Kinetic analysis of protein aggregation monitored by real-time 2D solid-state NMR spectroscopy
Kinetic analysis of protein aggregation monitored by real-time 2D solid-state NMR spectroscopy
Abstract It is shown that real-time 2D solid-state NMR can be used to obtain kinetic and structural information about the process of protein aggregation. In addition to the incorporation of kinetic information involving intermediate states, this approach can offer atom-specific resolution for all detectable species. The analysis was carried out using experimental data obtained during aggregation of the 10.4 kDa Crh protein, which has been shown to involve a partially unfolded intermediate...

Real-time NMR spectroscopy developed to a generally applicable method to follow protein folding reactions. It combines the access to high resolution data with kinetic experiments allowing very detailed insights into the development of the protein structure during different steps of folding. The present review concentrates mainly on the progress of real-time NMR...

At low ionic strength, apoplastocyanin forms an unfolded state under non-denaturing conditions. The refolding of this state is sufficiently slow to allow real-time NMR experiments to be performed. Folding of apoplastocyanin, initiated by the addition of salt and followed by real-time 2D 1H-15N...

Structural studies in proteases have been hampered because of their inherent autolytic function. However, since autolysis is known to be mediated via protein unfolding, careful monitoring of the autolytic reaction has the potential to throw light on the...
