IUBMB Comments

Contains thiamine diphosphate. It is a component of the multienzyme 2-oxoglutarate dehydrogenase complex, EC 1.2.1.105, in which multiple copies of it are bound to a core of molecules of EC 2.3.1.61, dihydrolipoyllysine-residue succinyltransferase, which also binds multiple copies of EC 1.8.1.4, dihydrolipoyl dehydrogenase. It does not act on free lipoamide or lipoyllysine, but only on the lipoyllysine residue in EC 2.3.1.61.

The expected taxonomic range for this enzyme is: Bacteria, Eukaryota, Archaea
