• In enzymology and molecular biology, a holo-[acyl-carrier-protein] synthase (ACPS, EC 2.7.8.7) is an enzyme that catalyzes the chemical reaction: CoA-[4'-phosphopantetheine] + apo-acyl carrier protein ⇌ {\displaystyle \rightleftharpoons } adenosine 3',5'-bisphosphate + holo-acyl carrier protein This enzyme belongs to the family of transferases, specifically those transferring non-standard substituted phosphate groups. (wikipedia.org)
  • This post-translational modification renders holo-ACP capable of acyl group activation via thioesterification of the cysteamine thiol of 4'-PP.
