xylitol:NADP+ oxidoreductase
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)).
