In enzymology, a malate dehydrogenase (oxaloacetate-decarboxylating) (EC 1.1.1.38) is an enzyme that catalyzes the chemical reaction
- (S)-malate + NAD+ pyruvate + CO2 + NADH
Thus, the two substrates of this enzyme are (S)-malate and NAD+, whereas its 3 products are pyruvate, CO2, and NADH.
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:NAD+ oxidoreductase (oxaloacetate-decarboxylating). Other names in common use include malic enzyme, pyruvic-malic carboxylase, NAD+-specific malic enzyme, NAD+-malic enzyme, and NAD+-linked malic enzyme. This enzyme participates in pyruvate metabolism.
Structural studies
As of late 2007, 6 structures have been solved for this class of enzymes, with PDB accession codes 1GZ3, 1LLQ, 1O0S, 1PJL, 1WW8, and 2DVM.
