In enzymology, a glucose-fructose oxidoreductase (EC 1.1.99.28) is an enzyme that catalyzes the chemical reaction
- D-glucose + D-fructose D-gluconolactone + D-glucitol
Thus, the two substrates of this enzyme are D-glucose and D-fructose, whereas its two products are D-gluconolactone and D-glucitol.
This enzyme belongs to the family of oxidoreductases, specifically those acting on the CH-OH group of donor with other acceptors. The systematic name of this enzyme class is D-glucose:D-fructose oxidoreductase.
Structural studies
As of late 2007, 7 structures have been solved for this class of enzymes, with PDB accession codes 1H6A, 1H6B, 1H6C, 1H6D, 1OFG, 1RYD, and 1RYE.
