ENZYME entry: EC 1.2.4.2

Accepted Name
Oxoglutarate dehydrogenase (succinyl-transferring).
Alternative Name(s)
2-ketoglutarate dehydrogenase.
2-oxoglutarate dehydrogenase.
2-oxoglutarate: lipoate oxidoreductase.
2-oxoglutarate:lipoamide 2-oxidoreductase (decarboxylating and acceptor- succinylating).
AKGDH.
Alpha-ketoglutarate dehydrogenase.
Alpha-ketoglutaric acid dehydrogenase.
Alpha-ketoglutaric dehydrogenase.
Alpha-oxoglutarate dehydrogenase.
Ketoglutaric dehydrogenase.
OGDC.
Oxoglutarate decarboxylase.
Oxoglutarate dehydrogenase.
Oxoglutarate dehydrogenase (lipoamide).
Reaction catalysed
2-oxoglutarate + [dihydrolipoyllysine-residue succinyltransferase] lipoyllysine <=> [dihydrolipoyllysine-residue succinyltransferase] S-succinyldihydrolipoyllysine + CO(2)
Cofactor(s)
Thiamine diphosphate.
Comment(s)
  • It is a component of the multienzyme 2-oxoglutarate dehydrogenase complex in which multiple copies of it are bound to a core of molecules of EC 2.3.1.61, which also binds multiple copies of EC 1.8.1.4.
  • It does not act on free lipoamide or lipoyllysine, but only on the lipoyllysine residue in EC 2.3.1.61.
