Membrane Receptors, Dynamics, and Energetics

Membrane Receptors, Dynamics, and Energetics PDF Author: K. Wirtz
Publisher: Springer
ISBN: 9781468453379
Category : Science
Languages : en
Pages : 395

Book Description
A NATO Advanced Study Institute on "Membrane Receptors, Dynamics and Energetics" was held in order to consider recent developments in membrane receptor research. Presentations and discussions focussed on signal transduction mechanisms (e.g. 2 G-proteins, transducin, Ca +) and on the structure and func tion of some selected receptors (i.e. low density lipoprotein receptor, acetylcholine receptor, growth factor receptors, toxin receptors). These topics were put in the larger con text of current knowledge on the structure and function of membranes; connections between different fields of research were established by in-depth discussions of energy transduc tion and transport mechanisms. Specialized membrane systems were discussed including chloroplasts and chromaffin granules. Functional relationships with specific lipids (e.g. phospho inositides, lipid A) were major topics of discussion. This book presents the content of the major lectures and a selection of most relevant posters presented during the course of the Institute. This book is intended to make the proceedings of the Institute accessible to a larger audience and to offer a comprehensive account of those topics of re ceptor, membrane and bioenergetics research that were at the center of interest during our stay on the Island of Spetsai from August 17 to 30, 1986.

Free Energy Calculations

Free Energy Calculations PDF Author: Christophe Chipot
Publisher: Springer Science & Business Media
ISBN: 3540384472
Category : Language Arts & Disciplines
Languages : en
Pages : 528

Book Description
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.

Allosteric Modulation of G Protein-Coupled Receptors

Allosteric Modulation of G Protein-Coupled Receptors PDF Author: Robert Laprairie
Publisher: Academic Press
ISBN: 0128197722
Category : Business & Economics
Languages : en
Pages : 214

Book Description
Allosteric Modulation of G Protein-Coupled Receptors reviews fundamental information on G protein-coupled receptors (GPCRs) and allosteric modulation, presenting original research in the area and collectively providing a comprehensive description of key issues in GPCR allosteric modulation. The book provides background on core concepts of molecular pharmacology while also introducing the most important advances and studies in the area. It also discusses key methodologies. This is an essential book for researchers and advanced students engaged in pharmacology, toxicology and pharmaceutical sciences training and research. Many of the GPCR-targeted drugs released in the past decade have specifically worked via allosteric mechanisms. Unlike direct orthosteric-acting compounds that occupy a similar receptor site to that of endogenous ligands, allosteric modulators alter GPCR-dependent signaling at a site apart from the endogenous ligand. Recent methodological and analytical advances have greatly improved our ability to understand the signaling mechanisms of GPCRs. We now know that allostery is a common regulatory mechanism for all GPCRs and not – as we once believed – unique to a few receptor subfamilies. - Introduces background on core concepts of molecular pharmacology, including statistical analyses, non-linear regression, complex models and GPCR-dependent signal transduction as they relate to allosteric modulation - Discusses critical advances and landmark studies, including discoveries in the area of GPCR allosteric modulation, which are reviewed for their importance in positive and negative regulation, protein-protein interactions, and small molecule drug discovery - Includes key methodologies used to study allosteric modulation at the in silico, in vitro, and in vivo levels of drug discovery and characterization

Classical And Quantum Dynamics In Condensed Phase Simulations: Proceedings Of The International School Of Physics

Classical And Quantum Dynamics In Condensed Phase Simulations: Proceedings Of The International School Of Physics PDF Author: Bruce J Berne
Publisher: World Scientific
ISBN: 9814496057
Category : Science
Languages : en
Pages : 881

Book Description
The school held at Villa Marigola, Lerici, Italy, in July 1997 was very much an educational experiment aimed not just at teaching a new generation of students the latest developments in computer simulation methods and theory, but also at bringing together researchers from the condensed matter computer simulation community, the biophysical chemistry community and the quantum dynamics community to confront the shared problem: the development of methods to treat the dynamics of quantum condensed phase systems.This volume collects the lectures delivered there. Due to the focus of the school, the contributions divide along natural lines into two broad groups: (1) the most sophisticated forms of the art of computer simulation, including biased phase space sampling schemes, methods which address the multiplicity of time scales in condensed phase problems, and static equilibrium methods for treating quantum systems; (2) the contributions on quantum dynamics, including methods for mixing quantum and classical dynamics in condensed phase simulations and methods capable of treating all degrees of freedom quantum-mechanically.

