Download or read book Fuzziness written by Monika Fuxreiter and published by Springer Science & Business Media. This book was released on 2012-03-07 with total page 210 pages. Available in PDF, EPUB and Kindle. Book excerpt: Detailed characterization of fuzzy interactions will be of central importance for understanding the diverse biological functions of intrinsically disordered proteins in complex eukaryotic signaling networks. In this volume, Peter Tompa and Monika Fuxreiter have assembled a series of papers that address the issue of fuzziness in molecular interactions. These papers provide a broad overview of the phenomenon of fuzziness and provide compelling examples of the central role played by fuzzy interactions in regulation of cellular signaling processes and in viral infectivity. These contributions summarize the current state of knowledge in this new field and will undoubtedly stimulate future research that will further advance our understanding of fuzziness and its role in biomolecular interactions.
Download or read book Mechanisms of Protein Folding written by Roger H. Pain and published by Oxford University Press, USA. This book was released on 2000 with total page 433 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the publication of the first edition of mechanisms of protein folding in 1994, significant advances in both the technical and conceptual understanding of protein folding. This new edition has been brought up to date in content, context, and authorship and will make the subject accessibleto a wide range of scientists. The emphasis on experimental approaches has benn maintained from the first edition but this time within the explicit context of simulations and energy surfaces. There is an introductory chapter explaining the 'new' model of protein folding, which takes into account theheterogeneity of the starting state. Advances in interpreting observed kinetic data and the development of technology to observe fast folding reactions and characterize intermediate structures have accompanied this new view and are covered in detail. The term 'molten globule'is often usedincorrectly but here the significance of the term is carefully described at different satges of folding. The concept of the transition state, including the complementary approaches of molecular dynamics and protein engineering, is also discussed in detail. In vitro studies provide the molecularbasis for the thermodynamic and kinetic energy minimization of the in vivo processes of protein folding and two of the potentially rate determining reactions are disulphide bond formation and proline isomerization. It has also become increasingly apparent that chaperone proteins play a vital role inprotein folding and other reactions of proteins involoving major conformational change and the molecular details of these processes are discussed in detail in chapter 14. The final chapter describes the centreal importance of protein folding and unfolding reactions in disease and gives claerdefinition of the term 'misfolding'. Studying protein folding in vivo is full of problems and to show how these problems can be overcome in practice, three case studies of three very different types of protein have been included: the small globular protein apomyoglobin; the fibrous protein collagen;and the membrane protein haemagglutinin.
Download or read book The Physics of Protein Structure and Dynamics written by Reinhard Schweitzer-Stenner and published by Elsevier. This book was released on 2024-09-23 with total page 328 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Physics of Protein Structure and Dynamics looks at various aspects of protein structure and dynamics from a physico-chemical point of view. It goes into some depth regarding the description of non-covalent forces that determine the relative stability of folded and unfolded proteins. Anharmonic protein dynamics involving motions between different minima of a rugged Gibbs energy landscape is described in great detail. The book combines various aspects of the protein folding/unfolding processes with an overview of intrinsically disordered proteins, which have attracted considerable interest of the protein community over the last 25 years but are thus far underrepresented in classroom-oriented textbooks. The book looks at protein folding and intrinsically disordered proteins as heavily interrelated topics that need to be viewed together. Furthermore, it presents some basic physico-chemical aspects of protein/peptide self-assembly into nanoscale fibrils. Intrinsically disordered peptides and proteins play a major role particularly in aggregation and self-assembly processes that lead to various diseases (Alzheimer, Parkinson, Huntington, Mad-Cow). Therefore, the relevance of protein disorder for protein self-assembly deserves a closer look. Protein self-assembly cannot be separated from protein folding since it is frequently the product of misfolding. With regard to modern theories, the folding processes are linked to insights on protein dynamics and the discovered relationship between proteins and spin glasses. - The readers will benefit from being provided with an in-depth overview of the physical concepts that govern different aspects of protein folding, disorder and self-assembly. By emphasizing the