title: Inhibition of pyruvate decarboxylase from Z. mobilis by novel analogues of thiamine pyrophosphate: investigating pyrophosphate mimics.
abstract: Replacement of the thiazolium ring of thiamine pyrophosphate with a triazole gives extremely potent inhibitors of pyruvate decarboxylase from Z. mobilis, with K(I) values down to 20 pM; this system was used to explore pyrophosphate mimics and several effective analogues were discovered.
