Fig. 3.
The logarithm of the (A) unfolding and (B) refolding rates of A7C/N59C src SH3 (black) and R19C/N59C src SH3 (red) obtained from force-jump/force-quench experiments were plotted as a function of force to obtain the unfolding and refolding distances to the transition state according to Bell’s model. Typical unfolding and refolding traces are shown in the inset.
