Thus, the two substrates of this enzyme are D-xylose and NADP⁺, whereas its 3 products are D-xylono-1,5-lactone, NADPH, and H⁺.

This enzyme belongs to the family of oxidoreductases, specifically those acting on the CH-OH group of donor with NAD⁺ or NADP⁺ as acceptor. The systematic name of this enzyme class is D-xylose:NADP⁺ 1-oxidoreductase. Other names in common use include D-xylose (nicotinamide adenine dinucleotide phosphate), dehydrogenase, D-xylose-NADP⁺ dehydrogenase, D-xylose:NADP⁺ oxidoreductase, and D-xylose 1-dehydrogenase (NADP⁺).
