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 184.108.40.206, dihydrolipoyllysine-residue acetyltransferase, which also binds multiple copies of EC 220.127.116.11, dihydrolipoyl dehydrogenase. It does not act on free lipoamide or lipoyllysine, but only on the lipoyllysine residue in EC 18.104.22.168.
