Abstract: Structural studies of the human mitochondrial NAD(Pt-dependent malic enzyme (m-NAD-ME) establish that malic enzymes belong to a new class of oxidative decarboxylases: An open and a closed form of the enzyme have been observed from the crystallographic analysis, with the closed form also revealing the binding modes of the divalent cation and the transition-state analog inhibitor oxalate. The structures show that E255, D256 and D279 are the ligands of the cation, and suggest that Y112 and K183 may be the catalytic residues of the enzyme.
