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 3 enzymatic components: 2-oxoglutarate dehydrogenase (E1), dihydrolipoamide succinyltransferase (E2) and lipoamide dehydrogenase (E3). Ref.1

Catalytic activity

Succinyl-CoA + enzyme N(6)-(dihydrolipoyl)lysine = CoA + enzyme N(6)-(S-succinyldihydrolipoyl)lysine.

Cofactor

Binds 1 lipoyl cofactor covalently By similarity.

Pathway

Amino-acid degradation; L-lysine degradation via saccharopine pathway; glutaryl-CoA from L-lysine: step 6/6.

Subunit structure

Forms a 24-polypeptide structural core with octahedral symmetry By similarity.

Subcellular location

Mitochondrion Ref.1.

Sequence similarities

Belongs to the 2-oxoacid dehydrogenase family.

Contains 1 lipoyl-binding domain.
