WebPosttranslational maturation of apo-CP by transfer of the phosphopantetheine arm from CoA-SH to the side chain hydroxyl of a conserved serine residue to yield holo-CP, followed by formation of the thioester bond with a carboxylic acid to generate acyl-S-CPs. In some cases, acyl-S-CP substrates can be substituted by abbreviated NAC thioesters. WebJul 31, 2014 · (1) Movement of the ACP’s phosphopantetheine (Ppant) arm is thought to be coordinated with protein–protein interactions and significant rearrangement of the PKS enzyme assembly. (2-5) The dynamic structures of ACPs and their Ppant arms are difficult to track due to the flexibility of ACPs and ACPs’ transient interactions with catalytic …
