By virtue of their role as catalysts of the aminoacylation reaction, the aminoacyl-tRNA synthetases ensure that the first step of translation is performed quickly and accurately. In this volume of 36 separate chapters, the many facets of this ancient and ubiquitous family are reviewed, including their surprising structural diversity, enzymology, tRNA interaction properties, and curious alternative functions. These chapters illustrate the degree to which the aminoacyl-tRNA synthetases employ a variety of mechanisms to carry out both the standard functions related to the synthesis of aminoacylated tRNA for protein synthesis, as well as the surprising functions associated with amino acid biosynthesis, cytokine function, and even the processivity of DNA replication. Other chapters explore the regulation of their synthesis, their role in disease, and their prospects as targets for antibacterial therapeutics. This monograph will be a valuable resource for all scientists interested in the fundamentals of protein synthesis from both a basic research and clinical perspective, as well as the relation of translational components to the evolution of the genetic code.

Biology of Aminoacyl-tRNA Synthetases, Volume 48 in The Enzymes series, highlights new advances in the field, with this new volume presenting interesting chapters on A narrative about our work on the endless frontier of editing, The puzzling evolution of aminoacyl-tRNA synthetases, Structural basis of the tRNA recognition by aminoacyl-tRNA synthetases, Catalytic strategies of aminoacyl-tRNA synthetases, Trans-editing by aminoacyl-tRNA synthetase-like editing domains, Adaptive and maladaptive mistranslation arising from aminoacyl-tRNA synthetases, Non-canonical inputs and outputs of tRNA aminoacylation, Structure and function of multi-tRNA synthetase complexes, Mitochondrial aminoacyl-tRNA synthetases, Non-canonical functions of human cytoplasmic tyrosyl-, tryptophanyl- and other aminoacyl-tRNA synthetases, and much more. - Provides the authority and expertise of leading contributors from an international board of authors - Presents the latest release in The Enzymes series

Molecular Microbiology Laboratory is designed to teach molecular biology techniques to upper level undergraduates majoring in the life sciences. An extremely detailed lab preparation manual for teaching assistants accompanies the lab book and contains a general discussion of scientific writing and critical reading, as well as detailed instructions for preparation and peer review of lab reports. Each experimental unit is accompanied by a number of additional writing exercises based upon primary journal articles. The studies in these articles employ the techniques that the students are learning in the lab exercises, which reinforces their understanding of the material. These are techniques that students in any biological science will need to know, making this manual applicable to any life science curriculum.Key Features* Not a typical cookbook lab exercise, offers students the excitement and intellectual challenge of characterizing true unknowns. They could discover a new species! * Success rate greater than 85% for the entire experiment, even with very inexperienced students. * The ONLY manual that incorporates writing exercises into the curriculum. * Co-authored by Dr. Janine Trempy, one of four senior editors of the Journal of Microbiology Education, published by the American Society for Microbiology.

This highly illustrated book provides an up-to-date description of the structure and function of the translation system including ribosomes, tRNAs, translation factors, antibiotics and aminoacyl-tRNA synthetases.Research on translation is undergoing rapid changes and is receiving significant attention as evidenced by the Nobel Prize in Chemistry 2009. The structural research by crystallography and cryo-EM forms part of an interactive framework that involves biochemistry and molecular computation. The book provides a comprehensive overview of translation in light of the structural results. It is a valuable resource for scientists in this and related fields, as well as for students taking courses with a focus on translation.There is no other book in this field currently except the previous edition of this book. The authors have for a long time worked in the field of structure and function of the translation system.

This book is a printed edition of the Special Issue "The Origin and Evolution of the Genetic Code: 100th Anniversary Year of the Birth of Francis Crick" that was published in Life

Ribozymes Provides comprehensive coverage of a core field in the molecular biosciences, bringing together decades of knowledge from the world’s top professionals in the field Timely and unique in its breadth of content, this all-encompassing and authoritative reference on ribozymes documents the great diversity of nucleic acid-based catalysis. It integrates the knowledge gained over the past 35 years in the field and features contributions from virtually every leading expert on the subject. Ribozymes is organized into six major parts. It starts by describing general principles and strategies of nucleic acid catalysis. It then introduces naturally occurring ribozymes and includes the search for new catalytic motifs or novel genomic locations of known motifs. Next, it covers the development and design of engineered ribozymes, before moving on to DNAzymes as a close relative of ribozymes. The next part examines the use of ribozymes for medicinal and environmental diagnostics, as well as for therapeutic tools. It finishes with a look at the tools and methods in ribozyme research, including the techniques and assays for structural and functional characterization of nucleic acid catalysts. The first reference to tie together all aspects of the multi-faceted field of ribozymes Features more than 30 comprehensive chapters in two volumes Covers the chemical principles of RNA catalysis; naturally occurring ribozymes, engineered ribozymes; DNAzymes; ribozymes as tools in diagnostics and therapy, and tools and methods to study ribozymes Includes first-hand accounts of concepts, techniques, and applications by a team of top international experts from leading academic institutions Dedicates half of its content to methods and practical applications, ranging from bioanalytical tools to medical diagnostics to therapeutics Ribozymes is an unmatched resource for all biochemists, biotechnologists, molecular biologists, and bioengineers interested in the topic.
