Reaction: D-ribitol 5-phosphate + NAD(P)+ = D-ribulose 5-phosphate + NAD(P)H + H+
Other name(s): ribitol 5-phosphate dehydrogenase
Systematic name: D-ribitol-5-phosphate:NAD(P)+ 2-oxidoreductase
Comments: The enzyme, characterized from the bacterium Lactobacillus plantarum, can use both NAD+ and NADP+ as electron acceptor [cf. EC 188.8.131.525, ribitol-5-phosphate 2-dehydrogenase (NADP+)].
