Simplified mechanism of the reaction catalyzed by Beta-ketoacyl-ACP-synthase. The ACP-bound acyl chain (left, blue) is extended by two carbon atoms (green) stemming from malonyl-ACP. Red arrows indicate net electron flow (back-and-forth flow of electrons not shown). The newly generated bond is highlighted in red.
