Methods for exploring early events in protein folding.
Progress in understanding dynamic aspects of protein folding relies on the continuing development of methods for obtaining more detailed structural information on the transient conformational ensembles that often appear within microseconds of initiating refolding. Advances in rapid mixing and other time-resolved spectroscopic methods have made it possible to explore some of the earliest stages of folding, including the initial formation of compact states, which is determined by the presence of a sequence-specific kinetic barrier, as well as the 'downhill' folding kinetics after the rate-limiting barrier has been crossed.
