Comment typeDescription
Catalytic ActivityATP + acetyl-CoA + HCO(3)(-) = ADP + phosphate + malonyl-CoA. {ECO:0000255|HAMAP-Rule:MF_01395}.
CofactorName=Zn(2+); Xref=ChEBI:CHEBI:29105; Evidence={ECO:0000255|HAMAP-Rule:MF_01395}; Note=Binds 1 zinc ion per subunit. {ECO:0000255|HAMAP- Rule:MF_01395};
FunctionComponent of the acetyl coenzyme A carboxylase (ACC) complex. Biotin carboxylase (BC) catalyzes the carboxylation of biotin on its carrier protein (BCCP) and then the CO(2) group is transferred by the transcarboxylase to acetyl-CoA to form malonyl- CoA. {ECO:0000255|HAMAP-Rule:MF_01395}.
PathwayLipid metabolism; malonyl-CoA biosynthesis; malonyl-CoA from acetyl-CoA: step 1/1. {ECO:0000255|HAMAP-Rule:MF_01395}.
Rna EditingModified_positions=265 {ECO:0000269|PubMed:11078738};
SimilarityBelongs to the AccD/PCCB family. {ECO:0000255|HAMAP- Rule:MF_01395}.
Subcellular LocationPlastid, chloroplast membrane; Peripheral membrane protein. Plastid, chloroplast stroma.
SubunitAcetyl-CoA carboxylase is a heterohexamer composed of biotin carboxyl carrier protein, biotin carboxylase and 2 subunits each of ACCase subunit alpha and ACCase plastid-coded subunit beta (accD). {ECO:0000269|PubMed:10759501}.
Tissue SpecificityAccumulates in fatty acids synthesizing tissues such as embryos, expanding leaves, flower buds, flowers, and developing siliques. {ECO:0000269|PubMed:10759501}.
