Comment
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 prosthetic group of the biotin protein (MadF) with retention of configuration [2]. 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] [3].
History
EC 2.1.3.10 created 2008, modified 2018
