The enzyme [acyl-carrier-protein] phosphodiesterase (EC 3.1.4.14) catalyzes the reaction
This enzyme belongs to the family of hydrolases, specifically those acting on phosphoric diester bonds. The systematic name is holo-[acyl-carrier-protein] 4′-pantetheine-phosphohydrolase. Other names in common use include ACP hydrolyase, ACP phosphodiesterase, AcpH, and [acyl-carrier-protein] 4′-pantetheine-phosphohydrolase. This enzyme participates in pantothenate and CoA biosynthesis.
As of late 2007, two structures have been solved for this class of enzymes, with PDB accession codes 1T5B and 1TIK.
The acyl carrier protein (ACP) is a cofactor of both fatty acid and polyketide biosynthesis machinery. It is one of the most abundant proteins in cells of E. coli. In both cases, the growing chain is bound to the ACP via a thioester derived from the distal thiol of a 4'-phosphopantetheine moiety.
Pantetheine is the cysteamine amide analog of pantothenic acid (vitamin B5). The dimer of this compound, pantethine is more commonly known, and is considered to be the most potent form of vitamin B5. Pantetheine is an intermediate in the production of coenzyme A by the body.
Phosphopantetheine, also known as 4'-phosphopantetheine, is a prosthetic group of several acyl carrier proteins including the acyl carrier proteins (ACP) of fatty acid synthases, ACPs of polyketide synthases, the peptidyl carrier proteins (PCP), as well as aryl carrier proteins (ArCP) of nonribosomal peptide synthetases (NRPS). It is also present in formyltetrahydrofolate dehydrogenase.

Fatty-acyl-CoA Synthase, or more commonly known as yeast fatty acid synthase, is an enzyme complex responsible for fatty acid biosynthesis, and is of Type I Fatty Acid Synthesis (FAS). Yeast fatty acid synthase plays a pivotal role in fatty acid synthesis. It is a 2.6 MDa barrel shaped complex and is composed of two, unique multi-functional subunits: alpha and beta. Together, the alpha and beta units are arranged in an α6β6 structure. The catalytic activities of this enzyme complex involves a coordination system of enzymatic reactions between the alpha and beta subunits. The enzyme complex therefore consists of six functional centers for fatty acid synthesis.
