General annotation (Comments)

Function	The pyruvate dehydrogenase complex catalyzes the overall conversion of pyruvate to acetyl-CoA and CO2. It contains multiple copies of three enzymatic components: pyruvate dehydrogenase (E1), dihydrolipoamide acetyltransferase (E2) and lipoamide dehydrogenase (E3) By similarity.
Catalytic activity	Acetyl-CoA + enzyme N(6)-(dihydrolipoyl)lysine = CoA + enzyme N(6)-(S-acetyldihydrolipoyl)lysine.
Cofactor	Binds 2 lipoyl cofactors covalently By similarity.
Subunit structure	Forms a 24-polypeptide structural core with octahedral symmetry By similarity.
Sequence similarities	Belongs to the 2-oxoacid dehydrogenase family. Contains 2 lipoyl-binding domains.
