abstract = {Intrinsically disordered proteins (IDPs) are involved in a
wide variety of physiological and pathological processes and
are best described by ensembles of rapidly interconverting
conformers. Using fast field cycling relaxation measurements
we here show that the IDP α-synuclein as well as a variety
of other IDPs undergoes slow reorientations at time scales
comparable to folded proteins. The slow motions are not
perturbed by mutations in α-synuclein, which are related to
genetic forms of Parkinson's disease, and do not depend on
secondary and tertiary structural propensities.
Ensemble-based hydrodynamic calculations suggest that the
time scale of the underlying correlated motion is largely
determined by hydrodynamic coupling between locally rigid
segments. Our study indicates that long-range correlated
dynamics are an intrinsic property of IDPs and offers a
general physical mechanism of correlated motions in highly
flexible biomolecular systems.},
