Leading practitioners detail revolutionary new spectrometric techniques for the identification and covalent structural characterization of macromolecules, proteins, glycoconjugates, and nucleic acids. Based on the Fourth International Symposium on Mass Spectrometry in the Health and Life Sciences held in San Francisco in 1998, this invaluable book contains tested strategies for solving many significant biomedical research problems. The techniques use mass spectrometry, automated computer processing of spectral information, and gene, protein, and EST databases for genomic and proteomic correlations. Mass Spectrometry in Biology and Medicine offers a unique opportunity to explore and apply these new techniques of mass spectrometry that are revolutionizing the identification and structural characterization of proteins, carbohydrates, and nucleic acids.

This volume describes chemical approaches to assess ion channel structure, function and pharmacology. Topics discussed include the use of engineered ionizable side chains to obtain information on permeation pathways and the local environment; the modification of engineered cysteine side chains, including cysteine scanning mutagenesis and the attachment of fluorescent probes and bio-reactive tethers; and the nascent use of genetic code expansion, evaluating its applications to ion channel and membrane proteins. This comprehensive text provides multifaceted perspectives on the great diversity of state-of-the-art methods which take advantage of the ever-expanding chemical toolbox to study ion channel biology. Capturing the contributions and innovations of renowned laboratory researchers in transmembrane protein study for the first time, this book is comprehensive in scope. It covers a wide array of experimental approaches: photochemistry, novel biological tools, and innovative spectroscopy, all combined with traditional techniques of electrophysiology and molecular biology. Novel Chemical Tools to Study Ion Channel Biology, part of the bestselling Advances in Experimental Medicine and Biology series is ideal for researchers and advanced students interested in biochemistry, biophysics, fluorometry, electrophysiology, and chemical biology. .

This book will provide latest insights in the functional potentials of ribonucleic acids in medine and the use of Spiegelmer and Spiegelzyme systems. It will also deal with a new type of delivery systems for cellular targeting.

This volume emphasizes the involvement of all facets of biology in the analysis of environmentally controlled movement responses. This includes biophysics, biochemistry, molecular biology and as an integral part of any approach to a closer understanding, physiology. The initial euphoria about molecular biology as the final solution for any problem has dwindled and the field agrees now that only the combined efforts of all facets of biology will at some day answer the question posed more than hundred years ago: "How can plants see?." One conclusion can be drawn from the current knowledge as summarized in this volume. The answer will most likely not be the same for all systems.

This book describes cutting-edge science and technology of the characterization, breeding, and development of yeasts and fungi used worldwide in fermentation industries such as alcohol beverage brewing, bread making, and bioethanol production. The book also covers numerous topics and important areas the previous literature has missed, ranging widely from molecular mechanisms to biotechnological applications related to stress response/tolerance of yeasts and fungi. During fermentation processes, cells of yeast and fungus, mostly Saccharomyces and Aspergillus oryzae spp., respectively, are exposed to a variety of fermentation "stresses". Such stresses lead to growth inhibition or cell death. Under severe stress conditions, their fermentation ability and enzyme productivity are rather limited. Therefore, in terms of industrial application, stress tolerance is the key characteristic for yeast and fungal cells. The first part of this book provides stress response/tolerance mechanisms of yeast used for the production of sake, beer, wine, bread, and bioethanol. The second part covers stress response/tolerance mechanisms of fungi during environmental changes and biological processes of industrial fermentation. Readers benefit nicely from the novel understandings and methodologies of these industrial microbes. The book is suitable for both academic scientists and graduate-level students specialized in applied microbiology and biochemistry and biotechnology and for industrial researchers and engineers who are involved in fermentation-based technologies. The fundamental studies described in this book can be applied to the breeding of useful microbes (yeasts, fungi), the production of valuable compounds (ethanol, CO2, amino acids, organic acids, and enzymes) and the development of promising processes to solve environmental issues (bioethanol, biorefinery).

