Equilibrium kinetic network of the villin headpiece in implicit solvent.
We applied the single-replica multiple-state transition-interface sampling method to elucidate the equilibrium kinetic network of the 35-residue-fragment (HP-35) villin headpiece in implicit water at room temperature. Starting from the native Protein Data Bank structure, nine (meta)stable states of the system were identified, from which the kinetic network was built by sampling pathways between...

اندیشمندان و صاحب نظران علوم اجتماعی بر این باورند که مرحله تازه ای در تاریخ جوامع بشری اغاز شده است. ویژگیهای این جامعه نو را می توان پدیده هایی از جمله اقتصاد اطلاعاتی جهانی ، هندسه متغیر شبکه ای، فرهنگ مجاز واقعی ، توسعه حیرت انگیز فناوری های دیجیتال، خدمات پیوسته و نیز فشردگی زمان و مکان برشمرد. از سوی دیگر قدرت به عنوان موضوع اصلی علم سیاست جایگاه مهمی در روابط انسانی دارد، قدرت و بازتولید...
15 صفحه اولCommon structural transitions in explicit-solvent simulations of villin headpiece folding.
Molecular dynamics simulations of protein folding can provide very high-resolution data on the folding process; however, due to computational challenges most studies of protein folding have been limited to small peptides, or made use of approximations such as Gō potentials or implicit solvent models. We have performed a set of molecular dynamics simulations totaling >50 micros on the villin hea...
متن کاملLarge-scale context in protein folding: villin headpiece.
The villin headpiece folds autonomously in vitro forming three alpha-helical regions. Local propensities, however, strongly disfavor the formation of the C-terminal helix because most native residue pairs in that helix are hydrophobic/polar mismatches. Even the N-terminal helix is unfavored according to the AGADIR criterion. Our coarse-grained ab initio simulations reveal three-body correlation...
متن کاملSolvent Sensitivity of Protein Unfolding: Study of Chicken Villin Headpiece Subdomain in Water-Ethanol and Water-DMSO Mixtures
In the present work we study and compare unfolding of a small protein, chicken villin headpiece (HP-36) in two different aqueous binary mixtures, namely water-ethanol (EtOH) and water-dimethyl sulphoxide (DMSO). In both the binary mixtures, HP-36 is found to unfold (fully or partially, depending on the mixture) under ambient conditions, that otherwise requires temperature as high as ~600 K to d...
