Enzyme Commission Summary:
The γ-subunit of EC 220.127.116.11, citrate (pro-3S)-lyase, serves as an acyl-carrier protein (ACP) and contains the prosthetic group 2'-(5''-triphospho-α-D-ribosyl)-3'-dephospho-CoA [Schneider00a, Schneider02]. Synthesis and attachment of the prosthetic group requires the concerted action of this enzyme and EC 18.104.22.168, triphosphoribosyl-dephospho-CoA synthase [Schneider00a]. In the enzyme from E. coli, the prosthetic group is attached to serine-14 of the ACP via a phosphodiester bond.
