EC Number 2.7.8.7
CAS编号 37278-30-1
Comments Requires Mg2+. All polyketide synthases, fatty-acid synthases and non-ribosomal peptide synthases require post-translational modification of their constituent acyl-carrier-protein (ACP) domains to become catalytically active. The inactive apo-proteins are converted into their active holo-forms by transfer of the 4′-phosphopantetheinyl moiety of CoA to the sidechain hydroxy group of a conserved serine residue in each ACP domain [3]. The enzyme from human can activate both the ACP domain of the human cytosolic multifunctional fatty acid synthase system (EC?2.3.1.85) and that associated with human mitochondria as well as peptidyl-carrier and acyl-carrier-proteins from prokaryotes [6]. Removal of the 4-phosphopantetheinyl moiety from holo-ACP is carried out by EC?3.1.4.14, [acyl-carrier-protein] phosphodiesterase.
Cofactor Mg2+
History
Reactions CoA-(4′-phosphopantetheine) + apo-[acyl-carrier-protein] = adenosine 3′,5′-bisphosphate + holo-[acyl-carrier-protein].
