Available in PDF, EPUB and Kindle. Book excerpt: How a protein folds from an unstructured heteropolymer into a unique native structure is an important unanswered question in the field of molecular biophysics. In recent years, there have been a number of experiments and computer simulations that have provided insight into the mechanism by which folding occurs. Most of these experiments and simulations measure the dynamics of proteins in infinite dilution. However, bulk solvent is different from the cellular environment in which proteins truly fold. In vivo, protein dynamics occur in the context of the crowded cellular milieu as well as in confined spaces such as the chaperonin cavity, the proteosome, the ribosome exit tunnel, the translocon, etc. When considering these factors it is reasonable to assume that proteins may experience different microenvironments when folding in vivo than in bulk, and these differences may constitute a significant piece of the folding puzzle. Here we show via molecular dynamics simulation, that the presence of solvent when confining a mini- protein affects the probability and mechanism of folding. In a separate study, we use computer simulation to calculate the physical properties of water confined to the ribosome exit tunnel. We find that this solvent is quite different from bulk water, possessing a highly heterogeneous free energy landscape containing extensive water structure, areas of reduced solvent entropy. Finally we show that the foldase activity of GroEL cavity mutants is highly correlated with the hydrophilicy of the inner cavity.

Download or read book Protein Folding written by Charis Ghelis and published by Academic Press. This book was released on 2012-12-02 with total page 580 pages. Available in PDF, EPUB and Kindle. Book excerpt: Protein Folding aims to collect the most important information in the field of protein folding and probes the main principles that govern formation of the three-dimensional structure of a protein from a nascent polypeptide chain, as well as how the functional properties appear. This text is organized into three sections and consists of 15 chapters. After an introductory chapter where the main problems of protein folding are considered at the cellular level in the context of protein biosynthesis, the discussion turns to the conformation of native globular proteins. Definitions and rules of nomenclature are given, including the structural organization of globular proteins deduced from X-ray crystallographic data. Folding mechanisms are tentatively deduced from the observation of invariants in the architecture of folded proteins. The next chapters focus on the energetics of protein conformation and structure, indicating the principles of thermodynamic stability of the native structure, along with theoretical computation studies of protein folding, structure prediction, and folding simulation. The reader is also introduced to various experimental approaches; the reversibility of the unfolding-folding process; equilibrium and kinetic studies; and detection and characterization of intermediates in protein folding. This text concludes with a chapter dealing with problems specific to oligomeric proteins. This book is intended for research scientists, specialists, biochemists, and students of biochemistry and biology.
Download or read book Water in Biomechanical and Related Systems written by Adam Gadomski and published by Springer Nature. This book was released on 2021-04-21 with total page 332 pages. Available in PDF, EPUB and Kindle. Book excerpt: The contributed volume puts emphasis on a superior role of water in (bio)systems exposed to a mechanical stimulus. It is well known that water plays an extraordinary role in our life. It feeds mammalian or other organism after distributing over its whole volume to support certain physiological and locomotive (friction-adhesion) processes to mention but two of them, both of extreme relevance. Water content, not only in the mammalian organism but also in other biosystems such as whether those of soil which is equipped with microbiome or the ones pertinent to plants, having their own natural network of water vessels, is always subjected to a force field.The decisive force field applied to the biosystems makes them biomechanically agitated irrespective of whether they are subjected to external or internal force-field conditions. It ought to be noted that the decisive mechanical factor shows up in a close relation with the space-and-time scale in which it is causing certain specific phenomena to occur.The scale problem, emphasizing the range of action of gravitational force, thus the millimeter or bigger force vs. distance scale, is supposed to enter the so-called macroscale approach to water transportation through soil or plants’ roots system. It is merely related to a percolation problem, which assumes to properly inspect the random network architecture assigned to the biosystems invoked. The capillarity conditions turn out to be of prior importance, and the porous-medium effect has to be treated, and solved in a fairly approximate way.The deeper the scale is penetrated by a force-exerting and hydrated agent the more non-gravitational force fields manifest. This can be envisaged in terms of the corresponding thermodynamic (non-Newtonian) forces, and the phenomena of interest are mostly attributed to suitable changes of the osmotic pressure. In low Reynolds number conditions, thus in the (sub)micrometer distance-scale zone, they are related with the corresponding viscosity changes of the aqueous, e.g. cytoplasmatic solutions, of semi-diluted and concentrated (but also electrolytic) characteristics. For example, they can be observed in articulating systems of mammals, in their skin, and to some extent, in other living beings, such as lizards, geckos or even insects. Through their articulating devices an external mechanical stimulus is transmitted from macro- to nanoscale, wherein the corresponding osmotic-pressure conditions apply. The content of the proposed work can be distributed twofold. First, the biomechanical mammalian-type (or, similar) systems with extraordinary relevance of water for their functioning will be presented, also including a presentation of water itself as a key physicochemical system/medium. Second, the suitably chosen related systems, mainly of soil and plant addressing provenience, will be examined thoroughly. As a common denominator of all of them, it is proposed to look at their hydrophobic and/or (de)hydration effects, and how do they impact on their basic mechanical (and related, such as chemo-mechanical or piezoelectric, etc.) properties. An additional tacit assumption employed throughout the monograph concerns statistical scalability of the presented biosystems which is equivalent to take for granted a certain similarity between local and global system’s properties, mostly those of mechanical nature. The presented work’s chapters also focus on biodiversity and ecological aspects in the world of animals and plants, and the related systems. The chapters’ contents underscore the bioinspiration as the key landmark of the proposed monograph.

Download or read book Solvent Induced Interactions and Forces in Protein Folding written by Arieh Ben-Naim and published by Springer Nature. This book was released on 2023-06-12 with total page 185 pages. Available in PDF, EPUB and Kindle. Book excerpt: This monograph presents the molecular theory and necessary tools for the study of solvent-induced interactions and forces. After introducing the reader to the basic definitions of solvent-induced interactions, the author provides a brief analysis of the statistical thermodynamics. The book thoroughly overviews the connection of those interactions with thermodynamics and consequently focuses on specifically discussing the hydrophobic-hydrophilic interactions and forces. The importance of the implementation of hydrophilic interactions and forces in various biochemical processes is thoroughly analyzed, while evidence based on theory, experiments, and simulated calculations supporting that hydrophilic interactions and forces are far more important than the corresponding hydrophobic effects in many biochemical processes such as protein folding, self-assembly of proteins, molecular recognitions, are described in detail. This title is of great interest to students and researchers working in the fields of chemistry, physics, biochemistry, and molecular biology.
Download or read book Explicit solvent effects on protein physics written by Giovanni Salvi and published by Sudwestdeutscher Verlag Fur Hochschulschriften AG. This book was released on 2009 with total page 108 pages. Available in PDF, EPUB and Kindle. Book excerpt: Protein folding stands as one of the major interdisciplinary challenges of the last fifteen years, involving biology, chemistry, medicine and physics. In this book solvent effects, and the related hydrophobic effect, on proteins are investigated. Using a simple lattice model of proteins, in which the solvent is semi-explicitly taken into account, thermodynamical quantities can be investigated and the crucial role the solvent plays in protein folding can be demonstrated. Of particular relevance is our observation that a simple model, in which the potential energy is described in terms of the interactions between amino-acids only, does not correctly reproduce solvent effects. Approaches like this, in which solvent effects are treated implicitly, are commonly employed in many of more sophisticated models for protein folding dynamics. Our results are then of great importance as they suggest the treatment of the solvent in these models may need to be re-examined.
