Available in PDF, EPUB and Kindle. Book excerpt: Studies of chemical recognition in biology were initiated about half a century ago with the flrst kinetic data obtained on enzyme catalysis and inhibition. They led to a rather static representation of the recognition process illustrated by the lock and key model that still continues to influence our overall image of recognition and its specificity. In several cases, crystallographic studies of enzyme-substrate complexes have supported this model. Indeed, in a crystallized ligand-enzyme complex, a close fltting is observed between the active center of the enzyme and the functional groups of the ligand. How ever, this does not necessarily result from a direct recognition process between rigid structures, but may result from a progressive adaptation during which the initial struc tures of the enzyme and the ligand are modified (induced-flt mechanism). Recently, a great deal of work has been devoted to the study of recognition in more complex systems such as the replication or the translation machin~ries; clearly, the extraordinary precision of such systems cannot be explained solely in terms of physical matching between enzymes and their substrates. This has led to a noticeable change of perspective in these areas. As a result of the new kinetic viewpoint, one rather focuses on the time-course of the processes, on the kinetic balance between steps of the reaction, on the energy-accuracy relationships and on the strategies which permit the achievement of high precision using relatively error-prone components in an appropriate dynamic interplay.
Download or read book Principles of Molecular Recognition written by A.D. Buckingham and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 213 pages. Available in PDF, EPUB and Kindle. Book excerpt: The importance of molecular recognition in chemistry and biology is reflected in a recent upsurge in relevant research, promoted in particular by high-profile initiatives in this area in Europe, the USA and Japan. Although molecular recognition is necessarily microscopic in origin, its consequences are de facto macroscopic. Accordingly, a text that starts with intermolecular interactions between simple molecules and builds to a discussion of molecular recognition involving larger scale systems is timely. This book was planned with such a development in mind. The book begins with an elementary but rigorous account of the various types of forces between molecules. Chapter 2 is concerned with the hydrogen bond between pairs of simple molecules in the gas phase, with particular reference to the preferred relative orientation of the pair and the ease with which this can be distorted. This microscopic view continues in chapter 3 wherein the nature of interactions between solute molecules and solvents or between two or more solutes is examined from the experimental standpoint, with various types of spectroscopy providing the probe of the nature of the interactions. Molecular recognition is central to the catalysis of chemical reactions, especially when bonds are to be broken and formed under the severe con straint that a specific configuration is to result, as in the production of enan tiotopically pure compounds. This important topic is considered in chapter 4.

Download or read book Specific Interaction and Biological Recognition Processes written by Zeno Simon and published by CRC Press. This book was released on 1993-06-16 with total page 356 pages. Available in PDF, EPUB and Kindle. Book excerpt: Specific Interaction and Biological Recognition Processes is devoted to two major aspects of biological processes: specificity in biological recognition and the recognition processes themselves. Topics covered in specificity include the theoretical basis for specificity in biological recognition; the thermodynamic and chemical equilibrium background; and consideration of the relationship between size of combining sites and specificity. The use of semi-emperical potentials for calculating interaction energies and the potential of quantum chemistry methods for calculating receptor-effector affinities are also discussed. The various recognition processes described include DNA replication, transcription, translation, enzymatic reactions, transmembrane transport processes, mechanisms of action of hormones and other chemical messengers, and self-nonself recognition in immunology. Specific Interaction and Biological Recognition Processes will be a useful reference for molecular biologists, biochemists, enzymologists, immunologists oncologists, pharmaceutical researchers, and others interested in the topic.
Download or read book Basics of Molecular Recognition written by Dipankar Chatterji and published by CRC Press. This book was released on 2016-04-05 with total page 125 pages. Available in PDF, EPUB and Kindle. Book excerpt: Basics of Molecular Recognition explores fundamental recognition principles between monomers or macromolecules that lead to diverse biological functions. Based on the author’s longtime courses, the book helps readers understand the structural aspects of macromolecular recognition and stimulates further research on whether molecules similar to DNA or protein can be synthesized chemically. The book begins with the types of bonds that participate in the recognition and the functional groups that are capable of forming these bonds. It then explains how smaller molecules select their partners in the overall recognition scheme, offering examples of specific recognition patterns involving molecules other than nucleic acids. The core of the book focuses on macromolecular recognition—the central dogma of molecular biology. The author discusses various methods for studying molecular recognition. He also describes how molecules without biological functions can be arrayed or folded following certain rules and examines the nature of interactions among them. Molecular recognition is a vast area encompassing every aspect of biology. This book highlights all aspects of non-covalent macromolecular recognition processes, including DNA–protein recognition and sugar–protein recognition.
Download or read book Recent Trends in Molecular Recognition written by F. Diederich and published by Springer Science & Business Media. This book was released on 2013-04-17 with total page 274 pages. Available in PDF, EPUB and Kindle. Book excerpt: Reasoning in terms of molecular recognition may be traced back to Emil Fischer, who practiced the art of chemistry at Humboldt University in Prussian Berlin a century ago. Today, it is clearly recognized that molecular recognition impacts and determines all life processes. It has become a key research field in both chemistry and biology and the emerging interface of what now is being called "chemical biology". The technological advances derived from this knowledge are particularly important, diverse, and directly evident in the pharmaceutical industry. Under the auspices of the Ernst Schering Research Foundation, a workshop held in Berlin in February 1998 addressed novel basic developments of potential relevance to drug research efforts. A balance of timely research topics in molecular recognition is presented in the lectures delivered by a multidisciplinary international panel of renowned scholars and documented in this volume.
Download or read book Chemosensors of Ion and Molecule Recognition written by J.P. Desvergne and published by Springer Science & Business Media. This book was released on 1997-04-30 with total page 284 pages. Available in PDF, EPUB and Kindle. Book excerpt: The design and use of chemosensors for ion and molecule recognition - a branch of supramolecular chemistry - have developed at an extraordinary rate. This imaginative and creative area involves work at the interface of organic and inorganic chemistry, physical chemistry, biology, medicine and environmental science and is providing new sensors based on the specific signal delivered by the analyte-probe reaction. The emergence of efficient fluorescent receptors has allowed the detection, identification, and even titration of, for example, heavy metal or radionuclide pollutants. Further, with sensors displaying specific and strong complexation properties, such materials could be detected and removed at very low concentrations. Further, among other species of biological interest, sugars, oxygen and carbon dioxide can actually be probed with optodes and similar devices. This is clearly just the beginning of a very promising line of research. Audience: Organic chemists interested in creating new chemosensors, as well as the many potential end users of such sensors.

