Transferred-NOE experiments ( 94PROG517) provide conformational information of bound ligands from intra-ligand NOE data in weakly-binding rapid exchange ligand/protein complexes and also to locate the corresponding binding sites. When a small molecule binds a large molecule suchas a protein, the numerical sign and magnitudes of the NOEs change. Several examples include:
  • Enzyme-substrate/inhibitor ( 97PNAS4383, 97BIO2353, 98BIO3020)
  • Protein-carbohydrate complexes ( 98JACS1309, 97JACS1727, 00CRS50)
  • Protein-peptide complexes ( 98BIO867, 98BIO9793)
  • The accuracy of the peptide-protein structures obtained from transferred-NOE data has been studied and simulated ( 00JB17-17) and the effect of intermolecular relaxation evaluated ( 02JB303-22) .

    This method have been also used for screening purposes of mixtures of small, biologically-active molecules in the presence of large molecules, like proteins ( 97EJB705-246, 99ANG98, and 00JMC2093).

    Variants of the NOESY pulse sequence to minimize undesired ZQC have been proposed ( 00MRC315).
