Available in PDF, EPUB and Kindle. Book excerpt: The diversity of RNAs inside living cells is amazing. We have known of the more “classic” RNA species: mRNA, tRNA, rRNA, snRNA and snoRNA for some time now, but in a steady stream new types of molecules are being described as it is becoming clear that most of the genomic information of cells ends up in RNA. To deal with the enormous load of resulting RNA processing and degradation reactions, cells need adequate and efficient molecular machines. The RNA exosome is arising as a major facilitator to this effect. Structural and functional data gathered over the last decade have illustrated the biochemical importance of this multimeric complex and its many co-factors, revealing its enormous regulatory power. By gathering some of the most prominent researchers in the exosome field, it is the aim of this volume to introduce this fascinating protein complex as well as to give a timely and rich account of its many functions. The exosome was discovered more than a decade ago by Phil Mitchell and David Tollervey by its ability to trim the 3’end of yeast, S. cerevisiae, 5. 8S rRNA. In a historic account they laid out the events surrounding this identification and the subsequent birth of the research field. In the chapter by Kurt Januszyk and Christopher Lima the structural organization of eukaryotic exosomes and their evolutionary counterparts in bacteria and archaea are discussed in large part through presentation of structures.
Download or read book Biochemical Studies of the Eukaryotic RNA Exosome written by Matthew Alan Bratkowski and published by . This book was released on 2012 with total page 209 pages. Available in PDF, EPUB and Kindle. Book excerpt: The RNA exosome is a multi-subunit protein complex involved in RNA maturation, surveillance, and turnover of cellular RNA. It is composed of a nine subunit core that contains an RNA binding central channel and associates with the additional subunit Rrp44. Rrp44 contains a 3' to 5' processive exoribonuclease activity and an endoribonuclease activity in its N-terminal PIN domain. The exosome is present in both the nucleus and cytoplasm. In the nucleus, the exosome associates with a second nuclease, Rrp6, which is a distributive 3' to 5' exoribonuclease. Although a wealth of studies have helped to characterize the exosome, it is still not entirely clear how the exosome core functions in concert with these two nucleases to degrade RNA. In this dissertation, I present structural and biochemical studies of both the Rrp44 and Rrp6 bound exosome. In particular, I have attempted to crystallize a sub-complex of Rrp44 bound to the exosome, and present data that suggest that structured RNA can access Rrp44 without being first channeled through the exosome. Despite this conclusion, the exosome core still appears to down-regulate both the exonuclease and endonuclease activities of Rrp44, possibly by causing the protein to assume a conformation that prohibits it from promiscuous RNA degradation. Work on the Rrp6 containing exosme was conducted in attempts of obtaining an EM reconstruction of this complex. Crystallization of an RNA and Rrp6 binding exosome associated iii protein, Rrp47, was also attempted alone and in complex with Rrp6. Overall, the results that I present here will help to further characterize the function of the exosome in RNA mediated degradation. iv.

Download or read book Structural and Biochemical Characterisation of the Yeast Exosome Component Rrp40 written by Anna Oddone and published by . This book was released on 2007 with total page 131 pages. Available in PDF, EPUB and Kindle. Book excerpt: In eukaryotes, mRNA turnover, RNA quality control and 3'-end processing of several RNAs require the exosome, a multi-subunit protein complex that is conserved from yeast to human, and of which some archaeal counterparts have recently been described. The exosome core consists of six proteins homologous to bacterial RNase PH nucleases and of three S1-domain containing subunits, predicted to be involved in RNA substrate binding. Although the functional characterisation had considerably progressed since exosome first description, no structural information was available for the complex or its subunits, at the onset of this thesis. This thesis presents the first structure of a component of the eukaryotic exosome core, Rrp40 from Saccharomyces cerevisiae. The crystal structure of the N-terminal deletion construct of Rrp40 reveals that an S1 and an unusual KH domain are tightly packed against each other. The interface between the S1 and the KH domain is stabilised by a GxNG sequence, which is uniquely conserved in exosome KH domains. NMR data reveal the presence of a manganese-binding site at the interface of the two domains. Isothermal titration calorimetry shows that yeast Rrp40 and its archaeal counterpart Rrp4 have alone very low affinity for RNA, despite the fact that both S1 and KH domains are known nucleic acid-binding modules. The affinity of an archaeal core exosome for RNA, however, is significantly increased in the presence of Rrp4, indicating that multiple subunits may contribute to cooperative binding of RNA substrates by the exosome.

Available in PDF, EPUB and Kindle. Book excerpt: This book provides an in-depth overview on the manifold functions of fungal extracellular vesicles (EV) which span from cell-to-cell communication, pathogenicity and stimulation of host’s immunity to export of hundreds of biomolecules. The book summarizes the present knowledge on the impact of extracellular vesicles on fungal biology. Extracellular vesicles participate in fundamental biological processes in all living cells but only during the last 15 years the production and functions of EVs were identified and studied in fungal species too. Up to date more than 50 independent studies have shown that extracellular vesicles are produced by at least 20 fungal species. The book addresses researchers and advanced students in Microbiology, Mycology and Biotechnology.
