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.

Available in PDF, EPUB and Kindle. Book excerpt: RNase P catalyzes tRNA 5'-end maturation in all organisms and organelles. The enzyme is composed of a single RNA subunit plus a number of proteins that increases from bacteria (one protein) over archaea (at least four proteins) to eukarya (nine to ten proteins). Conserved base identities indicate that the RNase P RNA subunits (P RNAs) from all three kingsdoms of life stem from a common ancestor. Yet, only in bacteria the P RNA alone is substantially active in vitro without the protein, whereas archaeal and eukaryal P RNAs are more dependent on the contribution of their protein moieties and display only residual activity when these are absent. RNase P thus represents a natural model system for the switch from ribozyme to ribonucleoprotein enzyme, generally accepted to have occurred during natural evolution of the RNA world to the protein world. The RNA subunit of cyanelle RNase P from Cyanophora paradoxa contains essentially all structural elements of bacterial P RNAs, but has been reported to be catalytically inactive. In contrast to these previous observations, we were able to detect activity of this P RNA in the absence of protein cofactors. Furthermore, the C. paradoxa P RNA forms a functional holoenzyme with proteobacterial P proteins. Analysis of C- and S-domain swaps between cyanelle and Escherichia coli P RNA revealed that their domains have the capacity to cooperate, because the hybrid RNAs were functional. However, activities of the chimeras lagged behind the catalytic performance of the bacterial P RNA, suggesting that both the C- and S-domain of the cyanelle P RNA are weakly functional, thus limiting the activity of each type of chimera (EC or CE). In addition or alternatively, domain interaction and overall folding may be suboptimal in the chimeras, as it likely is in the wild-type cyanelle P RNA. Furthermore, the organellar ribozyme is unusual compared to the consensus of bacterial P RNAs: RNA-alone activity is low and structural alterations as small as.

Download or read book Molecular Biology of RNA written by David Elliott and published by Oxford University Press. This book was released on 2017-01-31 with total page 445 pages. Available in PDF, EPUB and Kindle. Book excerpt: RNA plays a central, and until recently, somewhat underestimated role in the genetics underlying all forms of life on earth. This versatile molecule not only plays a crucial part in the synthesis of proteins from a DNA template, but is also intrinsically involved in the regulation of gene expression, and can even act as a catalyst in the form of a ribozyme. This latter property has led to the hypothesis that RNA - rather than DNA - could have played an essential part in the origin of life itself. This landmark text provides a systematic overview of the exciting and rapidly moving field of RNA biology. Key pioneering experiments, which provided the underlying evidence for what we now know, are described throughout, while the relevance of the subject to human disease is highlighted via frequent boxes. For the second edition of Molecular Biology of RNA, more introductory material has been incorporated at the beginning of the text, to aid students studying the subject for the first time. Throughout the text, new material has been included - particularly in relation to RNA binding domains, non-coding RNAs, and the connection between RNA biology and epigenetics. Finally, a new closing chapter discusses how exciting new technologies are being used to explore current topical areas of research.

Available in PDF, EPUB and Kindle. Book excerpt: A comprehensive, authoritative look at an emergent area in post-genomic science, Evolutionary genomics is an up-and-coming, complex field that attempts to explain the biocomplexity of the living world. Evolutionary Genomics and Systems Biology is the first full-length book to blend established and emerging concepts in bioinformatics, evolution, genomics, and structural biology, with the integrative views of network and systems biology. Three key aspects of evolutionary genomics and systems biology are covered in clear detail: the study of genomic history, i.e., understanding organismal evolution at the genomic level; the study of macromolecular complements, which encompasses the evolution of the protein and RNA machinery that propels life; and the evolutionary and dynamic study of wiring diagrams—macromolecular components in interaction—in the context of genomic complements. The book also features: A solid, comprehensive treatment of phylogenomics, the evolution of genomes, and the evolution of biological networks, within the framework of systems biology A special section on RNA biology—translation, evolution of structure, and micro RNA and regulation of gene expression Chapters on the mapping of genotypes to phenotypes, the role of information in biology, protein architecture and biological function, chromosomal rearrangements, and biological networks and disease Contributions by leading authorities on each topic Evolutionary Genomics and Systems Biology is an ideal book for students and professionals in genomics, bioinformatics, evolution, structural biology, complexity, origins of life, systematic biology, and organismal diversity, as well as those individuals interested in aspects of biological sciences as they interface with chemistry, physics, and computer science and engineering.

Download or read book Regulating with RNA in Bacteria and Archaea written by Gisela Storz and published by John Wiley & Sons. This book was released on 2018-11-01 with total page 1065 pages. Available in PDF, EPUB and Kindle. Book excerpt: Revealing the many roles of RNA in regulating gene expression For decades after the discoveries of messenger RNA, transfer RNA, and ribosomal RNA, it was largely assumed that the role of RNA in the cell was limited to shuttling the genomic message, chaperoning amino acids, and toiling in the ribosomes. Eventually, hints that RNA molecules might have regulatory roles began to appear. With the advent of genomics and bioinformatics, it became evident that numerous other RNA forms exist and have specific functions, including small RNAs (sRNA), RNA thermometers, and riboswitches to regulate core metabolic pathways, bacterial pathogenesis, iron homeostasis, quorum sensing, and biofilm formation. All of these functions, and more, are presented in Regulating with RNA in Bacteria and Archaea, written by RNA biologists from around the globe. Divided into eight sections-RNases and Helicases, Cis-Acting RNAs, Cis Encoded Base Pairing RNAs, Trans-Encoded Base Pairing RNAs, Protein Titration and Scaffolding, General Considerations, Emerging Topics, and Resources-this book serves as an excellent resource for established RNA biologists and for the many scientists who are studying regulated cellular systems. It is no longer a fair assumption that gene expression regulation is the provenance of proteins only or that control is exerted primarily at the level of transcription. This book makes clear that regulatory RNAs are key partners along with proteins in controlling the complex interactions and pathways found within prokaryotes.
