Download or read book The Alkali Metal Ions Their Role for Life written by Astrid Sigel and published by Springer. This book was released on 2016-02-09 with total page 628 pages. Available in PDF, EPUB and Kindle. Book excerpt: MILS-16 provides an up-to-date review of the impact of alkali metal ions on life. Their bioinorganic chemistry and analytical determination, the solid state structures of bio-ligand complexes and the properties of alkali metal ions in solution in the context of all kinds of biologically relevant ligands are covered, this includes proteins (enzymes) and nucleic acids (G-quadruplexes). Minerals containing sodium (Na+) and potassium (K+) are abundant in the Earth's crust, making Na+ and K+ easily available. In contrast, the alkali elements lithium (Li+), rubidium, and cesium are rare and the radioactive francium occurs only in traces. Since the intra- and extracellular, as well as the compartmental concentrations of Na+ and K+ differ significantly, homeostasis and active transport of these ions are important; this involves transporters/carriers and pore-forming ion channel proteins. Systems like Na+/K+-ATPases, H+/K+-ATPases or Na+/H+ antiporters are thoroughly discussed. The role of K+ in photosynthesis and the role of Na+ in charging the "battery of life" are pointed out. Also, the relationships between alkali metal ions and diseases (e.g., Parkinson or traumatic brain injury) are covered and the relevance of Li+ salts in medicine (pharmacology and mechanism) is reviewed. This and more is treated in an authoritative and timely manner in the 16 stimulating chapters of Volume 16, The Alkali Metal Ions: Their Role for Life, which are written by 44 internationally recognized experts from 12 nations. The impact of this vibrant research area is manifested in nearly 3000 references, over 30 tables and more than 150 illustrations (two thirds in color). MILS-16 also provides excellent information for teaching. Astrid Sigel, Helmut Sigel, and Roland K. O. Sigel have long-standing interests in Biological Inorganic Chemistry. Their research focuses on metal ion interactions with nucleotides and nucleic acids and on related topics. They edited previously 44 volumes in the series Metal Ions in Biological Systems.

Download or read book Functional Nucleic Acid Based Biosensors for Food Safety Detection written by Yunbo Luo and published by Springer. This book was released on 2018-07-13 with total page 353 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book highlights the development of a functional nucleic acid based biosensor detection method in the context of food safety. Although there have been major advances in food processing technology in both developed and developing countries, food safety assurance systems are generally becoming more stringent, in response to growing (both real and perceived) food safety problems. These problems are due in part to foodborne microorganisms, heavy metals, and small chemical molecules (biological toxins, pesticide residues, and veterinary drug residues), etc. In addition, the nucleic acid biomarkers (DNA methylation, microRNA, and circRNA) induced by these risk factors are also closely related to food safety. Accordingly, this book offers a brief guide to targets and strategies in functional nucleic acid based biosensors for food safety detection. Divided into several chapters that focus on various respective targets, it will be a valuable resource for students and researchers in the fields of biosensor detection, food science etc.
Download or read book Zinc Finger Proteins written by Shiro Iuchi and published by Springer Science & Business Media. This book was released on 2007-03-06 with total page 291 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the early 1980s, a few scientists started working on a Xenopus transcription factor, TFIIIA. They soon discovered a novel domain associated with zinc, and named this domain "zinc finger. " Th e number of proteins with similar zinc fingers grew quickly and these proteins are now called C2H2, Cys2His2 or classical zinc finger proteins. To date, about 24,000 C2H2 zinc finger proteins have been recognized. Approximately 700 human genes, or more than 2% of the genome, have been estimated to encode C2H2 finger proteins. From the beginning these proteins were thought to be numerous, but no one could have predicted such a huge number. Perhaps thousands of scientists are now working on C2H2 zinc finger proteins fi-om variou s viewpoints. This field is a good example of how a new science begins with the insight of a few scientists and how it develops by efforts of numerous independent scientists, in contrast to a policy-driven scientific project, such as the Human Genome Project, with goals clearly set at its inception and with work performed by a huge collaboration throughout the world. As more zinc finger proteins were discovered, several subfamilies, such as C2C2, CCHC, CCCH, LIM, RING, TAZ, and FYVE emerged, increasing our understanding of zinc fingers. The knowledge was overwhelming. Moreover, scientists began defining the term "zinc finger" differently and using various names for identical zinc fingers. These complications may explain why no single comprehensive resource of zinc finger proteins was available before this publication.

Download or read book Binding and Linkage written by Jeffries Wyman and published by University Science Books. This book was released on 1990 with total page 358 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ligand-macromolecule interactions are of fundamental importance in the control of biological processes. This book applies the principles of linkage thermodynamics to polyfunctional macromolecular systems under equilibrium conditions, and describes the binding, linkage, and feedback phenomena that lead to control of complex metabolic processes. The first chapter sets out the different processes (conformational changes, changes in state of aggregation, phase changes) involving biological macromolecules which are affected by chemical variables (such as ligands) or physical variables (such as temperature and pressure). The general effects of ligands on micromolecular conformations and interactions are illustrated with specific examples from the respiratory proteins, electron-transport proteins, and nucleic acid binding proteins. Subsequent chapters develop these themes, and describe in detail how the mathematics of regulation and control can be applied to macromolecules in biological system.

It is hoped that this information will contribute to the knowledge of nucleic acid component-metal ion interactions.
Download or read book Small Molecule DNA and RNA Binders written by Martine Demeunynck and published by John Wiley & Sons. This book was released on 2006-03-06 with total page 754 pages. Available in PDF, EPUB and Kindle. Book excerpt: The development of molecules that selectively bind to nucleic acids has provided many details about DNA and RNA recognition. The range of such substances, such as metal complexes, peptides, oligonucleotides and a wide array of synthetic organic compounds, is as manifold as the functions of nucleic acids. Nucleic acid recognition sequences are often found in the major or minor groove of a double strand, while other typical interactions include intercalation between base pairs or the formation of triple or quadruple helices. One example of a binding mode that has recently been proposed is end stacking on such complex structures as the telomere tetraplex. In this comprehensive book, internationally recognized experts describe in detail the important aspects of nucleic acid binding, and in so doing present impressive approaches to drug design. Since typical substances may be created naturally or synthetically, emphasis is placed on natural products, chemical synthesis, the use of combinatorial libraries, and structural characterization. The whole is rounded off by contributions on molecular modeling, as well as investigations into the way in which any given drug interacts with its nucleic acid recognition site.
