>TIGR00515 accD acetyl-CoA carboxylase, carboxyl transferase, beta subunit; InterPro: IPR000438 Fatty acid synthesis involves a set of reactions, commencing with carboxylation of acetyl-CoA to malonyl-CoA. This is an irreversible reaction, catalysed by the acetyl-CoA carboxylase complex (6.4.1.2 from EC); 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 In the first step, biotin carboxylase catalyses the carboxylation of the carrier protein to form an intermediate. Next, the transcarboxylase complex transfers the carboxyl group from the intermediate to acetyl-CoA forming malonyl-CoA.; GO: 0003989 acetyl-CoA carboxylase activity, 0006633 fatty acid biosynthetic process, 0009317 acetyl-CoA carboxylase complex.
