xylose reductase, using either NADH or NADPH, reduces D-xylose to xylitol, subsequently xylitol is oxidized to D-xylulose by a NAD+-linked xylulose dehydrogenase, EC 1.1.1.9

expression of Texr is inducible by the same carbon sources responsible for the induction of genes encoding enzymes relevant to lignocellulose hydrolysis, suggesting a coordinated expression of intracellular and extracellular enzymes relevant to hydrolysis and metabolism of pentose sugars in Talaromyces emersonii in adaptation to its natural habitat. This indicates a potential advantage in survival and response to a nutrient-poor environment

whereas in most bacteria metabolism of D-xylose proceeds via direct isomerization to D-xylulose, catalysed by xylose isomerase (EC 5.3.1.5), in yeasts this conversion is catalysed by the sequential action of two oxidoreductases: xylose reductase and xylitol dehydrogenase (EC 1.1.1.9)
