ENZYME entry: EC 1.1.1.430

PURL: https://purl.expasy.org/enzyme/EC/1.1.1.430
Accepted Name
D-xylose reductase (NADH)
Reaction catalysed
xylitol + NAD(+) = D-xylose + NADH + H(+)
Comment(s)
  • Xylose reductases catalyze 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).
  • Some D-xylose reductases have dual cofactor specificity, though they still prefer NADPH to NADH (cf. EC 1.1.1.307).
  • The enzyme from Candida parapsilosis is a rare example of a xylose reductase that significantly prefers NADH, with Km and Vmax values for NADH being 10-fold lower and 10-fold higher, respectively, than for NADPH.
