Mechanisms of Protein Folding

Mechanisms of Protein Folding PDF Author: Roger H. Pain
Publisher: Oxford University Press, USA
ISBN: 9780199637881
Category : Science
Languages : en
Pages : 433

Book Description
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 Structure, Stability, and Folding

Protein Structure, Stability, and Folding PDF Author: Kenneth P. Murphy
Publisher: Springer Science & Business Media
ISBN: 1592591930
Category : Science
Languages : en
Pages : 258

Book Description
In Protein Structure, Stability, and Folding, Kenneth P. Murphy and a panel of internationally recognized investigators describe some of the newest experimental and theoretical methods for investigating these critical events and processes. Among the techniques discussed are the many methods for calculating many of protein stability and dynamics from knowledge of the structure, and for performing molecular dynamics simulations of protein unfolding. New experimental approaches presented include the use of co-solvents, novel applications of hydrogen exchange techniques, temperature-jump methods for looking at folding events, and new strategies for mutagenesis experiments. Unique in its powerful combination of theory and practice, Protein Structure, Stability, and Folding offers protein and biophysical chemists the means to gain a more comprehensive understanding of some of this complex area by detailing many of the major techniques in use today.

The Protein Folding Problem and Tertiary Structure Prediction

The Protein Folding Problem and Tertiary Structure Prediction PDF Author: Kenneth M.Jr. Merz
Publisher: Springer Science & Business Media
ISBN: 1468468316
Category : Science
Languages : en
Pages : 585

Book Description
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.
