Ribitol 5 phosphate 2 dehydrogenase

In enzymology, a ribitol-5-phosphate 2-dehydrogenase (EC 1.1.1.137) is an enzyme that catalyzes the chemical reaction

The 3 substrates of this enzyme are D-ribitol 5-phosphate, NAD⁺, and NADP⁺, whereas its 4 products are D-ribulose 5-phosphate, NADH, NADPH, 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 D-ribitol-5-phosphate:NAD(P)⁺ 2-oxidoreductase. This enzyme is also called dehydrogenase, ribitol 5-phosphate. This enzyme participates in pentose and glucuronate interconversions.
