We have used time-dependent saturation transferred NOE (STNOE) measurements to assign two downfield resonances in the proton spectrum of an adenosine deaminase-purine riboside mixture. Our results show that this method can be used to detect structural changes that occur upon inhibitor binding to the enzyme and to determine which protons of the bound inhibitor are strongly hydrogen bonded in the complex.
