Structural highlights
FunctionFABF_ECOLI Catalyzes the condensation reaction of fatty acid synthesis by the addition to an acyl acceptor of two carbons from malonyl-ACP. Has a preference for short chain acid substrates and may function to supply the octanoic substrates for lipoic acid biosynthesis. Evolutionary Conservation Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf. Publication Abstract from PubMedIn the biosynthesis of fatty acids, the beta-ketoacyl-acyl carrier protein (ACP) synthases catalyze chain elongation by the addition of two-carbon units derived from malonyl-ACP to an acyl group bound to either ACP or CoA. The enzyme is a possible drug target for treatment of certain cancers and for tuberculosis. The crystal structure of the complex of the enzyme from Escherichia coli, and the fungal mycotoxin cerulenin reveals that the inhibitor is bound in a hydrophobic pocket formed at the dimer interface. Cerulenin is covalently attached to the active site cysteine through its C2 carbon atom. The fit of the inhibitor to the active site is not optimal, and there is thus room for improvement through structure based design.
