FUNCTION: Component of the acetyl coenzyme A carboxylase (ACC) complex. First, biotin carboxylase catalyzes the carboxylation of biotin on its carrier protein (BCCP) and then the CO(2) group is transferred by the carboxyltransferase to acetyl-CoA to form malonyl-CoA (By similarity).
CATALYTIC ACTIVITY: ATP + acetyl-CoA + HCO₃^- = ADP + phosphate + malonyl-CoA.
PATHWAY: Lipid metabolism; malonyl-CoA biosynthesis; malonyl-CoA from acetyl-CoA: step 1/1 .
SUBUNIT: Acetyl-CoA carboxylase is an heterohexamer composed of biotin carboxyl carrier protein (accB), biotin carboxylase (accC) and two subunits each of ACCase subunit alpha (accA) and ACCase subunit beta (accD) (By similarity).
SUBCELLULAR LOCATION: Cytoplasm (By similarity).
SIMILARITY: Belongs to the accA family.
