IUBMB Enzyme Nomenclature


Accepted name: malate dehydrogenase (decarboxylating)

Reaction: (S)-malate + NAD+ = pyruvate + CO2 + NADH

Other name(s): 'malic' enzyme (ambiguous); pyruvic-malic carboxylase (ambiguous); NAD-specific malic enzyme (ambiguous); NAD-malic enzyme (ambiguous); malate dehydrogenase (decarboxylating) (ambiguous)

Systematic name: (S)-malate:NAD+ oxidoreductase (decarboxylating)

Comments: There are several forms of malate dehydrogenases that differ in their use of substrates and cofactors. This particular form is found only in the plant kingdom. Unlike EC, which catalyses a similar reaction, this enzyme can not bind oxaloacetate, and thus does not decarboxylate exogeneously-added oxaloacetate. cf. EC, malate dehydrogenase; EC, malate dehydrogenase (oxaloacetate-decarboxylating); and EC, D-malate dehydrogenase (decarboxylating).
