In enzymology a ribitol 2-dehydrogenase (EC 1.1.1.56) is an enzyme that catalyzes the chemical reactionribitol + NAD+ D-ribulose + NADH + H+Thus the two substrates of this enzyme are ribitol and NAD+ whereas its 3 products are D-ribulose 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. The systematic name of this enzyme class is ribitol:NAD+ 2-oxidoreductase.
