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.

Proteins in living systems carry out a great variety of specific functions, each of which depends on the precise three-dimensional structure of a particular protein. Proteins are synthesized in the form of a flexible polypeptide chain that is capable of assuming a vast number of configurations; the transformation of this chain into a specific, relatively rigid three-dimensional structure is called folding--a remarkable process of self-organization. It is known that the amino acid sequences of some proteins have sufficient information to determine their three-dimensional structures. There are other proteins whose folding requires additional information beyond that found in the sequence of the mature protein. This book introduces the central problem of folding mechanisms as well as a number of other closely related issues. This book is neither a textbook nor a treatise. Rather, it is an attempt by several investigators to convey the excitement and challenges of those aspects of the folding problem in which they are actively engaged. The contributors give brief introductions to protein folding from the perspectives of molecular architecture, stability and dynamics, phage genetics, DNA exons, general physiology, and natural selection. They point out emerging new directions, including the suggestion of a class of diseases that result from protein folding defects.

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.

Protein Physics: A Course of Lectures covers the most general problems of protein structure, folding and function. It describes key experimental facts and introduces concepts and theories, dealing with fibrous, membrane, and water-soluble globular proteins, in both their native and denatured states. The book systematically summarizes and presents the results of several decades of worldwide fundamental research on protein physics, structure, and folding, describing many physical models that help readers make estimates and predictions of physical processes that occur in proteins. New to this revised edition is the inclusion of novel information on amyloid aggregation, natively disordered proteins, protein folding in vivo, protein motors, misfolding, chameleon proteins, advances in protein engineering & design, and advances in the modeling of protein folding. Further, the book provides problems with solutions, many new and updated references, and physical and mathematical appendices.

Free energy constitutes the most important thermodynamic quantity to understand how chemical species recognize each other, associate or react. Examples of problems in which knowledge of the underlying free energy behaviour is required, include conformational equilibria and molecular association, partitioning between immiscible liquids, receptor-drug interaction, protein-protein and protein-DNA association, and protein stability. This volume sets out to present a coherent and comprehensive account of the concepts that underlie different approaches devised for the determination of free energies. The reader will gain the necessary insight into the theoretical and computational foundations of the subject and will be presented with relevant applications from molecular-level modelling and simulations of chemical and biological systems. Both formally accurate and approximate methods are covered using both classical and quantum mechanical descriptions. A central theme of the book is that the wide variety of free energy calculation techniques available today can be understood as different implementations of a few basic principles. The book is aimed at a broad readership of graduate students and researchers having a background in chemistry, physics, engineering and physical biology.

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.

This book presents a new approach to the Protein Folding Problem. It starts with a clear description of what the protein folding problem involves. Then, it suggests non-conventional answers to some of the questions posed. In particular, it emphasizes the importance of hydrophilic interactions and hydrophilic forces, rather than the hydrophobic effects, for the stability of the native structure of proteins, as well for the speed of the folding process.
