L-gulonate 3-dehydrogenase
In enzymology, a L-gulonate 3-dehydrogenase is an enzyme that catalyzes the chemical reaction
The two substrates of this enzyme are L-gulonic acid and oxidised nicotinamide adenine dinucleotide. Its products are 3-dehydro-L-gulonic acid, reduced NADH, and a proton.
This enzyme belongs to the family of oxidoreductases, specifically those acting on the CH-OH group of donor with NAD+ or NADP+ as acceptor. The systematic name of this enzyme class is L-gulonate:NAD+ 3-oxidoreductase. Other names in common use include L-3-aldonate dehydrogenase, L-3-aldonic dehydrogenase, L-gulonic acid dehydrogenase, L-beta-hydroxyacid dehydrogenase, L-beta-hydroxy-acid-NAD+-oxidoreductase, and L-3-hydroxyacid dehydrogenase. This enzyme participates in pentose and glucuronate interconversions.
