Abstact

Fatty acid synthases are dynamic ensembles of enzymes that can biosynthesize long hydrocarbon chains efficiently. Here we visualize the interaction between the Escherichia coli acyl carrier protein (AcpP) and β-ketoacyl-ACP-synthase I (FabB) using X-ray crystallography, NMR, and molecular dynamics simulations. We leveraged this structural information to alter lipid profiles in vivo and provide a molecular basis for how protein-protein interactions can regulate the fatty acid profile in E. coli.
