In enzymology, glyoxylate reductase (NADP<sup>+</sup>) () is an enzyme that catalyzes the chemical reaction
The two substrates of this enzyme are glycolic acid and oxidised nicotinamide adenine dinucleotide phosphate (NADP<sup>+</sup>). Its products are glyoxylic acid, reduced NADPH, and a proton.
This enzyme belongs to the family of oxidoreductases, specifically those acting on the CH-OH group of donor with NAD<sup>+</sup> or NADP<sup>+</sup> as acceptor. The systematic name of this enzyme class is glycolate:NADP<sup>+</sup> oxidoreductase. Other names in common use include NADPH-glyoxylate reductase, and glyoxylate reductase (NADP<sup>+</sup>). This enzyme participates in pyruvate metabolism and glyoxylate and dicarboxylate metabolism.
As of late 2007, 3 structures have been solved for this class of enzymes, with PDB accession codes , , and .
