The basic principle of electron crystallography is to calculate a 3D density map by combining the amplitudes obtained from electron diffraction patterns with the experimental phases calculated from images of two-dimensional crystals of membrane or soluble proteins. This technology is very well developed and has produced a number of atomic models of membrane proteins in a lipid environment. Focused on comprehensive experimental protocols, Electron Crystallography of Soluble and Membrane Proteins: Methods and Protocols covers the entire range of techniques used in electron crystallography, including protein sample preparation, 2D crystallization, and screening in negative stain over electron cryo-microscopy (cryo-EM) and data processing, as well as modeling of conformational changes. Additional chapters provide perspective on past, present, and future challenges as well as complementary methods. Written for the popular Methods in Molecular Biology (TM) series, the work contains the kind of detailed descriptions and implementation advice necessary to ensure successful results. Comprehensive and cutting-edge, Electron Crystallography of Soluble and Membrane Proteins: Methods and Protocols serves laboratories new to the methods as well as state-of-the-art facilities pursuing this exciting area of protein science.
Microbial natural products have been an important traditional
source of valuable antibiotics and other drugs but interest in them
waned in the 1990s when big pharma decided that their discovery was
no longer cost-effective and concentrated instead on synthetic
chemistry as a source of novel compounds, often with disappointing
results. Moreover understanding the biosynthesis of complex natural
products was frustratingly difficult. With the development of
molecular genetic methods to isolate and manipulate the complex
microbial enzymes that make natural products, unexpected chemistry
has been revealed and interest in the compounds has again flowered.
This two-volume treatment of the subject will showcase the most
important chemical classes of complex natural products: the
peptides, made by the assembly of short chains of amino acid
subunits, and the polyketides, assembled from the joining of small
carboxylic acids such as acetate and malonate. In both classes,
variation in sub-unit structure, number and chemical modification
leads to an almost infinite variety of final structures, accounting
for the huge importance of the compounds in nature and medicine.

Computational methods, and in particular quantum chemistry, have taken the lead in our growing understanding of noncovalent forces, as well as in their categorization. This volume describes the current state of the art in terms of what we now know, and the current questions requiring answers in the future. Topics range from very strong (ionic) to very weak (CH-- ) interactions. In the intermediate regime, forces to be considered are H-bonds, particularly CH--O and OH--metal, halogen, chalcogen, pnicogen and tetrel bonds, aromatic stacking, dihydrogen bonds, and those involving radicals. Applications include drug development and predictions of crystal structure.
Advances in molecular biology and genome research in the form of molecular breeding and genetic engineering put forward innovative prospects for improving productivity of many pulses crops. Pathways have been discovered, which include regulatory elements that modulate stress responses (e.g., transcription factors and protein kinases) and functional genes, which guard the cells (e.g., enzymes for generating protective metabolites and proteins). In addition, numerous quantitative trait loci (QTLs) associated with elevated stress tolerance have been cloned, resulting in the detection of critical genes for stress tolerance. Together these networks can be used to enhance stress tolerance in pulses. This book summarizes recent advances in pulse research for increasing productivity, improving biotic and abiotic stress tolerance, and enhancing nutritional quality.
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.
This volume on iron-sulfur proteins includes chapters that describe the initial discovery of iron-sulfur proteins in the 1960s to elucidation of the roles of iron sulfur clusters as prosthetic groups of enzymes, such as the citric acid cycle enzyme, aconitase, and numerous other proteins, ranging from nitrogenase to DNA repair proteins. The capacity of iron sulfur clusters to accept and delocalize single electrons is explained by basic chemical principles, which illustrate why iron sulfur proteins are uniquely suitable for electron transport and other activities. Techniques used for detection and stabilization of iron-sulfur clusters, including EPR and Mossbauer spectroscopies, are discussed because they are important for characterizing unrecognized and elusive iron sulfur proteins. Recent insights into how nitrogenase works have arisen from multiple advances, described here, including studies of high-resolution crystal structures.

In this book, the molecular recognition of DNA using small molecules is discussed, with a study of the photochemistry of BrU-labeled DNA. The purposes of the study were to develop small molecules for regenerative medicine, to develop a method to detect the recognition site of small molecules, and to detect the most important biological phenomena using the photochemistry of BrU-labeled DNA. The study began with the design and development of small molecules that can induce pluripotency genes. To deal with the important issue of cell permeability of the original compound, a new analogue of the original with improved gene expression was designed and synthesized. Using the photochemistry of BrU-labeled DNA, crucial biological phenomena such as cooperativity between transcription factors were detected. For the first time, the cooperativity was examined by excess electron transfer assay. DNA was also studied very carefully in order to understand the mechanism of the double-strand break in the UVA micro-irradiation technique. The mechanism of the double strand remained untouched. Nevertheless, the double-strand break mechanism was clearly demonstrated by Hoechst dye, as shown in this book.

human health but to our wildlife and environment as well. The
holistic approach taken in this book ensures that the researchers
have ready access to the details no matter which aspect of the
effects of CWA's they might be concerned with.
This book argues that, to be healthy, human beings should love nature and stay in balance with it as much as possible. In other words: do not unbalance nature so that your own balance is not disturbed. The best and healthiest way for human beings to live is to find balance in life and nature. In this regard, the book discusses useful, nutritious, functional foods, nutraceuticals and antioxidants, and how natural molecules, which are provided by nature, can be the best medicine for human beings. At a molecular level, stress is defined by the presence of unbalanced free radicals in the body. Most diseases - especially type 2 diabetes, which accounts for the majority of diabetics - can be traced back to this problem. Our scientific evidence indicates that type 2 diabetes isn't just a disease resulting from sugar, but also from stress. The book seeks to promote a healthier lifestyle by considering the psychoemotional dimension of wellness. And finally, it contends that good sleep is at the root of health and happiness for humanity, and that unbalanced free radicals are expelled from the body during restful sleep. The authors hope that this book will be a helpful guide and source of peace for readers, especially given their need for inner calm during the COVID-19 pandemic, and that the suggestions provided will show them the way to a better life.

Human exposure to toxic substances that cause cancer, reproductive abnormalities, and other adverse health effects is a topic of increasing interest to scientists, journalists, workers, business executives, advocacy groups, and the public at large. Citizen concern has prompted the government to establish an elaborate regulatory system designed to protect people from chemical exposures. Harnessing Science examines the role of science in toxic chemical regulation at the U.S. Environmental Protection Agency. The book postulates that scientific knowledge and advice from experts outside of government is critical to the competence and credibility of regulations designed to protect public health. This unique volume takes a close look at the contributions of three specific organizations that were designed to improve regulatory science: the Chemical Industry Institute of Toxicology (CIIT), the Science Advisory Board of the EPA, and the Health Effects Institute. Early chapters trace the origins and histories of each of these three organizations. Then regulatory case studies of selected chemical substances (unleaded gasoline, perchloroethylene, formaldehyde, nitrates, and carbon monoxide) are used to assess the contributions of CIIT, SAB, and HEI. The final chapter makes specific recommendations designed to strengthen these organizations. Harnessing Science for Environmental Regulation is essential reading for anyone who is interested in how science influences regulatory decisions about human exposure to toxic chemicals. It will be of special interest to federal and state policy makers, practicing scientists, environmental advocates, risk assessors, corporate managers, and environmental journalists. |
