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