This Volume features protocols for investigating the hydrocarbon- and lipid-specific activities of microbes. They include methods for studying chemotaxis, the colonisation of hydrocarbon surfaces, hydrocarbon uptake, respiration, nitrogen fixation, sulphate reduction, membrane stabilisation through cis-trans isomerisation of membrane fatty acids, and the production of biosurfactants and biopolymers in response to the presence of hydrocarbons. A protocol for studying the ability of microbes to control the concentration of hydrocarbons in their aqueous environment is also described, and phenotyping methods to reveal microbes' more general metabolic activities are presented. Several protocols for investigating acid production in connection with oil souring and biocorrosion by microbes in oil well, oil transportation and storage settings are presented. Lastly, protocols for measuring methanogenesis, as an example of microbial hydrocarbon production, are described.< Hydrocarbon and Lipid Microbiology ProtocolsThere are tens of thousands of structurally different hydrocarbons, hydrocarbon derivatives and lipids, and a wide array of these molecules are required for cells to function. The global hydrocarbon cycle, which is largely driven by microorganisms, has a major impact on our environment and climate. Microbes are responsible for cleaning up the environmental pollution caused by the exploitation of hydrocarbon reservoirs and will also be pivotal in reducing our reliance on fossil fuels by providing biofuels, plastics and industrial chemicals. Gaining an understanding of the relevant functions of the wide range of microbes that produce, consume and modify hydrocarbons and related compounds will be key to responding to these challenges. This comprehensive collection of current and emerging protocols will facilitate acquisition of this understanding and exploitation of useful activities of such microbes.

This book encompasses the exciting developments and challenges in the fast-moving and rapidly expanding research field of single-molecule kinetic analysis of cell signaling that promises to be one of the most significant and exciting areas of biological research for the foreseeable future. Cell signaling is carried out by complicated reaction networks of macromolecules, and single-molecule analyses has already demonstrated its power to unravel complex reaction dynamics in purified systems. To date, most of the published research in the field of single-molecule processes in cells, focus on the dynamic properties (translational movements of the centre of mass) of biological molecules. However, we hope that this book presents as many kinetic analyses of cell signaling as possible. Although single-molecule kinetic analysis of cellular systems is a relatively young field when compared with the analysis of single-molecule movements in cells, this type of analysis is highly important because it directly relates to the molecular functions that control cellular behavior and in the future, single-molecule kinetic analysis will be largely directed towards cellular systems. Thus, we hope that this book will be of interest to all those working in the fields of molecular and cell biology, as well as biophysics and biochemistry.

Spanning biological, mathematical, computational, and engineering sciences, computational biofluiddynamics addresses a diverse family of problems involving fluid flow inside and around living organisms, organs, tissue, biological cells, and other biological materials. Computational Hydrodynamics of Capsules and Biological Cells provides a comprehensive, rigorous, and current introduction to the fundamental concepts, mathematical formulation, alternative approaches, and predictions of this evolving field. In the first several chapters on boundary-element, boundary-integral, and immersed-boundary methods, the book covers the flow-induced deformation of idealized two-dimensional red blood cells in Stokes flow, capsules with spherical unstressed shapes based on direct and variational formulations, and cellular flow in domains with complex geometry. It also presents simulations of microscopic hemodynamics and hemorheology as well as results on the deformation of capsules and cells in dilute and dense suspensions. The book then describes a discrete membrane model where a surface network of viscoelastic links emulates the spectrin network of the cytoskeleton, before presenting a novel two-dimensional model of red and white blood cell motion. The final chapter discusses the numerical simulation of platelet motion near a wall representing injured tissue. This volume provides a roadmap to the current state of the art in computational cellular mechanics and biofluiddynamics. It also indicates areas for further work on mathematical formulation and numerical implementation and identifies physiological problems that need to be addressed in future research. MATLAB (R) code and other data are available at http://dehesa.freeshell.org/CC2

Theoretical chemistry has been an area of tremendous expansion and development over the past decade; from an approach where we were able to treat only a few atoms quantum mechanically or make fairly crude molecular dynamics simulations, into a discipline with an accuracy and predictive power that has rendered it an essential complementary tool to experiment in basically all areas of science.
This volume gives a flavour of the types of problems in biochemistry that theoretical calculations can solve at present, and illustrates the tremendous predictive power these approaches possess.
A wide range of computational approaches, from classical MD and Monte Carlo methods, via semi-empirical and DFT approaches on isolated model systems, to Car-Parinello QM-MD and novel hybrid QM/MM studies are covered. The systems investigated also cover a broad range; from membrane-bound proteins to various types of enzymatic reactions as well as inhibitor studies, cofactor properties, solvent effects, transcription and radiation damage to DNA.

