Available in PDF, EPUB and Kindle. Book excerpt: The determination of the three-dimensional structure of a biological molecule is the starting point in the understanding of molecular mechanisms involved in its complex biochemical reactions. The molecular architecture of multimolecular systems such as membranes and chromosomes provides the key to the fascinating field of molecular biology. Stereochemical details of biological macromolecules and their interactions with pharmacological agents form the basis for drug design. Naturally, the study of the structure and function of biological molecules has aroused tremendous interest and investigations in this area are being carried out in a large number of laboratories. The techniques used for this purpose include both experimental methods (X-ray and neutron diffraction measurements, study of NMR, ESR, vibrational and electronic spectra, ORD, CD and dipole moment measurements, biochemical modifications etc. ) and the oretical methods (quantum mechanical and classical potential energy calculations, Monte Carlo simulations and molecular graphics). F or several years now, X-ray diffraction [1] has served as our only source of infor mation on the three-dimensional arrangements of atoms in biopolymers. Fiber-diffrac tion of DNA led to the proposal of the DNA double helix. Fibers of long~hain polymers show ordering in the direction of the fibre-axis but not in the transverse plane. Accurate estimates of the dimensions of helical structures can be made using techniques on the basis of which models of biopolymers can be constructed.

This book was released on 2012-05-17 with total page 129 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rasmus Brogaard's thesis digs into the fundamental issue of how the shape of a molecule relates to its photochemical reactivity. This relation is drastically different from that of ground-state chemistry, since lifetimes of excited states are often comparable to or even shorter than the time scales of conformational changes. Combining theoretical and experimental efforts in femto-second time-resolved photoionization Rasmus Brogaard finds that a requirement for an efficient photochemical reaction is the prearrangement of the constituents in a reactive conformation. Furthermore, he is able to show that by exploiting a strong ionic interaction between two chromophores, a coherent molecular motion can be induced and probed in real-time. This way of using bichromophoric interactions provides a promising strategy for future research on conformational dynamics.

Download or read book Protein Conformational Dynamics written by Ke-li Han and published by Springer Science & Business Media. This book was released on 2014-01-20 with total page 488 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book discusses how biological molecules exert their function and regulate biological processes, with a clear focus on how conformational dynamics of proteins are critical in this respect. In the last decade, the advancements in computational biology, nuclear magnetic resonance including paramagnetic relaxation enhancement, and fluorescence-based ensemble/single-molecule techniques have shown that biological molecules (proteins, DNAs and RNAs) fluctuate under equilibrium conditions. The conformational and energetic spaces that these fluctuations explore likely contain active conformations that are critical for their function. More interestingly, these fluctuations can respond actively to external cues, which introduces layers of tight regulation on the biological processes that they dictate. A growing number of studies have suggested that conformational dynamics of proteins govern their role in regulating biological functions, examples of this regulation can be found in signal transduction, molecular recognition, apoptosis, protein / ion / other molecules translocation and gene expression. On the experimental side, the technical advances have offered deep insights into the conformational motions of a number of proteins. These studies greatly enrich our knowledge of the interplay between structure and function. On the theoretical side, novel approaches and detailed computational simulations have provided powerful tools in the study of enzyme catalysis, protein / drug design, protein / ion / other molecule translocation and protein folding/aggregation, to name but a few. This work contains detailed information, not only on the conformational motions of biological systems, but also on the potential governing forces of conformational dynamics (transient interactions, chemical and physical origins, thermodynamic properties). New developments in computational simulations will greatly enhance our understanding of how these molecules function in various biological events.

Available in PDF, EPUB and Kindle. Book excerpt: Biomolecular Structure and Function covers the proceedings of the 1977 ?Cellular Function and Molecular Structure: Biophysical Approaches to Biological Problems? symposium. It summarizes the application of several biophysical techniques to molecular research in biology. This book starts by describing the use of deuterium-labeled lipids, as monitors of the degree of organization of membrane lipids. It also describes the use of carbon-13-labeled lipids, as indicators of molecular mobility. It explains the lipid-protein interactions involving two integral membrane proteins, mitochondrial cytochrome oxidase and calcium-dependent ATPase of muscle sarcoplasmic reticulum. The book goes on to present NMR studies on the organization and conformation of phospholipids, chloroplast membranes, and erythrocyte membranes. It also presents the ESR study of spectrin-phospholipid associations. It discusses the use of fluorescence probes, electrokinetics, neutron diffraction and ion theory studies of phospholipid-protein association, hormone disease, and senescence effects on prokaryotic and eukaryotic cells. Moreover, this book presents the experiments and phosphorus-31 NMR methodology to simultaneously monitor the intracellular pH and phosphate metabolism in a beating heart, functioning kidney, or an intact living microorganism. This book then describes physical probing of intracellular fluidity and structural changes attending tissue or cell cycles. It also relates relatively narrow lines in the hydrogen-1 NMR spectrum of the extremely viscous complex of the muscle protein troponin and highly polymerized tropomyosin. Structure-function studies of fibrous proteins, such as collagen, actin, and myosin, and active site analysis of enzymes are also presented. Finally, a wide variety of methodologies and technologies is exemplified. This includes proton, carbon, fluorine, phosphorus, and lithium NMR spectroscopy; spin labeling and EPR spectroscopy; chemical studies; light scattering and fluorescence; and electron microscopy.

Available in PDF, EPUB and Kindle. Book excerpt: The lock-and-key principle formulated by Emil Fischer as early as the end of the 19th century has still not lost any of its significance for the life sciences. The basic aspects of ligand-protein interaction may be summarized under the term 'molecular recognition' and concern the specificity as well as stability of ligand binding. Molecular recognition is thus a central topic in the development of active substances, since stability and specificity determine whether a substance can be used as a drug. Nowadays, computer-aided prediction and intelligent molecular design make a large contribution to the constant search for, e. g., improved enzyme inhibitors, and new concepts such as that of pharmacophores are being developed. An up-to-date presentation of an eternally young topic, this book is an indispensable information source for chemists, biochemists and pharmacologists dealing with the binding of ligands to proteins.
