ID 2.3.1.187 DE acetyl-S-ACP:malonate ACP transferase. AN ACP transferase. AN malonate/acetyl-CoA transferase. CA acetyl-[ACP] + malonate = acetate + malonyl-[ACP]. CC -!- This is the first step in the catalysis of malonate decarboxylation CC and involves the exchange of an acetyl thioester residue bound to the CC activated acyl-carrier protein (ACP) subunit of the malonate CC decarboxylase complex for a malonyl thioester residue. CC -!- This enzyme forms the alpha subunit of the multienzyme complexes CC EC 4.1.1.88 and EC 7.2.4.4. CC -!- Can also use acetyl-CoA as a substrate but more slowly. DR O06924, MADA_MALRU ; //
