CC -!- FUNCTION: Catalyzes the initial reaction in the xylose utilization
CC pathway by reducing D-xylose into xylitol. Xylose is a major component
CC of hemicelluloses such as xylan. Most fungi utilize D-xylose via three
CC enzymatic reactions, xylose reductase (XR), xylitol dehydrogenase
CC (XDH), and xylulokinase, to form xylulose 5-phosphate, which enters
CC pentose phosphate pathway (By similarity). {ECO:0000250}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=NAD(+) + xylitol = D-xylose + H(+) + NADH;
CC Xref=Rhea:RHEA:27441, ChEBI:CHEBI:15378, ChEBI:CHEBI:17151,
CC ChEBI:CHEBI:53455, ChEBI:CHEBI:57540, ChEBI:CHEBI:57945;
CC EC=1.1.1.307;
CC -!- CATALYTIC ACTIVITY:
CC Reaction=NADP(+) + xylitol = D-xylose + H(+) + NADPH;
CC Xref=Rhea:RHEA:27445, ChEBI:CHEBI:15378, ChEBI:CHEBI:17151,
CC ChEBI:CHEBI:53455, ChEBI:CHEBI:57783, ChEBI:CHEBI:58349;
CC EC=1.1.1.307;
CC -!- PATHWAY: Carbohydrate metabolism; D-xylose degradation.
CC -!- SIMILARITY: Belongs to the aldo/keto reductase family. {ECO:0000305}.
