Malate dehydrogenase (oxaloacetate-decarboxylating)

Template:Short description Template:Infobox enzyme In enzymology, a malate dehydrogenase (oxaloacetate-decarboxylating) (Template:EC number) is an enzyme that catalyzes the chemical reaction below

(S)-malate + NAD⁺ $\rightleftharpoons$ 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.
