Malic enzymes catalyze the oxidative decarboxylation of L-malate to pyruvate and CO(2) with the reduction of the NAD(P)(+) cofactor in the presence of divalent cations. We report the crystal structures at up to 2.1 A resolution of human mitochondrial NAD(P)(+)-dependent malic enzyme in different pentary complexes with the natural substrate malate or pyruvate, the dinucleotide cofactor NAD(+) or NADH, the divalent cation Mn(2+), and the allosteric activator fumarate ...
