MCCC2(Methylcrotonoyl-CoA carboxylase beta chain, mitochondrial) is also named as MCCB and belongs to the AccD/PCCB family. The putative 563-amino acid polypeptide has a calculated molecular mass of 61 kD and contains an N-terminal mitochondrial targeting sequence(PMID:11181649). It catalyzes carboxylation of 3 methylcrotonyl COA to form 3 methylglutaconyl-COA and is probably a dodecamer composed of six biotin-containing alpha subunits and six beta subunits. Defects in MCCC2 are the cause of methylcrotonoyl-CoA carboxylase 2 deficiency (MCC2D).
