Available in PDF, EPUB and Kindle. Book excerpt: The Discovery of Ribonuclease P and Enzymatic Activity of Its RNA Subunit Sydney Brenner and Francis H. C. Crick had a specific project in mind when they offered Sidney Altman a position in their group in 1969 to conduct postdoctoral research at the Medical Research Council Laboratory of Molecular Biology (LMB) in Cambridge, England. At the time, an intense international competition was on- ing in as many as a dozen labs to determine the three-dimensional structure of tRNA. At the LMB, Aaron Klug was attacking the structure by crystallographic analysis with Brian F. C. Clark providing large amounts of purified phenylalanine tRNA. (Eventually, Aaron announced his empirically determined 3-D structure of yeast phenylalanine tRNA, a structure that is generally common to tRNAs, due in part to several conserved, novel three-way nucleotide interactions. ) Concurrently, Michael Levitt, a Ph. D. student of Francis, was visually scrutinizing the cloverleaf secondary structure of the 14 tRNA sequences known at the time. Levitt was searching for nucleotide covariation in different parts of the molecules that were conserved in the 14 sequences known at the time. He identified a possible covariation of an apparent Watson-Crick pairing type between the residues at position 15 from the 5’ end of the tRNA and residue 48. This association implied these parts of the tRNA, namely the D loop containing residue 15 and the 5’ end of the T stem-adjoining residue 48, folded on one another in a tertiary structure shared by different tRNAs.

Download or read book RNA Metabolism and Gene Expression in Archaea written by Béatrice Clouet-d'Orval and published by Springer. This book was released on 2017-10-28 with total page 276 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on the regulation of transcription and translation in Archaea and arising insights into the evolution of RNA processing pathways. From synthesis to degradation and the implications of gene expression, it presents the current state of knowledge on archaeal RNA biology in 13 chapters. Topics covered include the modification and maturation of RNAs, the function of small non-coding RNAs and the CRISPR-Cas defense system. While Archaea have long been considered exotic microbial extremophiles, they are now increasingly being recognized as important model microorganisms for the study of molecular mechanisms conserved across the three domains of life, and with regard to the relevance of similarities and differences to eukaryotes and bacteria. This unique book offers a valuable resource for all readers interested in the regulation of gene expression in Archaea and RNA metabolism in general.

Download or read book Plant Resistance to Viruses written by David Evered and published by John Wiley & Sons. This book was released on 2008-04-30 with total page 226 pages. Available in PDF, EPUB and Kindle. Book excerpt: Concern about the environmental consequences of the widespread use of pesticides has increased, and evidence of pesticide-resistant virus vectors have continued to emerge. This volume presents a timely survey of the mechanisms of plant resistance and examines current developments in breeding for resistance, with particular emphasis on advances in genetic engineering which allow for the incorporation of viral genetic material into plants. Discusses the mechanisms of innate resistance in strains of tobacco, tomato, and cowpea; various aspects of induced resistance, including the characterization and roles of the pathogenesis-related proteins; antiviral substances and their comparison with interferon; and cross-protection between plant virus strains. Also presents several papers which evaluate the status of genetic engineering as it relates to breeding resistant plants. Among these are discussions of the potential use of plant viruses as gene vectors, gene coding for viral coat protein, satellite RNA, and antisense RNA, and practical issues such as the durability of resistant crop plants in the field.

Download or read book Artificial Nucleases written by Marina A. Zenkova and published by Springer Science & Business Media. This book was released on 2004-01-07 with total page 330 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: A wide range of topics are covered, including articles on nucleic acid structure, through their interactions with proteins to the control of gene expression. A number of authors address the subject of RNA, including the difficult but important subject of its chemical synthesis, the complexities of its structures and the mechanisms of transcript splicing. The probing of DNA structure is reviewed in papers on the application of hydroxyl radical and 1,10 phenanthroline copper cleavages. A number of important DNA-protein interactions are discussed, including DNA polymerase, the tryptophan and deoR repressors, and the resolvase enzymes which cleave Holliday junctions in recombination.
