New experimental methods permit observation of protein folding and unfolding on the previously inaccessible nanosecond-microsecond timescale. These studies are beginning to establish times for the elementary motions in protein folding - secondary structure and loop formation, local hydrophobic collapse, and global collapse to the compact denatured state. They permit an estimate of about one microsecond...
Understanding how proteins fold is one of the central problems in biochemistry. A new generation of kinetic experiments has emerged to investigate the mechanisms of protein folding on the previously inaccessible submillisecond time scale. These experiments provide the first glimpse of processes such as secondary structure formation, local hydrophobic collapse, global collapse to compact denatured...
