Fatty acids are key building blocks for the phospholipid components of cell membranes and are determinants of intracellular communication, in the form of lipid second messengers [Prieschl00], and fatty acyl moieties of proteins that modify their location and function [Resh99].
The initial steps in fatty acid biosynthesis catalyze the production of the first major intermediate, acetoacetyl-ACP, from the precursor acetyl-CoA. There are several alternate ways to generate this intermediate from acetyl-CoA, which involve some combination of the intermediates malonyl-CoA, a malonyl-[acp], and acetyl-ACP. These early reactions in the biosynthesis of fatty acids can use either holo-[acyl-carrier protein] (ACP) or coenzyme A to activate intermediates. The pathway illustrated here depicts the use of holo-[acyl-carrier protein] compounds for this purpose.
