Józef Lewandowski in collaboration with Lyndon Emsley (EPFL, Lausanne/ENS-Lyon) and Martin Blackledge (IBS, Grenoble) reports in Science on a direct observation of hierarchy of protein and solvent motions in protein conformational energy landscape. The findings of the study employing a series of variable temperature magic angle spinning multinuclear NMR relaxation measurements on a nanocrystalline protein reconcile divergent interpretations from techniques that are individually sensitive to dynamic phenomena occurring on different time scales and at different locations in protein-solvent systems.
