Systematic name:
2'-(5-triphosphoribosyl)-3'-dephospho-CoA:apo-[citrate (pro-3S)-lyase] 2'-(5-phosphoribosyl)-3'-dephospho-CoA-transferase



The γ-subunit of EC, citrate (pro-3S) lyase, serves as an acyl-carrier protein (ACP) and contains the prosthetic group 2'-(5-triphosphoribosyl)-3'-dephospho-CoA [1,3]. Synthesis and attachment of the prosthetic group requires the concerted action of this enzyme and EC, triphosphoribosyl-dephospho-CoA synthase [1]. In the enzyme from Escherichia coli, the prosthetic group is attached to serine-14 of the ACP via a phosphodiester bond.
