Malate dehydrogenase (NADP+)

In enzymology, a malate dehydrogenase (NADP+) is an enzyme that catalyzes the chemical reaction


 * (S)-malate + NADP+ $$\rightleftharpoons$$ oxaloacetate + NADPH + H+

Thus, the two substrates of this enzyme are (S)-malate and NADP+, whereas its 3 products are oxaloacetate, 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 (S)-malate:NADP+ oxidoreductase. Other names in common use include NADP+-malic enzyme, NADP+-malate dehydrogenase, malic dehydrogenase (nicotinamide adenine dinucleotide phosphate), malate NADP+ dehydrogenase, NADP+ malate dehydrogenase, NADP+-linked malate dehydrogenase, and malate dehydrogenase (NADP+). This enzyme participates in pyruvate metabolism and carbon fixation. This enzyme has at least one effector, hn.

Structural studies
As of late 2007, two structures have been solved for this class of enzymes, with PDB accession codes and.
