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

Forms a 24-polypeptide structural core with octahedral symmetry.

Sequence similarities

Belongs to the 2-oxoacid dehydrogenase family.

Contains 2 lipoyl-binding domains.

Sequence caution

The sequence AAA21599.1 differs from that shown. Reason: Frameshift at positions 229 and 273.
