| + | [https://www.uniprot.org/uniprot/ACCA_STAA8 ACCA_STAA8] Component of the acetyl coenzyme A carboxylase (ACC) complex. First, biotin carboxylase catalyzes the carboxylation of biotin on its carrier protein (BCCP) and then the CO(2) group is transferred by the carboxyltransferase to acetyl-CoA to form malonyl-CoA.[HAMAP-Rule:MF_00823] | ||

| + | The dramatic increase in antibiotic-resistant bacteria has necessitated a search for new antibacterial agents against novel targets. Moiramide B is a natural product, broad-spectrum antibiotic that inhibits the carboxyltransferase component of acetyl-CoA carboxylase, which catalyzes the first committed step in fatty acid synthesis. Herein, we report the 2.6 A resolution crystal structure of moiramide B bound to carboxyltransferase. An unanticipated, but significant finding was that moiramide B bound as the enol/enolate. Crystallographic studies demonstrate that the (4S)-methyl succinimide moiety interacts with the oxyanion holes of the enzyme, supporting the notion that an anionic enolate is the active form of the antibacterial agent. Structure-activity studies demonstrate that the unsaturated fatty acid tail of moiramide B is only needed for entry into the bacterial cell. These results will enable the design of new antibacterial agents against the bacterial form of carboxyltransferase. | ||
