DOI: 10.1126/sciadv.aax2348
Abstract: Molecular simulation and NMR reveal how intrinsically disordered proteins move in synergy with their surrounding environment. Protein and water dynamics have a synergistic relationship, which is particularly important for intrinsically disordered proteins (IDPs), although the… read more here.
