obsolete mitochondrial branched-chain alpha-keto acid dehydrogenase complex (obsolete GO:0160120)
OBSOLETE. A mitochondrial complex that catalyzes the oxidative decarboxylation of branched-chain alpha-keto acids derived from L-leucine, L-isoleucine, and L-valine to branched-chain acyl-CoAs. The complex is organized around a 24-meric cubic core of the dihydrolipoyl transacylase (E2) with multiple (about 6 to 12) copies of the branched-chain alpha-ketoacid dehydrogenase (E1, consisting of alpha and beta subunits), about 6 copies of the dimeric dihydrolipoyl dehydrogenase (E3), and a small number of copies of the E1-specific kinase and phosphatase.
