Abstract
NMR has proven to be an invaluable technique for identifying and characterizing ligand interactions with biomolecules. NMR-based detection of ligand binding to protein targets is described. Specifically, the use of the WaterLOGSY NMR experiment to screen mixtures of compounds from a fragment library for binding to influenza H5 hemagglutinin is detailed.

An NMR strategy for fragment-based ligand screening utilizing a paramagnetic lanthanide probe
Abstract A nuclear magnetic resonance-based ligand screening strategy utilizing a paramagnetic lanthanide probe is presented. By fixing a paramagnetic lanthanide ion to a target protein, a pseudo-contact shift (PCS) and a paramagnetic relaxation enhancement (PRE) can be observed for both the target protein and its bound ligand. Based on PRE and PCS information, the bound ligand is then screened from the compound library and the structure of the ligandâ??protein complex is determined. PRE is an...
