Download or read book Protein Crosslinking written by Mendel Friedman and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 765 pages. Available in PDF, EPUB and Kindle. Book excerpt: The word crosslinking implies durable combination of (usually large) distinct elements at specific places to create a new entity that has different properties as a result of the union. In the case of proteins, such crosslinking often results in important changes in chemical, functional, nutritional, and biomedical properties, besides physical properties simply related to molecular size and shape. (Nucleic acids, carbohydrates, and other biopolymers are correspondingly affected.) Since proteins are ubiquitous, the consequences of their crosslinking are widespread and often profound. Scientists from many disciplines including organic chemistry, bio chemistry, protein chemistry, food science, nutrition, radiation biology, pharmacology, physiology, medicine, and dentistry are, therefore, minutely interested in protein crosslinking reactions and their implications. Because protein crosslinking encompasses so many disciplines, in organizing the Symposium on Nutritional and Biochemical Conse quences of Protein Crosslinking sponsored by the Protein Subdivi sion of the Division of Agricultural and Food Chemistry of the American Chemical Society, I sought participants with the broadest possible range of interests, yet with a common concern for theore tical and practical aspects of protein crosslinking. An important function of a symposium is to catalyze progress by bringing together ideas and experiences needed for interaction among different, yet related disciplines. To my pleasant surprise, nearly everyone invited came to San Francisco to participate.

Download or read book Quantitative Methods in Proteomics written by Katrin Marcus and published by Humana Press. This book was released on 2012-06-08 with total page 539 pages. Available in PDF, EPUB and Kindle. Book excerpt: Protein modifications and changes made to them, as well as the quantities of expressed proteins, can define the various functional stages of the cell. Accordingly, perturbations can lead to various diseases and disorders. As a result, it has become paramount to be able to detect and monitor post-translational modifications and to measure the abundance of proteins within the cell with extreme sensitivity. While protein identification is an almost routine requirement nowadays, reliable techniques for quantifying unmodified proteins (including those that escape detection under standard conditions, such as protein isoforms and membrane proteins) is not routine. Quantitative Methods in Proteomics gives a detailed survey of topics and methods on the principles underlying modern protein analysis, from statistical issues when planning proteomics experiments, to gel-based and mass spectrometry-based applications. The quantification of post-translational modifications is also addressed, followed by the “hot” topics of software and data analysis, as well as various overview chapters which provide a comprehensive overview of existing methods in quantitative proteomics. Written in the successful Methods in Molecular BiologyTM series format, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible protocols, and notes on troubleshooting and avoiding known pitfalls. Authoritative and easily accessible, Quantitative Methods in Proteomics serves as a comprehensive and competent overview of the important and still growing field of quantitative proteomics.

Download or read book DNA Protein Interactions written by G. Geoff Kneale and published by Springer Science & Business Media. This book was released on 2008-02-02 with total page 428 pages. Available in PDF, EPUB and Kindle. Book excerpt: The study of protein-nucleic acid interactions is currently one of the most rapidly growing areas of molecular biology. DNA binding proteins are at the very heart of the regulation and control of gene expression, replication, and recombination: Enzymes that recognize and either modify or cleave specific DNA sequences are equally important to the cell. Some of the techniques reported in this volume can be used to identify previously unknown DNA binding proteins from crude cell extracts. Virtually all are capable of giving direct information on the molecular basis of the interaction—the location of the DNA binding site; the strength and specificity of binding; the identities of individual groups on specific bases involved in binding; the specific amino acid residues of the protein that interact with the DNA; or the effects of protein binding on gross conformation and local structure of DNA. The recognition of DNA sequences by proteins is a complex phenomenon, involving specific hydrogen bonding contacts to the DNA bases ("direct readout") and/or interactions with the sugar-phos phate backbone ("indirect readout"). The latter interactions can also be highly specific because of sequence-dependent conformational changes in the DNA. In addition, intercalation of planar aromatic amino acid side-chains between the DNA bases can occur, most notably with single-stranded DNA binding proteins. Furthermore, when bound, many DNA binding proteins induce drastic structural changes in the DNA as an integral part of their function.

