General annotation (Comments)

Catalytic activity	ATP + 3-methylcrotonoyl-CoA + HCO3- = ADP + phosphate + 3-methylglutaconyl-CoA.
Cofactor	Biotin. Binds 2 manganese ions per subunit By similarity.
Pathway	Amino-acid degradation; L-leucine degradation; (S)-3-hydroxy-3-methylglutaryl-CoA from 3-isovaleryl-CoA: step 2/3.
Subunit structure	Probably a heterodimer composed of biotin-containing alpha subunits and beta subunits By similarity.
Subcellular location	Mitochondrion matrix Probable.
Induction	Induced during senescence. Ref.6
Sequence similarities	Contains 1 ATP-grasp domain. Contains 1 biotin carboxylation domain. Contains 1 biotinyl-binding domain.
Sequence caution	The sequence ABA99832.2 differs from that shown. Reason: Erroneous gene model prediction.