Download or read book Recognition Receptors in Biosensors written by Mohammed Zourob and published by Springer Science & Business Media. This book was released on 2010-01-08 with total page 864 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recognition receptors play a key role in the successful implementation of chemical and biosensors. Molecular recognition refers to non-covalent speci?c binding between molecules, one of which is typically a macromolecule or a molecular assembly, and the other is the target molecule (ligand or analyte). Biomolecular recognition is typically driven by many weak interactions such as hydrogen bo- ing, metal coordination, hydrophobic forces, van der Waals forces, pi-pi interactions and electrostatic interaction (due to permanent charges, dipoles, and quadrupoles) the polarization of charge distributions by the interaction partner leading to ind- tion and dispersion forces, and Pauli-exclusion-principle-derived inter-atomic repulsion, and a strong, “attractive” force arising largely from the entropy of the solvent and termed the hydrophobic effect. In recent years, there has been much progress in understanding the forces that drive the formation of such complexes, and how these forces are relate to the physical properties of the interacting molecules and their environment allows rational design of molecules and materials that interact in speci?c and desired ways. This book presents a signi?cant and up-to-date review of the various recognition elements, their immobilization, characterization techniques by a panel of dist- guished scientists. This work is a comprehensive approach to the recognition receptors area presenting a thorough knowledge of the subject and an effective integration of these receptors on sensor surfaces in order to appropriately convey the state-of the-art fundamentals and applications of the most innovative approaches.

This book was released on 1999-02-26 with total page 303 pages. Available in PDF, EPUB and Kindle. Book excerpt: The threat of domestic terrorism today looms larger than ever. Bombings at the World Trade Center and Oklahoma City's Federal Building, as well as nerve gas attacks in Japan, have made it tragically obvious that American civilians must be ready for terrorist attacks. What do we need to know to help emergency and medical personnel prepare for these attacks? Chemical and Biological Terrorism identifies the R&D efforts needed to implement recommendations in key areas: pre-incident intelligence, detection and identification of chemical and biological agents, protective clothing and equipment, early recognition that a population has been covertly exposed to a pathogen, mass casualty decontamination and triage, use of vaccines and pharmaceuticals, and the psychological effects of terror. Specific objectives for computer software development are also identified. The book addresses the differences between a biological and chemical attack, the distinct challenges to the military and civilian medical communities, and other broader issues. This book will be of critical interest to anyone involved in civilian preparedness for terrorist attack: planners, administrators, responders, medical professionals, public health and emergency personnel, and technology designers and engineers.
