Light Transducing Membranes by David Deamer Pdf

Light Transducing Membranes: Structure, Function, and Evolution covers the proceedings of a joint United States-Australia conference held in Honolulu, Hawaii on December 1977. Organized into four parts encompassing 19 chapters, the book focuses on structural, functional, and evolutionary aspects of light energy transduction by membranes. The first part of the book explores the problems of how membrane-related biomolecules could have evolved prior to the origin of life, how amphiphiles might have become organized in lipid bilayer structures, and what mechanisms may have been available for light energy transduction. The mechanisms by which ions, lipids, and proteins interact in membrane systems are described in the next part of the book. Some chapters in the third part of the book cover the analysis of several bacterial membranes as reconstituted, light transducing systems, providing a new tool for investigating basic mechanisms. Relevant aspects of mitochondrial energy transduction are also covered. Finally, the last part presents mechanism analysis by which intact bacteria and chloroplasts interact with light energy, which represent the end product of several billion of years of evolution. Biological evolutionists, biologists, researchers, teachers, and students who are interested in various aspects of light transducing membranes will greatly benefit from this book.

Energy Transduction in Biological Membranes by William A. Cramer,David B. Knaff Pdf

Energy Transduction in Biological Membranes was primarily designed for graduate courses in bioenergetics. Not only does it discuss basic principles and concepts central to modern membrane biochemistry, biophysics and molecular biology, but also (1) the components and pathways for electron transport and hydrogen ion translocation, and (2) the utilization of electrochemical ion gradients. The book is unique in presenting a comparative treatment of respiratory and photosynthetic energy transduction, and in using protein sequence data coupled with physical concepts to discuss the mechanisms of energy transducing proteins.

Membranes and Sensory Transduction by Giuliano Colombetti,Francesco Lenci Pdf

The main purpose of this book is to unify approaches and ideas in the field of aneural sensory transduction. This field has recently come to the attention of several research groups in various disciplines, and their number seems to be growing. Unfortunately, because of the diverse scientific backgrounds of the researchers in the field, the apparent heterogeneity of experimental techniques (i. e. , behavioral response analysis, sophisticated biochemical and genetic manipulations, conventional and pulsed laser spectroscopy) and theoretical approaches may be discouraging, for both the experienced worker and the new comer. Actually, this heterogeneity is more apparent than real, and unifying concepts, approaches, and ideas already exist, particularly with respect to all the questions concerning the role of membranes and their properties (such as ion permeability, electric potentials, and active transport) in the various steps of sensory perception and transduction processes. It is currently accepted that most, if not all, the fundamental facts in molecular sensory physiology of aneural organisms, be they chemosensory, photosensory, or geosensory, can ultimately be understood in terms of a few basic ideas. Each chapter of this book emphasizes and clarifies the role of mem brane properties and phenomena in the particular sensory response examined. Of course, in some cases, this task has been rather complex because of the limited amount of experimental data clearly supporting a membrane-based model of sensory transduction.

Neurotransmitter Release by Hugo J. Bellen Pdf

Understanding the mechanisms that underlie brain activity and function remains one of the major frontiers of biology. All the processes of how we co-ordinate our movements, sense our surroundings, react to stimuli and learn and retain information rely on complicated networks of neurons thatcommunicate with each other and their targets. This fast and accurate intercellular signalling most occurs at synapses, specialized processes of neurons that release chemical signals, called neurotransmitters. Neurotransmitters: Frontiers in Molecular Biology will provide the reader withextensive background information on neurotransmitter release. It takes a multidisciplinary approach, but does not assume previous knowledge having basic introductions to most topics. Topics however are covered in enough detail to be of interest to experts in the field. Throughout, emphasis is placedon the rationale by which proteins are assigned specific functions rather than just providing facts about function. The first chapter provides an introduction to the basic features and properties of the synapse and is followed by a chapter detailing several important techniques used to elucidatevarious aspects of release. Chapters 3 describes many of the biochemical approaches used to identify proteins involved in neurotransmitter release and then chapters 4 and 5 focus on more specific aspects of synaptic transmission: the proteins that transport neurotransmitters and the role ofphosphlipids in the process. The next five chapters concentrate on approaches to unravel the function of many proteins in vivo by using toxins, giant squid axons, C. elegans, Drosophila, and mice. The final chapter summarizes current knowledge on endocytosis and recycling. Knowledge of themolecular mechanisms underlying neurotransmitter release has expanded tremendously over the last 10 years. Many of the proteins involved have been isolated, but their roles have yet to be determined. These discoveries will be a major challenge and it is therefore the major aim of this book not onlyto provide information but also to generate excitement.

Membrane Biophysics: As Viewed from Experimental Bilayer Lipid Membranes by H.T. Tien †,A. Ottova-Leitmannova Pdf

This book summarizes the current status of research on bilayer lipid membranes (planar lipid bilayers and spherical liposomes). In addition to describing the properties of lipid bilayers and examining biomembrane phenomena, the book has two other objectives. The first is to present practical methods for the formation and study of lipid bilayers with either aqueous or metal-lipid bilayer interfaces. The second aim is to treat planar lipid bilayers as a new type of interfacial adsorption phenomena. The first nine chapters cover properties of biomembranes, basic principles of membrane biophysics, transport, electrochemistry, physiology, bioenergetics, and photobiology. Chapter 10 presents the following topics: lipid bilayers in medicine, supported lipid bilayers as sensors, a short discussion of liposomes, and solar energy transduction via semiconductor septum photovoltaic cells based on natural photosynthesis.

Light as an Energy Source and Information Carrier in Plant Physiology by Robert C. Jennings,Guiseppe Zucchelli,Francesco Ghetti,Giuliano Colombetti Pdf

A NATO Advanced Study Institute on "Light as Energy Source and Information Carrier in Plant Photo physiology" was held at Volterra, Italy, from September 26 to October 6, 1994, in order to consider the fundamental role that light plays in plant growth and development. This book summarises the main lectures given at this meeting which concentrated on both photochemical energy conversion and signalling (photosensing) aspects. Light harvesting and conversion into chemical energy in photosynthesis occurs at the level of chlorophyll/carotenoid containing photosystems in plants. Pigments are non covalently bound to a variety of polypeptides which serve as a specific scaffolding, necessary to determine the energy coupling between pigments and thus allowing rapid excitation energy trasfer from the antenna to the special reaction centre chlorophylls. Data from transient, time resolved spectroscopies, in the femtosecond and picosecond domain, together with model calculations, suggest that this process occurs in the 20-100 picosecond time span. The special ~ll u~ture of reaction centre complexes, ensures rapid primary charge separation, probably in the order of 1-3 picoseconds, with subsequent charge stabilisation reactions proceeding in the hundreds of picoseconds range. The recently resolved crystallographic structure of LHCII, the principal antenna complex of plants, allows precise determination of pigment-pigment distances and thus permits calculation of approximate chlorophyll-chlorophyll Forster hopping rates, which are in good agreement with time resolved measurements.

Receptors, Membrane Transport and Signal Transduction by A.E. Evangelopoulos,J.P. Changeux,L. Packer,T.G. Sotiroudis,K.W.A. Wirtz Pdf

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.
