utilize both NAD+ and NADP+ as electron acceptor, with a marked preference for NADP+. Is involved in the degradation of glucose through a non-phosphorylative variant of the Entner-Doudoroff pathway.1 Publication

Catalytic activityi

D-glucose + NAD(P)+ = D-glucono-1,5-lactone + NAD(P)H.1 Publication

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
