Heterogeneity Even at the Speed Limit of Folding:
Large-scale Molecular Dynamics Study of a Fast-folding Variant of the Villin Headpiece.
Non-technical summary:This paper describes the first set of results generated using the SMP clients. The main advantage of using SMP for these sorts of calculations is that the amount of computation that one client can do is several times larger than the traditional clients. This means that our simulations can get many times longer that before; in fact, this has allowed us to generate several hundred folding trajectories of the fastest-folding protein known, the HP35-NleNle variant of the villin headpiece subdomain. In this paper, because our simulation time scales compare well to the 700-nanosecond experimental folding time of this protein, AND we've generated enough trajectories to get good statistics, we can shed some light on the experimental results. To summarize the result, the first helix of the protein was thought to be highly structured in the unfolded state of the protein; we've suggested that structure in this part of the molecule is not enough to lead to fast folding, and that longer time scales than the 700-ns mark may be present in this system.