The diverse applications in this volume range from the study of allosteric regulation of ion channel activity using a classic mutagenesis approach, to the study of channel subunit stoichiometry using a novel biophysical approach based on fluorescence resonance energy transfer. Highlights include methods for heterologous expression of ion channels in cells, for determining channel structure-function, and for studying channel regulation.

The environmental clean up industry has been estimated as having an annual turnover of $50 billion globally. With new regulations being written on addi tional chemicals that are just, now, becoming understood from a toxicological and environmental risk standpoint, this industry could expand even further. This is particularly true as more nations become industrialized. Typical conta minants that are of concern include agricultural byproducts, municipal wastes, industrial solvents, petroleum hydrocarbons, heavy metals, pesticides, radioac tive wastes, munitions, and other man made products. In order to treat and remediate these contaminants, practioners have several "tools" in the remediation "toolbox" including physical, chemical, and biological methods. One relatively new biological method that has been applied to address various environmental concerns is phytotechnologies. The method is defined as the use of vegetation to contain, sequester, remove, or degrade inorganic and organic contaminants in soils, sediments, surface waters, and groundwater. Although its roots were developed from other disciplines such as agronomy, agricultural engineering, chemical engineering, forestry, horticulture, hydroge ology, and microbiology, this set of technologies has grown substantially on its own in understanding of and application in the environmental clean up indus try around the world.

This thesis addresses two fundamental areas in contemporary organic chemistry: synthesis of natural products and catalytic asymmetric synthesis. Firstly, a new methodology, developed by our research group, which allows the asymmetric synthesis of lactones, a structural unit ubiquitous in natural products, was utilised in the synthesis of a number of natural product analogues that showed significant biological activity. Secondly, the development of a catalytic asymmetric synthesis of a key structural motif present in a number of natural products and pharmaceuticals was accomplished. During the course of this work we discovered dual stereo control, which is significant because it allows the configuration of a new stereo centre to be controlled by a simple change of proton source.

Medicinal chemistry is both science and art. The science of medicinal chemistry offers mankind one of its best hopes for improving the quality of life. The art of medicinal chemistry continues to challenge its practitioners with the need for both intuition and experience to discover new drugs. Hence sharing the experience of drug research is uniquely beneficial to the field of medicinal chemistry. Drug research requires interdisciplinary team-work at the interface between chemistry, biology and medicine. Therefore, the topic-related series Topics in Medicinal Chemistry covers all relevant aspects of drug research, e.g. pathobiochemistry of diseases, identification and validation of (emerging) drug targets, structural biology, drugability of targets, drug design approaches, chemogenomics, synthetic chemistry including combinatorial methods, bioorganic chemistry, natural compounds, high-throughput screening, pharmacological in vitro and in vivo investigations, drug-receptor interactions on the molecular level, structure-activity relationships, drug absorption, distribution, metabolism, elimination, toxicology and pharmacogenomics. In general, special volumes are edited by well known guest editors.

International concern in scientific, industrial, and governmental communities over traces of xenobiotics in foods and in both abiotic and biotic environments has justified the present triumvirate of specialized publications in this field: comprehensive reviews, rapidly published research papers and progress reports, and archival documentations. These three international publications are inte grated and scheduled to provide the coherency essential for nonduplicative and current progress in a field as dynamic and complex as environmental contamina tion and toxicology. This series is reserved exclusively for the diversified litera ture on ''toxic'' chemicals in our food, our feeds, our homes, recreational and working surroundings, our domestic animals, our wildlife and ourselves. Tre mendous efforts worldwide have been mobilized to evaluate the nature, pres ence, magnitude, fate, and toxicology of the chemicals loosed upon the earth. Among the sequelae of this broad new emphasis is an undeniable need for an articulated set of authoritative publications, where one can find the latest impor tant world literature produced by these emerging areas of science together with documentation of pertinent ancillary legislation. Research directors and legislative or administrative advisers do not have the time to scan the escalating number of technical publications that may contain articles important to current responsibility. Rather, these individuals need the background provided by detailed reviews and the assurance that the latest infor mation is made available to them, all with minimal literature searching."

Folding for the Synapse addresses the current view on how protein folding and misfolding, controlled by molecular chaperones, contribute to synapse function and dysfunction. Molecular chaperones have been studied in relation to de novo protein folding, but there is increasing awareness that chaperone function is required for the regulation of protein dynamics when functioning physiologically as an isolated moiety or part of a protein complex. This book will introduce both important concepts of folding machineries and give examples of the biological relevance of further chaperone functions.

