CC -!- FUNCTION: Lipoamide dehydrogenase is a component of the glycine
CC cleavage system as well as of the alpha-ketoacid dehydrogenase
CC complexes. The pyruvate dehydrogenase complex contains multiple copies
CC of three enzymatic components: pyruvate dehydrogenase (E1),
CC dihydrolipoamide acetyltransferase (E2) and lipoamide dehydrogenase
CC (E3).
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;
CC Note=Binds 1 FAD per subunit.;
CC -!- SUBUNIT: Homodimer. {ECO:0000269|PubMed:10806386}.
CC -!- SUBCELLULAR LOCATION: Mitochondrion matrix.
CC -!- MASS SPECTROMETRY: Mass=49753; Mass_error=5; Method=Electrospray;
CC Evidence={ECO:0000269|PubMed:8546688};
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}.
