Book Synopsis Peptide and Protein Interaction with Membrane Systems by : Sara Bobone
Download or read book Peptide and Protein Interaction with Membrane Systems written by Sara Bobone and published by Springer. This book was released on 2014-05-31 with total page 147 pages. Available in PDF, EPUB and Kindle. Book excerpt: In her thesis, Sara Bobone outlines spectroscopic studies of antimicrobial peptides (AMPs) which are promising lead compounds for drugs used to fight multidrug resistant bacteria. Bobone shows that AMPs interact with liposomes and she clarifies the structure of pores formed by one of these molecules. These results help us to understand how AMPs are selective for bacterial membranes and how their activity can be finely tuned by modifying their sequence. Findings which solve several conundrums debated in the literature for years. In addition, Bobone uses liposomes as nanotemplates for the photopolymerization of hydrogels - exploiting the self- assembly properties of phospholipids. Bobone was able to trap an enzyme using nanometeric particles, while still allowing its activity by the diffusion of substrates and products through the network of the polymer. The innovative nano devices described in this thesis could solve many of the hurdles still hampering the therapeutic application of protein-based drugs.
Book Synopsis Peptide Arrays on Membrane Supports by : Joachim Koch
Download or read book Peptide Arrays on Membrane Supports written by Joachim Koch and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 192 pages. Available in PDF, EPUB and Kindle. Book excerpt: Proteins interacting with diverse ligands - proteins, peptides or DNA - are the basic principles underlying many biological processes, such as antigen-antibody binding, signal transduction or receptor binding. The technique of oligopeptide synthesis on a cellulose membrane and the subsequent binding assays allow the investigation of protein interactions. A particular advantage of these peptide arrays (SPOT - technology) is the high number of oligopeptide probes that can be tested in parallel. Detailed protocols for peptide synthesis, and the analysis of protein-protein, protein-DNA interactions as well as epitope mapping are presented in this manual. It is ideally suited not only for basic research laboratories but also for diagnostic and therapeutic applications since many diseases are related to dysfunctions in protein recognition and binding.

Available in PDF, EPUB and Kindle. Book excerpt: Protein-protein interactions (PPI) are at the heart of the majority of cellular processes, and are frequently dysregulated or usurped in disease. Given this central role, the inhibition of PPIs has been of significant interest as a means of treating a wide variety of diseases. However, there are inherent challenges in developing molecules capable of disrupting the relatively featureless and large interfacial areas involved. Despite this, there have been a number of successes in this field in recent years using both traditional drug discovery approaches and innovative, interdisciplinary strategies using novel chemical scaffolds. This book comprehensively covers the various aspects of PPI inhibition, encompassing small molecules, peptidomimetics, cyclic peptides, stapled peptides and macrocycles. Illustrated throughout with successful case studies, this book provides a holistic, cutting-edge view of the subject area and is ideal for chemical biologists and medicinal chemists interested in developing PPI inhibitors.

Book Synopsis Free Energy Calculations by : Christophe Chipot
Download or read book Free Energy Calculations written by Christophe Chipot and published by Springer Science & Business Media. This book was released on 2007-01-08 with total page 528 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Book Synopsis Membrane Dynamics and Domains by : Peter J. Quinn
Download or read book Membrane Dynamics and Domains written by Peter J. Quinn and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 502 pages. Available in PDF, EPUB and Kindle. Book excerpt: The fluid-mosaic model of membrane structure formulated by Singer and Nicolson in the early 1970s has proven to be a durable concept in terms of the principles governing the organization of the constituent lipids and proteins. During the past 30 or so years a great deal of information has accumulated on the composition of various cell membranes and how this is related to the dif ferent functions that membranes perform. Nevertheless, the task of explaining particular functions at the molecular level has been hampered by lack of struc tural detail at the atomic level. The reason for this is primarily the difficulty of crystallizing membrane proteins which require strategies that differ from those used to crystallize soluble proteins. The unique exception is bacteriorhodopsin of the purple membrane of Halobacterium halobium which is interpolated into a membrane that is neither fluid nor in a mosaic configuration. To date only 50 or so membrane proteins have been characterised to atomic resolution by diffraction methods, in contrast to the vast data accumulated on soluble proteins. Another factor that has been difficult to explain is the reason why the lipid compliment of membranes is often extremely complex. Many hundreds of different molecular species of lipid can be identified in some membranes. Remarkably, the particular composition of each membrane appears to be main tained within relatively narrow limits and its identity distinguished from other morphologically-distinct membranes.

