CC   -!- FUNCTION: Lipoamide dehydrogenase is a component of the glycine
CC       cleavage system as well as of the alpha-ketoacid dehydrogenase
CC       complexes (By similarity).
CC   -!- CATALYTIC ACTIVITY: Protein N(6)-(dihydrolipoyl)lysine + NAD(+) =
CC       protein N(6)-(lipoyl)lysine + NADH.
CC   -!- COFACTOR: Binds 1 FAD per subunit (By similarity).
CC   -!- SUBUNIT: Homodimer (By similarity).
CC   -!- SUBCELLULAR LOCATION: Cytoplasm (By similarity).
CC   -!- MISCELLANEOUS: The active site is a redox-active disulfide bond
CC       (By similarity).
CC   -!- SIMILARITY: Belongs to the class-I pyridine nucleotide-disulfide
CC       oxidoreductase family.
