| Abstract |
The funneled landscape perspective has served as a conceptual background for understanding protein folding, but the explicit characterization of the protein free energy landscape from fully microscopic approaches remains a challenge. Here, we propose a simple and direct construction method of the landscape based on all-atom simulations. We apply it to representative alpha-helical (HP-35) and beta-sheet (WW domain) proteins and to an intrinsically disordered protein (pKID) that folds upon binding to its partner (KIX) to extract common and distinctive characteristics of their landscapes. We find that pKID, as well as HP-35 and WW domain, possesses the funneled landscape, but its landscape is not funneled enough to allow the folding by itself; nevertheless, the landscape of pKID becomes funneled enough upon binding to KIX. The method proposed here is applicable to any atomistic simulations, and will be effective in deriving molecular insights behind a variety of biomolecular processes. |
