Other name(s): HS-acyl-carrier protein:acetate ligase; [acyl-carrier protein]:acetate ligase; MadH; ACP-SH:acetate ligase
Systematic name: acetate:[acyl-carrier-protein] ligase (AMP-forming)
Comments: This enzyme, from the anaerobic bacterium Malonomonas rubra, is a component of the multienzyme complex EC 7.2.4.4, biotin-dependent malonate decarboxylase. The enzyme uses the energy from hydrolysis of ATP to convert the thiol group of the acyl-carrier-protein-bound 2'-(5-phosphoribosyl)-3'-dephospho-CoA cofactor into its acetyl thioester [2].
