MetaCyc Reaction: 1.1.99.28

Superclasses: Reactions Classified By Conversion Type Simple Reactions Chemical Reactions
Reactions Classified By Substrate Small-Molecule Reactions

EC Number: 1.1.99.28

Enzymes and Genes:
glucose-fructose oxidoreductase Inferred from experiment : gfo ( Zymomonas mobilis )

In Pathway: sorbitol biosynthesis II

The reaction direction shown, that is, A + B ↔ C + D versus C + D ↔ A + B, is in accordance with the Enzyme Commission system.

Mass balance status: Balanced.

Enzyme Commission Primary Name: glucose-fructose oxidoreductase

Standard Gibbs Free Energy (ΔrG in kcal/mol): -5.630005 Inferred by computational analysis [Latendresse13]

Enzyme Commission Summary:
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+.
