Comments

Comment Type Description
Catalytic Activity ATP + acetyl-CoA + HCO(3)(-) = ADP + phosphate + malonyl-CoA.
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). {ECO:0000250}.
Pathway Lipid metabolism; malonyl-CoA biosynthesis; malonyl-CoA from acetyl-CoA: step 1/1.
Similarity Belongs to the AccA family. {ECO:0000305}.
Subcellular Location Plastid, chloroplast inner membrane {ECO:0000269|PubMed:10759501, ECO:0000269|PubMed:12766230, ECO:0000269|PubMed:12938931, ECO:0000269|PubMed:15028209, ECO:0000269|PubMed:16207701, ECO:0000269|PubMed:18431481}; Peripheral membrane protein {ECO:0000269|PubMed:10759501, ECO:0000269|PubMed:12766230, ECO:0000269|PubMed:12938931, ECO:0000269|PubMed:15028209, ECO:0000269|PubMed:16207701, ECO:0000269|PubMed:18431481}; Stromal side {ECO:0000269|PubMed:10759501, ECO:0000269|PubMed:12766230, ECO:0000269|PubMed:12938931, ECO:0000269|PubMed:15028209, ECO:0000269|PubMed:16207701, ECO:0000269|PubMed:18431481}.
Subunit Acetyl-CoA carboxylase is a heterohexamer composed of biotin carboxyl carrier protein, biotin carboxylase and two subunits each of ACCase subunit alpha and ACCase plastid-coded subunit beta (accD). {ECO:0000269|PubMed:10759501}.
Tissue Specificity Accumulates in fatty acids synthesizing tissues such as embryos, expanding leaves, flower buds, flowers, and developing siliques. {ECO:0000269|PubMed:10759501}.
