Methylcrotonyl-CoA carboxylase
CLASS OF ENZYMES
Methylcrotonoyl-CoA carboxylase; MCCC2; MCCC1; 3-methylcrotonyl-CoA carboxylase; EC 6.4.1.4; 3-methylcrotonoyl-CoA:carbon-dioxide ligase (ADP-forming); MC-CoA carboxylase
Methylcrotonyl CoA carboxylase (, MCC) (3-methylcrotonyl CoA carboxylase, methylcrotonoyl-CoA carboxylase) is a biotin-requiring enzyme located in the mitochondria. MCC uses bicarbonate as a carboxyl group source to catalyze the carboxylation of a carbon adjacent to a carbonyl group performing the fourth step in processing leucine, an essential amino acid.
