>TIGR00513 accA acetyl-CoA carboxylase, carboxyl transferase, alpha subunit; InterPro: IPR001095 This entry contains the alpha subunit the acetyl coenzyme A carboxylase complex (). It catalyzes the first step in the synthesis of long-chain fatty acids which involves the carboxylation of acetyl-CoA to malonyl-CoA. The acetyl-CoA carboxylase complex () is a heterohexamer of biotin carboxyl carrier protein, biotin carboxylase and two non-identical carboxyl transferase subunits (alpha and beta) in a 2:2 association . The reaction involves two steps: Biotin carrier protein + ATP + HCO_3^- -> Carboxybiotin carrier protein + ADP + P_i Carboxybiotin carrier protein + Acetyl-CoA -> Malonyl-CoA + Biotin carrier protein ; GO: 0003989 acetyl-CoA carboxylase activity, 0006633 fatty acid biosynthetic process, 0009317 acetyl-CoA carboxylase complex.
