In enzymology a L-gulonate 3-dehydrogenase (EC 1.1.1.45) is an enzyme that catalyzes the chemical reactionL-gulonate + NAD+ 3-dehydro-L-gulonate + NADH + H+Thus the two substrates of this enzyme are L-gulonate and NAD+ whereas its 3 products are 3-dehydro-L-gulonate NADH and H+.This enzyme belongs to the family of oxidoreductases specifically those acting on the CH-OH group of donor with NAD+ or NADP+ as acceptor.
