Abstract

Saturation transfer difference (STD) NMR is a technique that provides information on the intermolecular interfaces of heterogenous complexes by cross-saturation from one molecule to the other. In this case, selective saturation of protein protons is applied, and the cross-relaxation to the RNA sample results in a reduction of the peak intensities in the measured H1–H1 NOESY spectrum. This allows for a relatively rapid and simple method of identifying the protein binding interface of an RNA with assigned chemical shift data.
