Sequence status	Complete.
Sequence processing	The displayed sequence is further processed into a mature form.
Protein existence	Evidence at transcript level.

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).
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	20 to 30 alpha(2)-beta2 tetramers of E1 + 6 homodimers of E3 + 60 copies of E2.
Subcellular location	Mitochondrion matrix.
Sequence similarities	Belongs to the 2-oxoacid dehydrogenase family. Contains 2 lipoyl-binding domains.
Sequence caution	The sequence AAA16511.1 differs from that shown. Reason: Frameshift at positions 577 and 585.
