3-Methylcrotonyl-CoA or β-Methylcrotonyl-CoA is an
intermediate in the metabolism of
leucine
Leucine (symbol Leu or L) is an essential amino acid that is used in the biosynthesis of proteins. Leucine is an α-amino acid, meaning it contains an α- amino group (which is in the protonated −NH3+ form under biological conditions), an α- ...

It is found in mitochondria, where it is formed from
isovaleryl-coenzyme A by
isovaleryl coenzyme A dehydrogenase. It then reacts with CO
2 to yield
3-Methylcrotonyl-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 ...
