Book excerpt: "The RNA-dependent RNA polymerase (RdRp) of viruses belonging to the Flaviviridae family, including the hepatitis C virus (HCV) and bovine viral diarrhea virus (BVDV) is critical for viral replication. The major goal of this PhD study was to biochemically characterize the role of the polymerase during initiation and elongation of RNA synthesis, utilizing the BVDV RdRp as a model system. We showed that the BVDV polymerase efficiently incorporates chain-terminating nucleoside analogues, which ultimately arrest RNA synthesis. The incorporated chain-terminators, however, can be removed from the primer terminus in the presence of pyrophosphate (PPi). These results suggest that the phosphorolytic excision of incorporated chain-terminators is a possible mechanism that can diminish the efficiency of this class of compounds against viral RdRps. The chain-terminators then served as valuable tools in subsequent experiments to analyze the functional role(s) of the RdRp-associated GTP-specific binding site (G-site) and the consequences of GTP binding during the initiation of RNA synthesis. The results provide biochemical evidence for the existence of a G-site in the BVDV enzyme, and suggest that GTP binding controls template positioning during de novo initiation. Finally, through the development of a novel ribonuclease-based footprinting assay, it was determined that catalytically active complexes contact the newly synthesized RNA during elongation of RNA synthesis with approximately 6-7 base pairs. The polymerase moves along the template according to the position where RNA synthesis is arrested. Taken together, this study provides novel insight into mechanisms involved during initiation and elongation of RNA replication of viruses belonging to the Flaviviridae family. The ability of RdRps to excise incorporated chain-terminators points to possible shortcomings of nucleoside analogue inhibitors that are under development as antiviral agents for the treatment of infection with HCV." --

Download or read book Molecular Diagnostic PCR Handbook written by Gerrit J. Viljoen and published by Springer Science & Business Media. This book was released on 2005-12-06 with total page 325 pages. Available in PDF, EPUB and Kindle. Book excerpt: PREFACE The Joint FAO/IAEA Division of Nuclear Techniques in Food and Agriculture is involved in agricultural research and development and assists Member States of FAO and IAEA in improving strategies to ensure food security through the use of nuclear techniques and related biotechnologies, where such techniques have a valuable and often unique role. In particular, molecular diagnostic methods have rapidly evolved in the past twenty years, since the advent of the Polymerase Chain Reaction (PCR). They are used in a wide range of agricultural areas such as, improving soil and water management; producing better crop varieties; diagnosing plant and animal diseases; controlling insect pests and improving food quality and safety. The uses of nucleic acid-directed methods have increased significantly in the past five years and have made important contributions to disease control country programmes for improving national and international trade. These developments include the more routine use of PCR as a diagnostic tool in veterinary diagnostic laboratories. However, there are many problems associated with the transfer and particularly, the application of this technology. These include lack of consideration of: the establishment of quality-assured procedures, the required set-up of the laboratory and the proper training of staff. This can lead to a situation where results are not assured. This book gives a comprehensive account of the practical aspects of PCR and strong consideration is given to ensure its optimal use in a laboratory environment. This includes the setting-up of a PCR laboratory; Good Laboratory Practice and standardised of PCR protocols.
