Cocrystal structures of Methanococcus jannaschii diaminopimelate, decarboxylase (DAPDC) bound to a substrate analog, azelaic acid, and its, L-lysine product have been determined at 2.6 A and 2.0 A, respectively., This PLP-dependent enzyme is responsible for the final step of L-lysine, biosynthesis in bacteria and plays a role in beta-lactam antibiotic, resistance in Staphylococcus aureus. Substrate specificity derives from, recognition of the L-chiral center of diaminopimelate and a system of, ionic "molecular rulers" that dictate substrate length. A coupled-enzyme, assay system permitted measurement of kinetic parameters for recombinant, DAPDCs and inhibition constants (K(i)) for azelaic acid (89 microM) and, other substrate analogs. Implications for rational design of, broad-spectrum antimicrobial agents targeted against DAPDCs of, drug-resistant strains of bacterial pathogens, such as Staphylococcus, aureus, are discussed.
