Abstract

Phosphopantetheine (or pantetheine 4' phosphate) is the prosthetic group of acyl carrier proteins (ACP) in some multienzyme complexes where it serves as a 'swinging arm' for the attachment of activated fatty acid and amino-acid groups [1].

The amino-terminal region of the ACP proteins is well defined and consists of alpha four helices arranged in a right-handed bundle held together by interhelical hydrophobic interactions. The Asp-Ser-Leu (DSL) motif is conserved in all of the ACP sequences, and the 4'-PP prosthetic group is covalently linked via a phosphodiester bond to the serine residue. The DSL sequence is present at the amino terminus of helix II, a domain of the protein referred to as the recognition helix and which is responsible for the interaction of ACPs with the enzymes of type II fatty acid synthesis [2].
