Available in PDF, EPUB and Kindle. Book excerpt: The aim of this study is to dissect molecular events that occur during the assembly of 30S subunit of the E. coli ribosome. The 30S ribosomal subunit is made up of 16S ribosomal RNA (rRNA) and 21 proteins (S1-S21). Crystal structure of the 30S subunit has answered longstanding questions on the three-dimensional organization of its constituents; however, this view does not expose the nature of interesting cooperative movements and conformational changes that occur during the formation of this macromolecular complex. Hence, biochemical and genetic efforts are required to understand these rearrangements. In this study, we have employed directed hydroxyl radical probing and used one of the ribosomal proteins (r-proteins) S15 as the probe to identify conformational changes that occur in 16S rRNA during different stages of assembly. S15 is one of the proteins that directly interact with the 16S rRNA and it governs the binding of four other proteins during 30S subunit formation. S15 has been converted into a probe by substituting cysteines at unique positions of the protein and attaching Fe(II) to the cysteines to form Fe(II) tethered S15 proteins (Fe(II)-S15). Hydroxyl radicals can be generated from these tethered sites by Fenton chemistry. The "directed hydroxyl radicals so produced cleave RNA elements that are in proximity to the tethered sites and these cleavage sites are mapped by primer extension. Using the recombinant in vitro reconstitution system and this directed hydroxyl radical probing approach, we have studied the folding of 16S rRNA proximal to S15 during the course of 30S subunit assembly. These studies have revealed protein-dependent conformational changes that occur in RNA environment of S15. Our work suggests that binding of r-proteins can result in changes that are quite remote from their primary binding site and that assembly of different domains can influence one another.

This book was released on 2012-09-20 with total page 325 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a premier resource on understanding the ribosome's essential nature and how it interacts with other proteins and nucleic acids to control protein synthesis. As one of the central foundations in our understanding of the biology at the molecular level, this topic appeals to a wide audience, from bench researcher to clinician. With the advent of atomic scale structures, methods to visualize and separate individual molecules, and the computational power to model the complex interactions of over a million atoms at once, our understanding of how gene expression is controlled at the level of protein translation is now deeply ensconced in the biophysical realm.

Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book RNA Structure and Function written by Robert W. Simons and published by . This book was released on 1998 with total page 764 pages. Available in PDF, EPUB and Kindle. Book excerpt: The striking functional versatility of RNA is attributable to its remarkable capacity for conformational change. Current models of RNA synthesis, its maturation, translation and degradation are all based on specific structures and there is growing appreciation of the functional importance of interactions between RNA and RNA-binding proteins. This work identifies the major intellectual and technical advances in understanding the part played by structure in how RNA works. It encompasses the experimental approaches used to define RNA structure and its influence on RNA functions such as transcription termination, catalysis, recoding and translational control. Investigators with these interests and students of molecular biology should find this volume a provocative survey of a rapidly-advancing field and a valuable complement to the monograph, The RNA World.

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.
