The development of agents capable of cleaving RNA and DNA has attracted considerable attention from researchers in the last few years, because of the immediate and very important applications they can find in the emerging fields of biotechnology and pharmacology. There are essentially two classes of these agents - nucleases that occur naturally inside cells and synthetically produced artificial nucleases. The first class includes protein enzyme nucle ases and catalytic RNA structured ribozymes that perform cleavage of the phosphodiester bonds in nucleic acids according to a hydrolytic pathway in the course of different biochemical processes in the cell. A different pathway is used by some antibiotics which cleave DNA via redox-based mechanisms resulting in oxidative damage of nucleotide units and breakage of the DNA backbone. The above molecules are indispensable tools for manipulating nucleic acids and processing RNA; DNA-cleaving antibiotics and cytotoxic ribonucleases have demonstrated utility as chemotherapeutic agents. The second class, artificial nucleases, are rationally designed to imitate the active centers of natural enzymes by simple structures possessing minimal sets of the most important characteristics that are essential for catalysis. A dif ferent approach, in vitro selection, was also used to create artificial RNA and DNA enzymes capable of cleaving RNA. Being less efficient and specific as compared to the natural enzymes, the primitive mimics are smaller and robust and can function in a broad range of conditions.

This book covers the emerging topic of DNA nanotechnology and DNA supramolecular chemistry in its broader sense. By taking DNA out of its biological role, this biomolecule has become a very versatile building block in materials chemistry, supramolecular chemistry and bio-nanotechnology. Many novel structures have been realized in the past decade, which are now being used to create molecular machines, drug delivery systems, diagnosis platforms or potential electronic devices. The book combines many aspects of DNA nanotechnology, including formation of functional structures based on covalent and non-covalent systems, DNA origami, DNA based switches, DNA machines, and alternative structures and templates. This broad coverage is very appealing since it combines both the synthesis of modified DNA as well as designer concepts to successfully plan and make DNA nanostructures. Contributing authors have provided first a general introduction for the non-specialist reader, followed by a more in-depth analysis and presentation of their topic. In this way the book is attractive and useful for both the non-specialist who would like to have an overview of the topic, as well as the specialist reader who requires more information and inspiration to foster their own research.

An authoritative study of a cornerstone of cutting-edge DNA technology Nucleases are a class of enzymes that catalyze the hydrolysis of nucleic acids (DNA, RNA) in all organisms, including humans. In addition to their important biological role, nucleases have recently emerged as useful tools in laboratory studies, and have led to the development of such fields as recombinant DNA technology, molecular cloning, and genomics. Nawin Mishra’s Nucleases, the first comprehensive treatment of the subject, introduces the properties and biological roles of nucleases to newcomers in the field and provides the basis of their possible application to critical aspects of science, commerce, and industry. Covering the structure and biochemical properties of nucleases, Mishra’s text further guides the reader to understand how these enzymes can be exploited to make new products for the diagnosis and treatment of disease. Molecular cloning, made possible by the evolving understanding and application of nucleases, may well lead to the identification and characterization of genes responsible for diseases and their possible alleviation by gene therapy and the development of designer drugs. Nucleases is a one-stop, authoritative resource for students of biology and researchers currently practicing in the field. Chapter topics include: Ribonucleases Restriction Endonucleases Topoisomerases Sugar Non-Specific Nucleases Molecules That Interact with Nucleases An ideal text and reference work for professionals and students in biochemistry, genetics, and molecular biology, Nucleases promises to be the field’s standard-bearer for years to come.

Sequence-specific DNA binding ligands, amongst which triple helix forming oligonucleotides are the most efficient as yet, represent promising tools in a number of fields. One of their most promising applications is as antiviral tools: they can specifically target a viral gene, even if it is integrated into the host genome, and be used to specifically inactivate the viral gene or even destroy the cells harboring this gene. However, from science fiction to science there remains a gap; and we are at the moment on the threshold of this fascinating field. Triple Helix Forming Oligonucleotides considers the different aspects of the design and improvement, current or future, of these molecules and their structural analysis, as well as their applications, with special emphasis on the attempts to obtain biological effects of these potentially important tools. What emerges is that the current state of the research is encouraging, and that these molecules are already useful in some biotechnology applications.

Active Oxygen in Biochemistry

The field of "Oxygen Activation" has attracted considerable interest recently, not only because it presents challenges in those fields of basic research that aim to understand the fundamental aspects of chemical and biological reactions that involve dioxygen, but also because of its wide range of practical implications in such diverse fields as medicine, synthesis of pharmaceuticals and other organic compounds, materials science, and atmospheric science. This is the second of two volumes that focus on the subject of oxygen activation, the first slanted toward chemistry and the second toward biological chemistry. We planned these volumes to be more general than many monographs of this sort, not as detailed summaries of the authors' own research but rather as general overviews of the field. Our choice of topics was strongly influenced by our syllabus for a course entitled "Oxygen Chemistry," which two of us have twice taught jointly at UCLA. Definition of important issues, horizons, and future prospects was an important goal, and, although totally comprehensive coverage was not possible, we believe that we have chosen a representative selection of research topics current to the field. We have targeted this work to a diverse audience ranging from professionals in fields from physics to medicine to beginning graduate students who are interested in rapidly acquiring the basics of this field.
