Physics of protein folding
Protein physics is grounded on three fundamental experimental facts: protein, this long heteropolymer, has a well defined compact three-dimensional structure; this structure can spontaneously arise from the unfolded protein chain in appropriate environment; and this structure is separated from the unfolded state of the chain by the “all-or-none” phase transition, which ensures robustness of pro...
متن کاملChemical physics of protein folding.
I n 2008, to the consternation of some, one of the editors of this special issue on the “Chemical Physics of Protein Folding,” was quoted as saying, “What was called the protein folding problem 20 years ago is solved” (1). One purpose of this special issue is to drive home this point. The other, more important purpose is to illustrate how workers on the protein folding problem, by moving beyond...
متن کاملProtein Folding: A Perspective From Statistical Physics
In this paper, we introduce an approach to the protein folding problem from the point of view of statistical physics. Protein folding is a stochastic process by which a polypeptide folds into its characteristic and functional 3D structure from random coil. The process involves an intricate interplay between global geometry and local structure, and each protein seems to present special problems....
متن کاملProtein Stability, Folding, Disaggregation and Etiology of Conformational Malfunctions
Estimation of protein stability is important for many reasons: first providing an understanding of the basic thermodynamics of the process of folding, protein engineering, and protein stability plays important role in biotechnology especially in food and protein drug design. Today, proteins are used in many branches, including industrial processes, pharmaceutical industry, and medical fields. A...
متن کاملStatistical physics of RNA folding.
We discuss the physics of RNA as described by its secondary structure. We examine the static properties of a homogeneous RNA model that includes pairing and base stacking energies as well as entropic costs for internal loops. For large enough loop costs the model exhibits a thermal denaturation transition which we analyze in terms of the radius of gyration. We point out an inconsistency in the ...
