摘要：

Using a variant of parallel tempering, we study the changes in sampling within a simulation, when the all- atom model is coupled to a Go- like potential. We find that the native structure is not the lowest- energy configuration in the all- atom force field. Adding a Go term deforms the energy landscape in such a way that the native configuration becomes the global minimum but does not lead to faster thermalization.