Download or read book Affinity Chromatography written by Pascal Bailon and published by Springer Science & Business Media. This book was released on 2008-02-04 with total page 233 pages. Available in PDF, EPUB and Kindle. Book excerpt: Affinity chromatography, with its exquisite specificity, is based upon molecular recognition. It is a powerful tool for the purification of biomolecules. In recent years, numerous new applications and modified techniques have been derived from gro- specific interactions and biological recognition principles. An up-to-date review of the past, current, and future applications of affinity chromatography has been presented in the introductory chapter by Meir Wilchek and Irwin Chaiken. Though many of these new applications and techniques are well documented in the literature, it is often difficult to find methods that are written with the intent of helping new practitioners of affinity chromatography. This volume on Affinity Chromatography: Methods and Protocols is intended for the novice, as well as for - perts in the field. The protocols are written by experts who have developed and/or successfully employed these methods in their laboratories. Each chapter describes a specific technique, and since the book is intended to help the beginner, each technique is described simply and clearly, making sure that all relevant steps are included, assuming no previous knowledge. Each chapter contains an introduction describing the principles involved, followed by a Materials and Methods section, which lays the groundwork for the reader to conduct experiments step-by-step, in an orderly fashion. The following Notes section, which describes many of the problems that can occur, makes suggestions for overcoming them, and provides alternate procedures. These are precisely the sort of important, practical details that never seem to appear in the published literature.

Download or read book RNA Protein Interaction Protocols written by Susan R. Haynes and published by Springer Science & Business Media. This book was released on 2008-02-03 with total page 485 pages. Available in PDF, EPUB and Kindle. Book excerpt: The molecular characterization of RNA and its interactions with proteins is an important and exciting area of current research. Organisms utilize a variety of RNA–protein interactions to regulate the expression of their genes. This is particularly true for eukaryotes, since newly synthesized messenger RNA must be extensively modified and transported to the cytoplasm before it can be used for protein synthesis. The realization that posttranscriptional processes are critical components of gene regulation has sparked an explosion of interest in both stable ribonucleoprotein (RNP) complexes and transient RNA–protein interactions. RNA is conformationally flexible and can adopt complex structures that provide diverse surfaces for interactions with proteins. The fact that short RNA molecules (aptamers; see Chapter 16) can be selected to bind many different types of molecules is evidence of the structural variability of RNA. RNA molecules are rarely entirely single- or double-stranded, but usually contain multiple short duplexes interrupted by single-stranded loops and bulges; in some RNAs, such as tRNAs, the short duplexes stack on each other. Further variability is generated by the presence of non-Watson-Crick base pairs, modified nucleotides, and more complex structures, such as pseudoknots and triple-strand interactions.

Download or read book The Biology of Nonspecific DNA Protein Interactions written by Arnold Revzin and published by CRC Press. This book was released on 1990-08-27 with total page 278 pages. Available in PDF, EPUB and Kindle. Book excerpt: This important publication addresses the interactions of proteins with nonspecific binding sites on DNA as they play critical roles in fundamental cellular processes such as transcription, DNA replication, and recombination. The book presents current reviews of the biochemistry of representative nonspecific DNA-protein systems, and of their physiological functions. It includes chapters on the techniques used to characterize the complexes, on their thermodynamic properties, and on the role of nonspecific binding as gene regulatory proteins search for specific target sites on the chromosome. Systems considered include the effects of nonspecific binding in regulation of the lactose operon of Escherichia coli, the T4 bacteriophage gene 32 protein, the E. coli single strand binding (SSB) protein and recA protein, eukaryotic SSB's and histone-DNA complexes. The book presents those proteins displaying multiple modes of DNA binding as participants in more than one cellular process. This monograph combines rigorous descriptions of new findings for these important systems with provocative interpretations of the biological significance of the results. It is of great value to researchers ranging from graduate students to senior scientists in the areas of biochemistry, microbiology and molecular/cell biology.

