Comments
  • FUNCTION: The branched-chain alpha-keto dehydrogenase complex catalyzes the overall conversion of alpha-keto acids to acyl-CoA and CO(2). It contains multiple copies of three enzymatic components: branched-chain alpha-keto acid decarboxylase (E1), lipoamide acyltransferase (E2) and lipoamide dehydrogenase (E3) (By similarity).
  • CATALYTIC ACTIVITY: 3-methyl-2-oxobutanoate + [dihydrolipoyllysine-residue (2-methylpropanoyl)transferase] lipoyllysine = [dihydrolipoyllysine-residue (2-methylpropanoyl)transferase] S-(2-methylpropanoyl)dihydrolipoyllysine + CO2.
  • COFACTOR: Thiamine pyrophosphate (By similarity).
  • SUBUNIT: Heterotetramer of alpha and beta chains (By similarity).
  • SUBCELLULAR LOCATION: Mitochondrion matrix (By similarity).
  • MISCELLANEOUS: Bound potassium ions stabilize the protein structure (By similarity).
  • SIMILARITY: Belongs to the BCKDHA family.