relationship between these issues, the approach adds a holistic character to the book - The book is to a major extent mathematically based. Mathematics is part of the language of physicists and physical chemists which cannot be properly substituted by words - For instructors, the book will offer a unique source for her/his teaching of current protein physics issues - The way how the book will be constructed (multiple references to primary literature with DOI links, literature-based problem sets and topics for discussion) will facilitate a learning process suitable for research-oriented students - Problem solving frequently requires the writing of short computer programs, something that is underemphasized in chemistry and biochemistry education (with the exception of computationally trained students, of course)
Download or read book The Physics of Complex Systems New Advances and Perspectives written by F. Mallamace and published by IOS Press. This book was released on 2004-11-24 with total page 638 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is widely known that complex systems and complex materials comprise a major interdisciplinary scientific field that draws on mathematics, physics, chemistry, biology, and medicine as well as such social sciences as economics. The role of statistical physics in this new field has been expanding. Statistical physics has shown how phenomena and processes in different research areas that have long been assumed to be unrelated can have a common description. Through the application of statistical physics, methods developed for studying order phenomena in simple systems and processes have been generalized to more complex systems. The two conceptual pillars in this approach are scaling and universality. This volume focuses on recent advances and perspectives in the physics of complex systems and provides both an overview of the field and a more detailed examination of the new ideas and unsolved problems that are currently attracting the attention of researchers. This book should be a useful reference work for anyone interested in this area, whether beginning graduate student or advanced research professional. It provides up-to-date reviews on cutting-edge topics compiled by leading authorities and is designed to both broaden the reader’s competence within their own field and encourage the exploration of new problems in related fields.

Available in PDF, EPUB and Kindle. Book excerpt: Protein Actions: Principles and Modeling is aimed at graduates, advanced undergraduates, and any professional who seeks an introduction to the biological, chemical, and physical properties of proteins. Broadly accessible to biophysicists and biochemists, it will be particularly useful to student and professional structural biologists and molecular biophysicists, bioinformaticians and computational biologists, biological chemists (particularly drug designers) and molecular bioengineers. The book begins by introducing the basic principles of protein structure and function. Some readers will be familiar with aspects of this, but the authors build up a more quantitative approach than their competitors. Emphasizing concepts and theory rather than experimental techniques, the book shows how proteins can be analyzed using the disciplines of elementary statistical mechanics, energetics, and kinetics. These chapters illuminate how proteins attain biologically active states and the properties of those states. The book ends with a synopsis the roles of computational biology and bioinformatics in protein science.
Download or read book Biologically Inspired Physics written by L. Peliti and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 383 pages. Available in PDF, EPUB and Kindle. Book excerpt: The workshop "Biologically Inspired Physics" was organized, with the support of the NATO Scientific Affairs Division and the Directorate-General for Science, Research and Development of the Commission of the European Communities, in order to review some subjects of physics of condensed matter which are inspired by biological problems or deal with biological systems, but which address physical questions. The main topics discussed in the meeting were: 1. Macromolecules: In particular, proteins and nucleic acids. Special emphasis was placed on modelling protein folding, where analogies with disordered systems in con densed matter (glasses, spin glasses) were suggested. It is not clear at this point whether such analogies will help in solving the folding problem. Interesting problems in nucleic acids (in particular DNA) deal with the dynamics of semiflexible chains with torsion and the relationship between topology and local structure. They arise from such biological problems as DNA packing or supercoiling. 2. Membranes: This field has witnessed recent progress in the understanding of the statistical mechanics of fluctuating flexible sheets, such as lipid bilayers. It appears that one is close to understanding shape fluctuations in red blood cells on a molec ular basis. Open problems arise from phenomena such as budding or membrane fusion. Experiments on model systems, such as vesicle systems or artificial lipids, have great potential. Phenomena occurring inside the membrane (protein diffusion, ionic pumps) were only discussed briefly.
