Available in PDF, EPUB and Kindle. Book excerpt: Behind the neologism “ribozymes” lies a family of fascinating molecules, ribo-enzymes, which have been relatively little studied. These catalytically active RNAs are found in all strata of life, from viruses to the human genome. At the end of the 1970s, the discovery of a catalytic RNA nestled in an intron, followed by another involved in the maturation of transfer RNAs, led to the discovery of new ribozymes and the transition from a strictly “proteocentric” vision, inherited from the dogma of molecular biology, to a more “nucleocentric” one. Since then, a variety of ribozymes have been identified in genomes, where their functions often remain mysterious. Looking at Ribozymes traces the discovery of these molecules and presents a picture of their functional diversity, catalytic mechanisms and distribution within the tree of life.

Available in PDF, EPUB and Kindle. Book excerpt: Looking at Ribozymes: From Atomic to Molecular and Cellular Scales introduces ideas on how ribozymes "work" through a comparison of their common features and specificities. It covers how the (macro) molecular organization at different scales make it possible, what function they carry, where they are found, how they evolved, and how have they been used. The book emphasizes common and specific features of natural and artificial ribozymes, from the basics, to more advanced aspects, making it ideal for undergraduates, grad students and researchers. Specific sections cover different areas of research, from the atomic scale (catalysis), to the molecular (folding, dynamics). In addition, other sections cover macromolecular and cellular scales (dynamics, long-range interactions, self-assembly, cellular processes). The book is not a directory of ribozymes, it instead provides comparative knowledge, including the interdependent relationships between the different scales of description based on different experimental and theoretical approaches.

Download or read book Searching for Ribozymes with New and Improved Properties written by Edward Arthur Curtis and published by . This book was released on 2006 with total page 262 pages. Available in PDF, EPUB and Kindle. Book excerpt: (Cont.) Further analysis revealed two groups of mutations, derived from two different ribozymes used to build the shuffled pool, that each increased the rate of the ribozyme by approximately 30-fold. The effects of these mutations were independent of one another, and when combined produced a ribozyme with a rate 600-fold faster than that of the initial isolate. Together, these experiments provide insight into how RNA sequence space can be searched for ribozymes with new and improved properties.

Download or read book Therapeutic Applications of Ribozymes written by Kevin J. Scanlon and published by Humana. This book was released on 2013-08-08 with total page 462 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of Applications Therapeutic of Ribozymes is to provide an overview of the utility of ribozymes to selectively inhibit the expression of RNA. The ribozyme applications appearing in this book should benefit not only those experienced in ribozymes, but also those applying this ribozyme technology for the first time. It is hoped that a better understanding of the therapeutic application ofribozymes will have a significant impact on human disease in the near future. The field ofribozyme biochemistry has come a long way since the initial observation that RNA is capable of catalysis, initially in cis during processing of larger molecules and ultimately the use of ribozymes in trans to achieve cleavage of target sequence. The fundamental observation that hammerhead (and subsequently hairpin) ribozymes could be designed to cleave a target messenger RNA, and the clarification of sequence restrictions in both the ribozyme and the target RNA, have paved the ways for the use of ribozymes as a tool to manipulate gene expression at the molecular level. This had pre- ously been a domain of antisense oligonucleotides and triplex DNA. Sub- quent studies have explored the myriad biological systems in which ribozyme-mediated inhibition of genes involved in various cellular processes may be used to uncouple important signaling pathways or to reverse the p- notypic expression of a pathologic process.

Download or read book Ribozyme Protocols written by Philip C. Turner and published by Humana. This book was released on 2013-09-20 with total page 492 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of Ribozyme Protocols is to provide a helpful compilation of protocols that will be of use—^not only to those with some experience of ribozymes—^but also to those wishing to use ribozymes for the first time. Although it is usually impossible to cover every aspect of a scientific field, I believe this book approaches that ideal and should help all readers perform meaningful experiments using ribozymes. To design ribozymes, one must consider whether the target site will be accessible; this task can be facilitated by using computer programs that pre dict the folding of the target RNA. Such programs are detailed in Chapters 2 and 3. If the chosen target is an RNA virus that can mutate rapidly, it makes sense to consider those parts of the genome that are least likely to change during viral replication. An example of how this can be done is described in Chapter 4. Although computer analysis may be a useful starting point to select tar get sites, there seems, at the moment, to be no guarantee that any particular chosen site will be efficiently cleaved. Some workers have deliberately bypassed this problem by using libraries of ribozyme sequences and by select ing those that actually hybridize to and/or cleave the target; these methods are described in Chapters 5 and 6.
