EC Tree
IUBMB Comments
This enzyme is a multi-domain polypeptide that catalyses three different activities - a biotin carboxyl-carrier protein (BCCP), a biotin carboxylase that catalyses the transfer of a carboxyl group from hydrogencarbonate to the biotin molecule carried by the carrier protein, and the transfer of the carboxyl group from biotin to acetyl-CoA, forming malonyl-CoA. In some organisms these activities are catalysed by separate enzymes (see EC 6.3.4.14, biotin carboxylase, and EC 2.1.3.15, acetyl-CoA carboxytransferase). The carboxylation of the carrier protein requires ATP, while the transfer of the carboxyl group to acetyl-CoA does not.

acetyl-CoA carboxylase is a multifunctional biotin-dependent enzyme that catalyzes the first committed and regulated step in fatty acid biosynthesis in bacteria via a two-step reaction. Biotin carboxylase, EC 6.3.4.14, catalyzes the first half-reaction, which is an ATP-dependent carboxylation of biotin to form carboxybiotin. The second half-reaction is catalyzed by carboxyltransferase, EC 6.4.1.2, which transfers the carboxyl group from carboxybiotin to acetyl-CoA to generate malonyl-CoA
