Book Description
This book contemplates the structure, dynamics and physics of virus particles: From the moment they come into existence by self-assembly from viral components produced in the infected cell, through their extracellular stage, until they recognise and infect a new host cell and cease to exist by losing their physical integrity to start a new infectious cycle. (Bio)physical techniques used to study the structure of virus particles and components, and some applications of structure-based studies of viruses are also contemplated. This book is aimed first at M.Sc. students, Ph.D. students and postdoctoral researchers with a university degree in biology, chemistry, physics or related scientific disciplines who share an interest or are actually working on viruses. We have aimed also at providing an updated account of many important concepts, techniques, studies and applications in structural and physical virology for established scientists working on viruses, irrespective of their physical, chemical or biological background and their field of expertise. We have not attempted to provide a collection of for-experts-only reviews focused mainly on the latest research in specific topics; we have not generally assumed that the reader knows all of the jargon and all but the most recent and advanced results in each topic dealt with in this book. In short, we have attempted to write a book basic enough to be useful to M.Sc and Ph.D. students, as well as advanced and current enough to be useful to senior scientists with an interest in Structural and/or Physical Virology.

Book Description
Viruses are absolutely and strictly dependent on target host cells for their replication. However, they have their own unique strategies at each replication step from the entry into cells, transcription, translation, assembly of viral genome/proteins, and up to the release of progeny virions from cells. We virologists have to understand these complex biological interactions between viruses and host cells. Importantly, extensive studies based on bio-structural technology have revealed in succession the detailed and bottom line mechanisms of viral replication processes otherwise impossible. We now know the highly dynamic nature of viral genome/proteins, and are impressed by their ingeniously organized functionality in hostile host environments. For characterization of viruses as a unique genetic entity and pathogenic agent, it has been critical to investigate thoroughly the individual viral components and host factors involved in the virus replication cycle. Because many viral and cellular factors essential for viral replication and pathogenicity have been newly discovered through the efforts of virologists, the necessity of contribution to the progress of virology by the structural biology is now greatly increasing. To fully understand precise mechanisms underlying the functional interaction of viral and host molecules, needless to say, it is crucially required to have their structural information. We need to know molecular details of the nucleic acids, proteins, and interacting molecules. The information indispensable for understanding certain biological phenomena may only be provided by high-resolution three-dimensional structures. Of note, a number of anti-viral drugs have been generated based on the structural information. The interacting interfaces between virus and host components, which are important for viral replication, can be potent targets for anti-viral drugs. Their structural characterization would lead to designing rigid anti-viral drugs and/or vaccines. In this Research Topic, we wish to summarize and review what the structural biology has accomplished so far to resolve the important virological issues. We also wish to describe the perspective of the structural biology for the future virology. Finally, the presentation of ongoing original works is greatly encouraged.

Book Description
Biosynthesis of cellular and viral DNA and RNA has been a major topic in molecular biology and biochemistry. The studies by Arthur Kornberg and his colleagues on the in-vitro synthesis of DNA have opened new avenues to understanding the processes controlling the duplication of the genetic information encoded in the DNA and RNA of bacterial and mammalian cells. Viral nucleic acids are replicated in infected cells (bacterial, plant, and animal) by virus coded enzymes with or without the involvement of proteins and enzymes coded by the host cells. The ability of the virus to replicate its genome within a relatively short period in the infected cell makes it an excellent biological tool for studying the molecular events in nucleic acid replication. Indeed, the identification of a number of virus-coded proteins that participate in the biosynthesis of X174 and SV40 DNA has led to the construction of in-vitro systems for the study of nucleic acid biosynthesis. Similarly, studies on the replication of other phage, animal and plant viruses have provided an insight into the nucleic acid sequences from which DNA synthesis is initiated, as well as the proteins and enzymes that regulate the catalyse biosynthetic processes. Investi gation of the molecular processes involved in the replication of cellular and mitochondrial genomes has gained momentum from the rapid developments in the analyses of viral nucleic acid biosynthesis.

Book Description
RNA viruses cause a variety of acute and chronic diseases in humans. In addition to encoding for viral proteins, the genomes of RNA viruses often harbor secondary and tertiary RNA structures that have been associated with functions essential for successful virus replication and propagation. While antiviral research has focused almost exclusively on targeting viral proteins, the importance of RNA structural elements in virus lifecycles suggest these motifs could be promising therapeutic targets. In this thesis, I will dissect the contributions and druggability of RNA structures and complexes in two distinct phases of the viral lifecycle: first, in the virus packaging and production of influenza A virus (IAV), a negative-strand segmented RNA virus responsible for severe, sometimes fatal respiratory disease with pandemic potential; and second, in the replication complex of hepatitis C virus (HCV), a positive-strand RNA virus associated with chronic liver disease and cancer. To characterize the role of RNA secondary structures in IAV virus packaging, I employed the chemical mapping technique, Selective 2′ Hydroxyl Acylation analyzed by Primer Extension (SHAPE), which uses experimental probing data to guide computational modeling of high resolution RNA structure. This method enabled me to determine the RNA secondary structure of the IAV 5′ packaging signal region of virus genome segment PB2, the structures of known mutations in PB2 that disrupt virus packaging, as well as the discovery and characterization of novel mutants. Cutting-edge multidimensional mapping methods, Mutate-and-Map and Mutate-Map-Rescue, built upon this technical base and provided structural validation through discovery of compensatory mutant partners, which later informed both the in vivo exploration of packaging-defective viruses, as well as the design of locked nucleic acids (LNAs) targeting this structure. In vitro and in vivo drug targeting by LNAs of this IAV packaging signal structure exhibited powerful prophylactic and therapeutic efficacy. Combined, this work points to the promise of RNA secondary structures as valid antiviral targets, and sheds new light on IAV genome packaging mechanisms. The second section of my thesis built upon previous research in the lab. SHAPE was again employed to map both the RNA secondary structure of the HCV 5′ internal ribosomal entry site (IRES) and the structural interaction between the virus's 5′ untranslated region (UTR) and the miR-122 complex found to mediate viral replication. As an extension of this investigation, we sought to better parse the interaction of the viral replication complex with the host membrane in real-time. To do so, we employed a supported lipid-bilayer (SLB) platform and coupled it with quartz crystal microbalance with dissipation (QCM-D) to reconstitute and explore how components of the HCV replicase complex affect viral RNA replication and in vitro RNA transcription. The core enzyme of this complex, the NS5B RNA-dependent RNA polymerase, is required for in vivo virus replication and is a prime drug target for current and future HCV antiviral therapies. The reconstitution of full length NS5B in a membranous environment capable of active polymerase function, however, had not been demonstrated. Here, the SLB/QCM-D platform made it possible to reconstruct an in silico biological mimic of the host membrane to quantitatively probe and observe interactions between the membrane, the HCV viral RNA template and its associated viral proteins in real time. Together, these provide strong proof-of-concept for use of this technique in further understanding of the molecular details of HCV genome replication and future drug screening applications.
