Abstract
NMR spectroscopy is a powerful tool for studying molecular dynamics at atomic resolution simultaneously for a large number of nuclear sites. In this communication, we combine two powerful NMR techniques, relaxation-dispersion NMR and real-time NMR, in order to obtain unprecedented information on the conformational exchange dynamics present in short-lived excited protein states, such as those transiently accumulated during protein folding. We demonstrate the feasibility of the approach for the amyloidogenic protein ?2-microglobulin that folds via an intermediate state which is believed to be responsible for the onset of the aggregation process leading to amyloid formation.
