Movement of the Intermediate and Rate Determining Transition State of Barnase on the Energy Landscape with Changing Temperature
Barnase folds cooperatively via an intermediate, followed by a rate-limiting transition state. We have probed possible movements of the intermediate and transition state on the energy landscape with changing temperature, from the temperature dependence of -values. These measure interaction energies at the level of individual residues. The results suggest that single destabilizing mutations can red
