Contains thiamine diphosphate. It is a component (in multiple copies) of the multienzyme pyruvate dehydrogenase complex in which it is bound to a core of molecules of EC 126.96.36.199, dihydrolipoyllysine-residue acetyltransferase, which also binds multiple copies of EC 188.8.131.52, dihydrolipoyl dehydrogenase. It does not act on free lipoamide or lipoyllysine, but only on the lipoyllysine residue in EC 184.108.40.206.