Download or read book Structural Insights Into Gene Expression And Protein Synthesis written by Thomas A Steitz and published by World Scientific. This book was released on 2020-08-18 with total page 640 pages. Available in PDF, EPUB and Kindle. Book excerpt: Several years ago, Thomas Steitz agreed to contribute a volume to the 'World Scientific Series in Structural Biology' that would deal with the contributions he and his coworkers have made to structural biology during his remarkable career. Sadly, Tom died in the fall of 2018 before he had had time to do more than produce an outline for this book, and a list of the reprints he wanted it to contain.Fortunately, Tom's colleagues and coworkers responded enthusiastically when they were informed later that fall that if they were willing to help out, a volume would be published to commemorate his career. It fell to Anders Liljas, Peggy Eatherton, Tom's longtime administrative assistant, and Peter Moore, a close colleague, to oversee their efforts. Thomas Steitz is best known for the work he and his coworkers did to elucidate the biochemical basis of gene expression. The structures of a large number of the macromolecules involved in transcription and translation emerged from his laboratory over the course of his career. This book includes reprints of the most important papers he had published, grouped according to the structures they relate to, and commentaries written by the scientists who collaborated with him to solve each of them. It thus summarizes the achievements of one of the most distinguished biochemists of the second half of the 20th century.

Download or read book Protein Folding written by Tony R. Obalinsky and published by Nova Publishers. This book was released on 2006 with total page 294 pages. Available in PDF, EPUB and Kindle. Book excerpt: Proteins are one of the most basic components of all living cells and therefore serve a vital purpose in the cells of animals, plants and bacteria. They are comprised of chains of amino acids, which are held together by ribosome. These chains have many different patterns, which are known as `folds.' These folds are complicated, and therefore susceptible to irregularities that are known to be the source of many diseases. Cystic fibrosis, mad cow disease, Alzheimer's disease, emphysema and others are all initiated by improper protein folds. It is clear that, improving our understanding of protein folding is a key to fighting these diseases. This book presents recently performed research from around the world on this important subject.
Download or read book Protein Folding written by Grace E. Orellana and published by American Chemical Society. This book was released on 2024-05-08 with total page 170 pages. Available in PDF, EPUB and Kindle. Book excerpt: Life as we know it would not exist if proteins did not fold into functional three-dimensional structures, where α-helices, loops, and β-sheets act together to form active sites that drive a myriad of biochemical reactions in the cell. The failure of this process is linked to the pathology of various diseases, such as neurodegenerative disorders like Alzheimer’s, genetic conditions (like cystic fibrosis), and cancer. It is no wonder that close to $2 billion in worldwide research funding has been devoted over the last five years (2019–2025) to helping scientists understand the molecular details of protein folding, how it can fail in ways that promote disease in humans, and clinical paths to treat or prevent diseases linked to protein misfolding. This primer is prerequisite reading to the literature on this important topic for readers new to the field. Chapter one provides exposure to the three-dimensional structure of proteins; readers will learn how to identify secondary structures, protein motifs, and domains involved in biological function. Chapter two introduces methodologies to determine the three-dimensional structure of proteins; readers will learn modern techniques to determine the secondary structure composition and the orientation of atoms in three-dimensional space. By providing exposure to how the physical environment (i.e., chemical denaturants, pH, pressure, and temperature) controls protein denaturation, readers will learn how such information can be used to study the biophysical characteristics of proteins through various probes and methodologies.

Download or read book Computational Methods for Protein Folding Volume 120 written by Richard A. Friesner and published by John Wiley & Sons. This book was released on 2004-04-07 with total page 544 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the first attempts to model proteins on a computer began almost thirty years ago, our understanding of protein structure and dynamics has dramatically increased. Spectroscopic measurement techniques continue to improve in resolution and sensitivity, allowing a wealth of information to be obtained with regard to the kinetics of protein folding and unfolding, and complementing the detailed structural picture of the folded state. Concurrently, algorithms, software, and computational hardware have progressed to the point where both structural and kinetic problems may be studied with a fair degree of realism. Despite these advances, many major challenges remain in understanding protein folding at both the conceptual and practical levels. Computational Methods for Protein Folding seeks to illuminate recent advances in computational modeling of protein folding in a way that will be useful to physicists, chemists, and chemical physicists. Covering a broad spectrum of computational methods and practices culled from a variety of research fields, the editors present a full range of models that, together, provide a thorough and current description of all aspects of protein folding. A valuable resource for both students and professionals in the field, the book will be of value both as a cutting-edge overview of existing information and as a catalyst for inspiring new studies. Computational Methods for Protein Folding is the 120th volume in the acclaimed series Advances in Chemical Physics, a compilation of scholarly works dedicated to the dissemination of contemporary advances in chemical physics, edited by Nobel Prize-winner Ilya Prigogine.
