CC   -!- FUNCTION: This protein is a component of the acetyl coenzyme A
CC       carboxylase complex; first, biotin carboxylase catalyzes the
CC       carboxylation of the carrier protein and then the transcarboxylase
CC       transfers the carboxyl group to form malonyl-CoA. {ECO:0000250}.
CC   -!- PATHWAY: Lipid metabolism; fatty acid biosynthesis.
CC   -!- SUBCELLULAR LOCATION: Plastid, chloroplast.
