EC 1.1.1.431     
Accepted name: D-xylose reductase (NADPH)
Reaction: xylitol + NADP+ = D-xylose + NADPH + H+
Other name(s): XYL1 (gene name, ambiguous); xyl1 (gene name, ambiguous); xyrA (gene name); xyrB (gene name)
Systematic name: xylitol:NADP+ oxidoreductase
Comments: Xylose reductases catalyse the reduction of xylose to xylitol, the initial reaction in the fungal D-xylose degradation pathway. Most of the enzymes exhibit a strict requirement for NADPH (e.g. the enzymes from Saccharomyces cerevisiae, Aspergillus niger, Trichoderma reesei, Candida tropicalis, Saitozyma flava, and Candida intermedia). Some D-xylose reductases have dual coenzyme specificity, though they still prefer NADPH to NADH (cf. EC 1.1.1.307, D-xylose reductase [NAD(P)H]). Very rarely the enzyme prefers NADH (cf. EC 1.1.1.430, D-xylose reductase (NADH)).
