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, 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 prosthetic group into its acetyl thioester [2].
