CC -!- FUNCTION: Lipoamide dehydrogenase is a component of the alpha-ketoacid
CC dehydrogenase complexes. Catalyzes the reoxidation of dihydrolipoyl
CC groups which are covalently attached to the lipoate acyltransferase
CC components (E2) of the complexes (By similarity). {ECO:0000250}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=(R)-N(6)-dihydrolipoyl-L-lysyl-[protein] + NAD(+) = (R)-N(6)-
CC lipoyl-L-lysyl-[protein] + H(+) + NADH; Xref=Rhea:RHEA:15045,
CC Rhea:RHEA-COMP:10474, Rhea:RHEA-COMP:10475, ChEBI:CHEBI:15378,
CC ChEBI:CHEBI:57540, ChEBI:CHEBI:57945, ChEBI:CHEBI:83099,
CC ChEBI:CHEBI:83100; EC=1.8.1.4;
CC -!- COFACTOR:
CC Name=FAD; Xref=ChEBI:CHEBI:57692; Evidence={ECO:0000250};
CC Note=Binds 1 FAD per subunit. {ECO:0000250};
CC -!- SUBUNIT: Homodimer. Part of the PDH complex, consisting of multiple
CC copies of AceE (E1), DlaT (E2) and Lpd (E3), and of the BCKADH complex,
CC consisting of multiple copies of BkdA/BkdB (E1), BkdC (E2) and Lpd
CC (E3). {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000305}.
CC -!- MISCELLANEOUS: The active site is a redox-active disulfide bond.
CC -!- SIMILARITY: Belongs to the class-I pyridine nucleotide-disulfide
CC oxidoreductase family. {ECO:0000305}.