It has become clear that tumors arise from excessive cell proliferation and a c- responding reduction in cell death. Tumors result from the successive accumulation of mutations in key regulatory target genes over time. During the 1980s, a number of oncogenes were characterized, whereas from the 1990s to the present, the emphasis shifted to tumor suppressor genes (TSGs). It has become clear that oncogenes and tumor suppressor genes function in the same pathways, providing positive and ne- tive growth regulatory activities. The signaling pathways controlled by these genes involve virtually every process in cell biology, including nuclear events, cell cycle, cell death, cytoskeletal, cell membrane, angiogenesis, and cell adhesion effects. Tumor suppressor genes are mutated in hereditary cancer syndromes, as well as somatically in nonhereditary cancers. In their normal state, TSGs control cancer development and p- gression, as well as contribute to the sensitivity of cancers to a variety of therapeutics. Understanding the classes of TSGs, the biochemical pathways they function in, and how they are regulated provides an essential lesson in cancer biology. We cannot hope to advance our current knowledge and to develop new and more effective therapies without understanding the relevant pathways and how they influence the present approaches to therapy. Moreover, it is important to be able to access the powerful tools now available to discover these genes, as well as their links to cell biology and growth control.

Biomass conversion research is a combination of basic science, applied science, and engineering testing and analysis. Conversion science includes the initial treatment (called pre-treatment) of the feedstock to render it more amenable to enzyme action, enzymatic saccharification, and finally product formation by microbiological or chemical processes. In Biomass Conversion: Methods and Protocols, expert researchers in the field detail methods which are now commonly used to study biomass conversion. These methods include Biomass Feedstocks and Cellulose, Plant Cell Wall Degrading Enzymes and Microorganisms, and Lignins and Hemicelluloses. Written in the highly successful Methods in Molecular Biology (TM) series format, the chapters include the kind of detailed description and implementation advice that is crucial for getting informed, reproducible results in the laboratory.

Humans face the challenge of producing enough food to meet the demands imposed by economic, biological and agricultural factors: rising population; rising income; and an expectation of higher quality food and a more diverse diet; decreasing amount of land available for food production; lowering environmental impact of agricultural practices and preserving biodiversity.
Biotechnology is one of the most exciting and dynamic industries of our day. It offers us the possibility of reducing our dependence on intensive farming. Plant biotechnology is central to the search for effective, environmentally safe and economically sound alternatives to the use of chemical pesticides and the exhaustion of natural resources. Today, applied plant science has four overall goals: increased crop yield, improved crop quality, reducing production costs and reducing negative environmental impact. Biotechnology is proving its value in meeting these goals. It offers farmers higher yielding crops with lower costs of production and new outlets such as nutraceuticals and crop-based bio-factories. It offers the European economy the potential of high quality, knowledge based job creation and the European consumer better quality, tastier and more nutritious food. Though there is public concern of genetic engineering, those who are close to the science understand that this is the next big frontier to be crossed. The potential and opportunities offered by plant biotechnology must not be missed. We must go forward on that basis rather than turning our backs on the science.
"Phytosfere'99" provides a comprehensive overview for plant biotechnology. It combines specific scientific articles, review articles and comments from outside people on it, which is unique in European Literature.

This updated edition describes advances that have occurred in our understanding of hormone action, metamorphosis, and reproduction, along with new sections on the role of microbiomes, insecticide action and its metabolism, and a chapter on genetics, genomics and epigenetic systems. The book represents a collaborative effort by two internationally known insect physiologists who have instructed graduate courses in insect physiology. As such, it is the ideal resource for entomologists and those in other fields who may require knowledge of insect systems.

As the title suggests, Isotope Effects in the Chemical, Geological and Bio Sciences deals with differences in the properties of isotopically substituted molecules, such as differences in the chemical and physical properties of water and the heavy waters. Since the various fields in which isotope effects are applied do not only share fundamental principles but also experimental techniques, this book includes a discussion of experimental apparatus and experimental techniques.

Isotope Effects in the Chemical, Geological and Bio Sciences is an educational monograph addressed to graduate students and others undertaking isotope effect research. The fundamental principles needed to understand isotope effects are presented in appropriate detail. While it is true that these principles are more familiar to students of physical chemistry and some background in physical chemistry is recommended, the text provides enough detail to make the book an asset to students in organic and biochemistry, and geochemistry.
