EC Tree
IUBMB 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 [cf. EC 1.1.1.431, D-xylose reductase (NADPH)]. However, a few D-xylose reductases, such as those from Neurospora crassa , Yamadazyma tenuis [2,3], Scheffersomyces stipitis , and the thermophilic fungus Chaetomium thermophilum [4,7], have dual coenzyme specificity, though they still prefer NADPH to NADH. Very rarely the enzyme prefers NADH [cf. EC 1.1.1.430, D-xylose reductase (NADH)].
