Overview of BCAA catabolic pathway

Overview of BCAA catabolic pathway. The BCAAs undergo transamination that is catalyzed by the branched-chain aminotransferase (BCAT) and requires α- ketoglutarate, leading to the production of the α-ketoacids KIC, KMV, and KIV. These intermediates then undergo oxidative decarboxylation, catalyzed by the BCKAD complex.Abbreviations: KIC, α-ketoisocaproic acid; KIV, α-ketoisovaleric acid; KMV, α-keto-β-methylvaleric acid; Glu, glutamate; BCAAs, branched-chain amino acids; BCKAD, branched-chain α-ketoacid dehydrogenase.
