The degradation of L-leucine starts either in the mitochondria, the cytosol or the chloroplast. L-leucine reacts with 2-oxoglutarate through a branch-chain amino acid aminotransferase resulting in the release of ketoleucine and glutamate. Ketoleucine reacts with coenzyme a through a NAD dependent branched chain keto-acid dehydrogenase complex resulting in the release of NADH, carbon dioxide and isovaleryl-CoA. Isovaleryl-CoA reacts with an oxidized electron flavoprotein resulting in the release of a reduced flavoprotein and a methylcrotonyl-CoA. The latter reacts with ATP and hydrogen carbonate through a 3-methylcrotonyl-CoA carboxylase resulting in the release of phosphate, ADP, hydrogen ion and 3-methylglutaconyl-CoA. The latter compound reacts with water through a methylglutaconyl-CoA hydratase resulting in the release of hydroxy-3-methylglutaryl-CoA. The latter reacts with a hydroxymethylglutaryl-CoA lyase resulting in the release of acetyl-CoA and acetoacetate.