Download or read book Chromatin Protocols written by Peter B. Becker and published by Springer Science & Business Media. This book was released on 2008-02-03 with total page 525 pages. Available in PDF, EPUB and Kindle. Book excerpt: More than 40 years after the discovery of the nucleosome as the fun- mental unit of chromatin, the multifaceted problem of how variations in ch- matin structure affect the activity of the eukaryotic genome has not been solved. However, during the past few years research on chromatin structure and fu- tion has gained considerable momentum, and impressive progress has been made at the level of concept development as well as filling in crucial detail. The structure of the nucleosome has been visualized at unprecedented reso- tion. Powerful multisubunit enzymes have been identified that alter histone/ DNA interactions in ways that expose regulatory sequences to factors initi- ing and regulating such nuclear processes as transcription. Though the imp- tance of posttranslational modifications of histones, notably their acetylation, has long been known, the finding that a number of bona fide regulators increase transcription by acetylating nucleosomes has lent new support to the old idea that the process of gene regulation is intimately related to the nature of the chromatin environment. A wealth of nonhistone proteins contribute to a continuum of structures with distinct biochemical properties and varying degrees of DNA condensation. Perhaps the most important conclusion from a large number of studies is a fresh appreciation of the dynamic nature of chromatin structure, the built-in flexibility providing the basis for regulation.

Download or read book Methods in Protein Sequence Analysis written by K. Imahori and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 307 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Ninth International Conference on Methods in Protein Sequence Analysis was held for the first time in Asia from September 20 to September 24, 1992 in Otsu (a city near Kyoto), Japan. Approximately 400 delegates attended the meeting. Forty papers were presented orally and 147 poster presentations were discussed. Academic sessions were held from early in the morning until late in the evening. We are confident that the Conference was successful in providing up-to-date information about methods in protein sequence analysis to all participants. Moreover, with the knowledge and understanding of the present standard of various methods of analysis that are being used and will be used, we were able to clarify areas that need to be evaluated, to be improved and be explored further. Major topics in the Conference mostly covered areas in the methodology of protein sequence analysis, such as: micropreparation and microsequencing of proteins, mass spectrometry, post-translational modification, prediction and database analysis, and analysis of protein structures of special interests. The evolution of genetic engineering in molecular biology has greatly accelerated the accumulation of knowledge on the amino acid sequence of novel proteins regardless of whether they are expressed or not expressed in living organisms. In the early stage of accumulation of structural information, the amino acid sequence itself is worthy of notice.

Download or read book High Resolution Profiling of Protein RNA Interactions written by Mathias Munschauer and published by Springer. This book was released on 2015-03-14 with total page 140 pages. Available in PDF, EPUB and Kindle. Book excerpt: The work reported in this book represents an excellent example of how creative experimentation and technology development, complemented by computational data analysis, can yield important insights that further our understanding of biological entities from a systems perspective. The book describes how the study of a single RNA-binding protein and its interaction sites led to the development of the novel ‘protein occupancy profiling’ technology that for the first time captured the mRNA sequence space contacted by the ensemble of expressed RNA binders. Application of protein occupancy profiling to eukaryotic cells revealed that extensive sequence stretches in 3’ UTRs can be contacted by RBPs and that evolutionary conservation as well as negative selection act on protein-RNA contact sites, suggesting functional importance. Comparative analysis of the RBP-bound sequence space has the potential to unravel putative cis-acting RNA elements without a priori knowledge of the bound regulators. Here, Dr. Munschauer provides a comprehensive introduction to the field of post-transcriptional gene regulation, examines state-of-the-art technologies, and combines the conclusions from several journal articles into a coherent and logical story from the frontiers of systems-biology inspired life science. This thesis, submitted to the Department of Biology, Chemistry and Pharmacy at Freie Universität Berlin, was selected as outstanding work by the Berlin Institute for Medical Systems Biology at the Max-Delbrueck Center for Molecular Medicine, Germany.
