[1]	NUCLEOTIDE SEQUENCE [MRNA]. Keightley J.A., Shang L., Kinter M.; "2D gel analysis of the proteomic adaptation of a mammalian cell line to oxidative stress reveals changes in the expression of metabolically relevant enzymes."; Submitted (AUG-2002) to the EMBL/GenBank/DDBJ databases.

Comments

FUNCTION: Lipoamide dehydrogenase is a component of the glycine cleavage system as well as of the alpha-ketoacid dehydrogenase complexes (By similarity).
CATALYTIC ACTIVITY: Protein N⁶-(dihydrolipoyl)lysine + NAD⁺ = protein N⁶-(lipoyl)lysine + NADH.
COFACTOR: Binds 1 FAD per subunit (By similarity).
SUBUNIT: Homodimer. Eukaryotic pyruvate dehydrogenase complexes are organized about a core consisting of the oligomeric dihydrolipoamide acetyl-transferase, around which are arranged multiple copies of pyruvate dehydrogenase, dihydrolipoamide dehydrogenase and protein X bound by non-covalent bonds (By similarity).
SUBCELLULAR LOCATION: Mitochondrion matrix (By similarity).
MISCELLANEOUS: The active site is a redox-active disulfide bond.
SIMILARITY: Belongs to the class-I pyridine nucleotide-disulfide oxidoreductase family.
