Group epitope mapping by saturation transfer difference NMR to identify segments of a ligand in direct contact with a protein receptor.

M Mayer et al.

Journal of the American Chemical Society, 123(25), 6108-6117 (2001-06-21)

A protocol based on saturation transfer difference (STD) NMR spectra was developed to characterize the binding interactions at an atom level, termed group epitope mapping (GEM). As an example we chose the well-studied system of galactose binding to the 120-kDa
