EC 1.1.1.40     
Accepted name: malate dehydrogenase (oxaloacetate-decarboxylating) (NADP+)
Reaction: (1) (S)-malate + NADP+ = pyruvate + CO2 + NADPH
(2) oxaloacetate = pyruvate + CO2
Other name(s): ’malic’ enzyme (ambiguous); pyruvic-malic carboxylase (ambiguous); malate dehydrogenase (decarboxylating, NADP+); NADP+-linked decarboxylating malic enzyme; NADP+-malic enzyme; NADP+-specific malic enzyme; NADP+-specific malate dehydrogenase; malate dehydrogenase (NADP+, decarboxylating); L-malate:NADP+ oxidoreductase
Systematic name: (S)-malate:NADP+ oxidoreductase (oxaloacetate-decarboxylating)
Comments: The enzyme catalyses the oxidative decarboxylation of (S)-malate in the presence of NADP+ and divalent metal ions, and the decarboxylation of oxaloacetate. cf. EC 1.1.1.38, malate dehydrogenase (oxaloacetate-decarboxylating), and EC 1.1.1.39, malate dehydrogenase (decarboxylating).
