EC 1.1.1.405     
Accepted name: ribitol-5-phosphate 2-dehydrogenase (NADP+)
Reaction: D-ribitol 5-phosphate + NADP+ = D-ribulose 5-phosphate + NADPH + H+
Other name(s): acs1 (gene name); bcs1 (gene name); tarJ (gene name); ribulose-5-phosphate reductase; ribulose-5-P reductase; D-ribulose 5-phosphate reductase
Systematic name: D-ribitol-5-phosphate:NADP+ 2-oxidoreductase
Comments: Requires Zn2+. The enzyme, characterized in bacteria, is specific for NADP. It is part of the synthesis pathway of CDP-ribitol. In Haemophilus influenzae it is part of a multifunctional enzyme also catalysing EC 2.7.7.40, D-ribitol-5-phosphate cytidylyltransferase. cf. EC 1.1.1.137, ribitol-5-phosphate 2-dehydrogenase.
