Protein attributes

Sequence length	391 AA.
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	Pyruvate + [dihydrolipoyllysine-residue acetyltransferase] lipoyllysine = [dihydrolipoyllysine-residue acetyltransferase] S-acetyldihydrolipoyllysine + CO2.
Cofactor	Thiamine pyrophosphate.
Enzyme regulation	E1 activity is regulated by phosphorylation (inactivation) and dephosphorylation (activation) of the alpha subunit.
Subunit structure	Tetramer of 2 alpha and 2 beta subunits.
Subcellular location	Mitochondrion Probable.
Tissue specificity	Testis.
