All-atom generalized-ensemble simulations of small proteins

We give an overview of some generalized-ensemble techniques that have proven successful in all-atom simulations of proteins. We show that these techniques enable efficient investigations of secondary structure formation and folding in peptides and small proteins. Results are presented for various alanine-based artificial peptides and a small protein, the 36-residued villin headpiece subdomain (HP-36). Our results indicate that all-atom simulations of proteins may be more restricted by the accuracy of the present energy functions than by the efficiency of the search algorithms. © 2003 Elsevier Inc.
