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

D-ribitol 5-phosphate
 
 
 
H+
 
H+
 
D-ribulose-5-phosphate
 

The two substrates of this enzyme are D-ribitol 5-phosphate and reduced nicotinamide adenine dinucleotide (NAD+). Its products are D-ribulose 5-phosphate, reduced NADH, and a proton. The enzyme can also use the alternative cofactor, nicotinamide adenine dinucleotide phosphate.[1][2]

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.
