Ribitol 2-dehydrogenase

In enzymology, a ribitol 2-dehydrogenase is an enzyme that catalyzes the chemical reaction
The two substrates of this enzyme are ribitol and oxidised nicotinamide adenine dinucleotide. Its products are D-ribulose, reduced NADH, and a proton.
This enzyme participates in pentose and glucuronate interconversions.

Nomenclature

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. Other names in common use include adonitol dehydrogenase, ribitol dehydrogenase A, ribitol dehydrogenase B, and ribitol dehydrogenase D.
