Derived from the components MadC and MadD of the anaerobic bacterium Malonomonas rubra, this enzyme is a component of EC 7.2.4.4, biotin-dependent malonate decarboxylase. The carboxy group is transferred from malonate to the cofactor of the biotin protein (MadF) with retention of configuration . Similar to EC 4.1.1.87, malonyl-S-ACP decarboxylase, which forms part of the biotin-independent malonate decarboxylase (EC 4.1.1.88), this enzyme also follows on from EC 2.3.1.187, acetyl-S-ACP:malonate ACP transferase, and results in the regeneration of the acetyl-[acyl-carrier protein] .
The expected taxonomic range for this enzyme is: Malonomonas rubra

Substrates: enzyme catalyzes the transfer of acyl carrier protein from acetyl acyl carrier protein and malonate to yield malonyl acyl carrier protein and acetate. Malonate is thus activated on the enzyme by exchange for the catalytically important enzyme-bound acetyl thioester residues Products: -