Book Synopsis Brain Lipids in Synaptic Function and Neurological Disease by : Jacques Fantini
Download or read book Brain Lipids in Synaptic Function and Neurological Disease written by Jacques Fantini and published by Academic Press. This book was released on 2015-05-12 with total page 398 pages. Available in PDF, EPUB and Kindle. Book excerpt: Lipids are the most abundant organic compounds found in the brain, accounting for up to 50% of its dry weight. The brain lipidome includes several thousands of distinct biochemical structures whose expression may greatly vary according to age, gender, brain region, cell type, as well as subcellular localization. In synaptic membranes, brain lipids specifically interact with neurotransmitter receptors and control their activity. Moreover, brain lipids play a key role in the generation and neurotoxicity of amyloidogenic proteins involved in the pathophysiology of neurological diseases. The aim of this book is to provide for the first time a comprehensive overview of brain lipid structures, and to explain the roles of these lipids in synaptic function, and in neurodegenerative diseases, including Alzheimer’s, Creutzfeldt-Jakob’s and Parkinson’s. To conclude the book, the authors present new ideas that can drive innovative therapeutic strategies based on the knowledge of the role of lipids in brain disorders. Written to provide a "hands-on" approach for readers Biochemical structures explained with molecular models, and molecular mechanisms explained with simple drawings Step-by-step guide to memorize and draw lipid structures Each chapter features a content summary, up-to-date references for additional study, and a key experiment with an explanation of the technique
Book Synopsis Cell Boundaries by : Stephen H White
Download or read book Cell Boundaries written by Stephen H White and published by Garland Science. This book was released on 2021-12-31 with total page 565 pages. Available in PDF, EPUB and Kindle. Book excerpt: The central themes of Cell Boundaries concern the structural and organizational principles underlying cell membranes, and how these principles enable function. By building a biological and biophysical foundation for understanding the organization of lipids in bilayers and the folding, assembly, stability, and function of membrane proteins, the book aims to broaden the knowledge of bioscience students to include the basic physics and physical chemistry that inform us about membranes. In doing so, it is hoped that physics students will find familiar territory that will lead them to an interest in biology. Our progress toward understanding membranes and membrane proteins depends strongly upon the concerted use of both biology and physics. It is important for students to know not only what we know, but how we have come to know it, so Cell Boundaries endeavours to bring out the history behind the central discoveries, especially in the early chapters, where the foundation is laid for later chapters. Science is far more interesting if, as students, we can appreciate and share in the adventures—and misadventures—of discovering new scientific knowledge. Cell Boundaries was written with advanced undergraduates and beginning graduate students in the biological and physical sciences in mind, though this textbook will likely have appeal to researchers and other academics as well. Highlights the history of important central discoveries Early chapters lay the foundation for later chapters to build on, so knowledge is amassed High-quality line diagrams illustrate key concepts and illuminate molecular mechanisms Box features and spreads expand on topics in main text, including histories of discoveries, special techniques, and applications

Book Synopsis Antimicrobial Peptides by : Katsumi Matsuzaki
Download or read book Antimicrobial Peptides written by Katsumi Matsuzaki and published by Springer. This book was released on 2019-04-12 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents an overview of antimicrobial peptides (AMPs), their mechanisms of antimicrobial action, other activities, and various problems that must still be overcome regarding their clinical application. Divided into four major parts, the book begins with a general overview of AMPs (Part I), and subsequently discusses the various mechanisms of antimicrobial action and methods for researching them (Part 2). It then addresses a range of activities other than antimicrobial action, such as cell penetration, antisepsis, anticancer, and immunomodulatory activities (Part 3), and explores the prospects of clinical application from various standpoints such as the selective toxicity, design, and discovery of AMPs (Part 4). A huge number of AMPs have been discovered in plants, insects, and vertebrates including humans, and constitute host defense systems against invading pathogenic microorganisms. Consequently, many attempts have been made to utilize AMPs as antibiotics. AMPs could help to solve the urgent problem of drug-resistant bacteria, and are also promising with regard to sepsis and cancer therapy. Gathering a wealth of information, this book will be a bible for all those seeking to develop antibiotics, anti-sepsis, or anticancer agents based on AMPs.
