High resolution NMR for screening ligand/protein binding.
High resolution NMR spectroscopy has provided a versatile tool for assessing ligand/receptor interactions. NMR-based methods are currently being investigated which may prove valuable for compound screening. These techniques include the use of chemical shift perturbations, the monitoring of translational diffusion and the observation of NOEs. Novel experiments like TROSY and NOE pumping will play significant roles in looking at proteins larger than 30 kDa. New probe technology such as the Cryoprobe could have a significant impact on NMR-based screening for drug discovery by lowering the necessary amount of (15)N-labled protein.
