malic enzyme
malic enzyme[′mal·ik ′en‚zīm] (biochemistry) An enzyme which utilizes nicotinamide-adenine dinucleotide phosphate (NADP) to catalyze the oxidative decarboxylation of malic acid to pyruvic acid and carbon dioxide. Also known as malate dehydrogenase. malic enzyme
ma·late de·hy·dro·gen·ase (MD), an enzyme that, using either NAD+ or NADP+, catalyzes the dehydrogenation of malate to oxaloacetate or its decarboxylation to pyruvate and CO2. At least six malate dehydrogenases are known, distinguished by their products, use of NAD+ or NADP+, and specificity of substrate (one acts on d-malate, the rest act on l-malate); one of these proteins is an enzyme in the tricarboxylic acid cycle. Synonym(s): malic acid dehydrogenase, malic dehydrogenase, malic enzyme, pyruvic-malic carboxylasemalic enzyme (1) Malate dehydrogenase (oxaloacetate-decarboxylating), EC 1.1.1.38.
(2) Malate dehydrogenase (decarboxylating), EC 1.1.1.39.
(3) Malate dehydrogenase (oxaloacetate-decarboxylating) (NADP+), EC 1.1.1.40. |
