Book Synopsis Protein Folding by : Charis Ghélis

Download or read book Protein Folding written by Charis Ghélis. This book was released on 1982. 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.

Book Synopsis The Protein Folding Problem and Tertiary Structure Prediction by : Kenneth M.Jr. Merz

Download or read book The Protein Folding Problem and Tertiary Structure Prediction written by Kenneth M.Jr. Merz. This book was released on 2012-12-06. Available in PDF, EPUB and Kindle. Book excerpt: A solution to the protein folding problem has eluded researchers for more than 30 years. The stakes are high. Such a solution will make 40,000 more tertiary structures available for immediate study by translating the DNA sequence information in the sequence databases into three-dimensional protein structures. This translation will be indispensable for the analy sis of results from the Human Genome Project, de novo protein design, and many other areas of biotechnological research. Finally, an in-depth study of the rules of protein folding should provide vital clues to the protein fold ing process. The search for these rules is therefore an important objective for theoretical molecular biology. Both experimental and theoretical ap proaches have been used in the search for a solution, with many promising results but no general solution. In recent years, there has been an exponen tial increase in the power of computers. This has triggered an incredible outburst of theoretical approaches to solving the protein folding problem ranging from molecular dynamics-based studies of proteins in solution to the actual prediction of protein structures from first principles. This volume attempts to present a concise overview of these advances. Adrian Roitberg and Ron Elber describe the locally enhanced sam pling/simulated annealing conformational search algorithm (Chapter 1), which is potentially useful for the rapid conformational search of larger molecular systems.

Book Synopsis Protein Folding and Misfolding by : Heinz Fabian

Download or read book Protein Folding and Misfolding written by Heinz Fabian. This book was released on 2011-09-18. Available in PDF, EPUB and Kindle. Book excerpt: Infrared spectroscopy is a new and innovative technology to study protein folding/misfolding events in the broad arsenal of techniques conventionally used in this field. The progress in understanding protein folding and misfolding is primarily due to the development of biophysical methods which permit to probe conformational changes with high kinetic and structural resolution. The most commonly used approaches rely on rapid mixing methods to initiate the folding event via a sudden change in solvent conditions. Traditionally, techniques such as fluorescence, circular dichroism or visible absorption are applied to probe the process. In contrast to these techniques, infrared spectroscopy came into play only very recently, and the progress made in this field up to date which now permits to probe folding events over the time scale from picoseconds to minutes has not yet been discussed in a book. The aim of this book is to provide an overview of the developments as seen by some of the main contributors to the field. The chapters are not intended to give exhaustive reviews of the literature but, instead to illustrate examples demonstrating the sort of information, which infrared techniques can provide and how this information can be extracted from the experimental data. By discussing the strengths and limitations of the infrared approaches for the investigation of folding and misfolding mechanisms this book helps the reader to evaluate whether a particular system is appropriate for studies by infrared spectroscopy and which specific advantages the techniques offer to solve specific problems.

Book Synopsis Protein Stability and Folding by : Wolfgang Pfeil

Download or read book Protein Stability and Folding written by Wolfgang Pfeil. This book was released on 2012-12-06. Available in PDF, EPUB and Kindle. Book excerpt: Protein folding remains one of the most exclusive problems of modern biochemistry. Structure analysis has given access to the wealth of the molecular architecture of pro teins. As architecture needs static calculations, protein structure is always related to thermodynamic factors that govern folding and stability of a particular folded protein over the non-organized polypeptide chain. During the past decades a huge amount of thermodynamic data related to protein folding and stability has been accumulated. The data are certainly of importance in dechiffring the protein folding problem. At the same time, the data can guide the con struction of modified and newly synthesized proteins with properties optimized for particular application. The intention of this book is a generation of a data collection which makes the vast amount of present data accessible for multidisciplinary research where chemistry, phy sics, biology, and medicine are involved and also pharmaceutical and food research and technology. It took several years to compile all the data and the author wishes to thank everyone who provided data, ideas or even unpublished results. The author is, in particular, indebted to Prof. Wadso (Lund, Sweden) and IUPAC's Steering Committee on Bio physical Chemistry. Furthermore, support by the Deutsche Forschungsgemeinschafi (INK 16 AI-I) is acknowledged.

Book Synopsis Protein Folding in Silico by : Irena Roterman-Konieczna

Download or read book Protein Folding in Silico written by Irena Roterman-Konieczna. This book was released on 2012-10-04. Available in PDF, EPUB and Kindle. Book excerpt: Protein folding is a process by which a protein structure assumes its functional shape of conformation, and has been the subject of research since the publication of the first software tool for protein structure prediction. Protein folding in silico approaches this issue by introducing an ab initio model that attempts to simulate as far as possible the folding process as it takes place in vivo, and attempts to construct a mechanistic model on the basis of the predictions made. The opening chapters discuss the early stage intermediate and late stage intermediate models, followed by a discussion of structural information that affects the interpretation of the folding process. The second half of the book covers a variety of topics including ligand binding site recognition, the "fuzzy oil drop" model and its use in simulation of the polypeptide chain, and misfolded proteins. The book ends with an overview of a number of other ab initio methods for protein structure predictions and some concluding remarks. Discusses a range of ab initio models for protein structure prediction Introduces a unique model based on experimental observations Describes various methods for the quantitative assessment of the presented models from the viewpoint of information theory
