Accepted name: malonyl-S-ACP:biotin-protein carboxyltransferase
Reaction: a malonyl-[acyl-carrier protein] + a biotinyl-[protein] = an acetyl-[acyl-carrier protein] + a carboxybiotinyl-[protein]

Other name(s): malonyl-S-acyl-carrier protein:biotin-protein carboxyltransferase; MadC/MadD; MadC,D; malonyl-[acyl-carrier protein]:biotinyl-[protein] carboxyltransferase
Systematic name: malonyl-[acyl-carrier protein]:biotinyl-[protein] carboxytransferase
Comments: Derived from the components MadC and MadD of the anaerobic bacterium Malonomonas rubra, this enzyme is a component of EC, biotin-dependent malonate decarboxylase. The carboxy group is transferred from malonate to the prosthetic group of the biotin protein (MadF) with retention of configuration [2]. Similar to EC, malonyl-S-ACP decarboxylase, which forms part of the biotin-independent malonate decarboxylase (EC, this enzyme also follows on from EC, acetyl-S-ACP:malonate ACP transferase, and results in the regeneration of the acetyl-[acyl-carrier protein] [3].
