General annotation (Comments)

Function

The 2-oxoglutarate dehydrogenase complex catalyzes the overall conversion of 2-oxoglutarate to succinyl-CoA and CO2. It contains multiple copies of three enzymatic components: 2-oxoglutarate dehydrogenase (E1), dihydrolipoamide succinyltransferase (E2) and lipoamide dehydrogenase (E3) By similarity.

Catalytic activity

2-oxoglutarate + [dihydrolipoyllysine-residue succinyltransferase] lipoyllysine = [dihydrolipoyllysine-residue succinyltransferase] S-succinyldihydrolipoyllysine + CO2.

Cofactor

Thiamine pyrophosphate By similarity.

Subunit structure

Homodimer By similarity.

Sequence similarities

Belongs to the alpha-ketoglutarate dehydrogenase family.

Sequence caution

The sequence AAC23308.1 differs from that shown. Reason: Erroneous initiation.
