Reaction: (1) (S)-malate + NAD+ = pyruvate + CO2 + NADH
(2) oxaloacetate = pyruvate + CO2
Other name(s): 'malic' enzyme (ambiguous); pyruvic-malic carboxylase (ambiguous); NAD-specific malic enzyme; NAD-malic enzyme; NAD-linked malic enzyme
Systematic name: (S)-malate:NAD+ oxidoreductase (oxaloacetate-decarboxylating)
Comments: Unlike EC 1.1.1.39, malate dehydrogenase (decarboxylating), this enzyme can also decarboxylate oxaloacetate. cf. EC 1.1.1.40, malate dehydrogenase (oxaloacetate-decarboxylating) (NADP+).
