Short summary
Unlike rigid folded proteins, intrinsically disordered proteins (IDPs) exist as an ensemble of dynamically interconverting structures. Cross-correlated spin-relaxation experiments are particularly suited to characterize the structural dynamics of IDPs as they encode a protein's structural memory. By translating diffusion models of folded proteins to segmental motions in IDPs, we define and assess a sensitive experimental measure for the presence of anisotropic dynamics in the protein backbone.
