xylulose reductase

(redirected from xylitol dehydrogenase)

xy·lu·lose re·duc·tase

an enzyme that reversibly converts xylulose to xylitol using either NADH (d-xylulose reductase) or NADPH (l-xylulose reductase); a deficiency of the l form is seen in patients with essential pentosuria.

One is XR-XDH pathway, which contains D-xylose reductase (XR) and xylitol dehydrogenase (XDH), and converts D-xylose to xylulose in S.
Furthermore, the D-xylose reductase (XR), xylitol dehydrogenase (XDH), and xylulokinase (XK) of XR-XDH pathway in the plasmid pYMIK-xy127 [32] were then integrated into the chromosome of BSW4XA1 to obtain BSW4XA2 and [[mu].sub.max] on Dxylose was further increased up to 0.047 [h.sup.-1] (Figure 2(b)).