Physics of Biological Membranes

Physics of Biological Membranes PDF Author: Patricia Bassereau
Publisher: Springer
ISBN: 3030006301
Category : Science
Languages : en
Pages : 616

Book Description
This book mainly focuses on key aspects of biomembranes that have emerged over the past 15 years. It covers static and dynamic descriptions, as well as modeling for membrane organization and shape at the local and global (at the cell level) scale. It also discusses several new developments in non-equilibrium aspects that have not yet been covered elsewhere. Biological membranes are the seat of interactions between cells and the rest of the world, and internally, they are at the core of complex dynamic reorganizations and chemical reactions. Despite the long tradition of membrane research in biophysics, the physics of cell membranes as well as of biomimetic or synthetic membranes is a rapidly developing field. Though successful books have already been published on this topic over the past decades, none include the most recent advances. Additionally, in this domain, the traditional distinction between biological and physical approaches tends to blur. This book gathers the most recent advances in this area, and will benefit biologists and physicists alike.

Book Description
A NATO Advanced study Institute on "Receptors, Membrane Trans port and Signal Transduction", was held on the Island of Spet sai, Greece, from August 16-27, 1988, in order to consider re cent developments in membrane receptor research, membrane trans port and signal transduction mechanisms. These topics were put in the larger context of current knowledge on the structure and function of membranes; connections between different fields of research were established by in-depth dis cussions of energy transduction and transport mechanisms. The general principles of regulation by signal transduction and protein phosphorylation/dephosphorylation were presented in the context of specific cellular processes. Discussions included al so the role of protein tyrosine kinases which are structurally related to oncogene products and, therefore, implicated in va rious aspects of cell development and transformation. This book presents the content of the major lectures and a se lection of the most relevant posters presented during the course of the Institute. The book is intended to make the proceedings of the Institute accessible to a larger audience and to offer a comprehensive account of those topics on receptors, membrane transport and signal transduction that were discussed extensive ly during the course of the Institute.

Structure and Dynamics of Membranes

Structure and Dynamics of Membranes PDF Author: R. Lipowsky
Publisher: Elsevier
ISBN: 0080541917
Category : Technology & Engineering
Languages : en
Pages : 537

Book Description
The first volume of the Handbook deals with the amazing world of biomembranes and lipid bilayers. Part A describes all aspects related to the morphology of these membranes, beginning with the complex architecture of biomembranes, continues with a description of the bizarre morphology of lipid bilayers and concludes with technological applications of these membranes. The first two chapters deal with biomembranes, providing an introduction to the membranes of eucaryotes and a description of the evolution of membranes. The following chapters are concerned with different aspects of lipids including the physical properties of model membranes composed of lipid-protein mixtures, lateralphase separation of lipids and proteins and measurement of lipid-protein bilayer diffusion. Other chapters deal with the flexibility of fluid bilayers, the closure of bilayers into vesicles which attain a large variety of different shapes, and applications of lipid vesicles and liposomes. Part B covers membrane adhesion, membrane fusion and the interaction of biomembranes withpolymer networks such as the cytoskeleton. The first two chapters of this part discuss the generic interactions of membranes from the conceptual point of view. The following two chapters summarize the experimental work on two different bilayer systems. The next chapter deals with the process ofcontact formation, focal bounding and macroscopic contacts between cells. The cytoskeleton within eucaryotic cells consists of a network of relatively stiff filaments of which three different types of filaments have been identified. As explained in the next chapter much has been recently learned aboutthe interaction of these filaments with the cell membrane. The final two chapters deal with membrane fusion.
