CC   -!- FUNCTION: Component of the acetyl coenzyme A carboxylase (ACC) complex.
CC       Biotin carboxylase (BC) catalyzes the carboxylation of biotin on its
CC       carrier protein (BCCP) and then the CO(2) group is transferred by the
CC       transcarboxylase to acetyl-CoA to form malonyl-CoA. {ECO:0000255|HAMAP-
CC       Rule:MF_01395}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=acetyl-CoA + N(6)-carboxybiotinyl-L-lysyl-[protein] = malonyl-
CC         CoA + N(6)-biotinyl-L-lysyl-[protein]; Xref=Rhea:RHEA:54728,

CC         Evidence={ECO:0000255|HAMAP-Rule:MF_01395};
CC   -!- COFACTOR:
CC       Name=Zn(2+); Xref=ChEBI:CHEBI:29105;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_01395};
CC       Note=Binds 1 zinc ion per subunit. {ECO:0000255|HAMAP-Rule:MF_01395};
CC   -!- PATHWAY: Lipid metabolism; malonyl-CoA biosynthesis; malonyl-CoA from
CC       acetyl-CoA: step 1/1. {ECO:0000255|HAMAP-Rule:MF_01395}.
CC   -!- SUBUNIT: Acetyl-CoA carboxylase is a heterohexamer composed of biotin
CC       carboxyl carrier protein (AccB), biotin carboxylase (AccC) and two
CC       subunits each of ACCase subunit alpha (AccA) and ACCase subunit beta
CC       (AccD). {ECO:0000255|HAMAP-Rule:MF_01395}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_01395}.
CC   -!- SIMILARITY: Belongs to the AccD/PCCB family. {ECO:0000255|HAMAP-
CC       Rule:MF_01395}.
