General annotation (Comments)

Function	Lipoamide dehydrogenase is a component of the alpha-ketoacid dehydrogenase complexes By similarity. Malfunction of this protein blocks the progression of cell cycle from G1 to S phase.
Catalytic activity	Protein N(6)-(dihydrolipoyl)lysine + NAD+ = protein N(6)-(lipoyl)lysine + NADH.
Cofactor	Binds 1 FAD per subunit By similarity.
Subunit structure	Homodimer By similarity.
Subcellular location	Mitochondrion matrix Potential.
Miscellaneous	The active site is a redox-active disulfide bond.
Sequence similarities	Belongs to the class-I pyridine nucleotide-disulfide oxidoreductase family.
