3-dehydro-D-guloside 4-epimerase

UniProtKB accession:  P76044

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Catalyzes the epimerization at C4 of 3-dehydro-D-gulosides leading to 3-dehydro-D-glucosides. Probably functions in a metabolic pathway that transforms D-gulosides to D-glucosides. Can use methyl alpha-3-dehydro-D-glucoside and methyl beta-3-dehydro-D-glucoside as substrates in vitro. However, the actual specific physiological substrates for this metabolic pathway are unknown. Cannot act on D-psicose, D-fructose, D-tagatose, D-sorbose, L-xylulose, or L-ribulose.
