Full textIn eukaryotic organisms, RNA polymerase III is responsible for synthesis of transfert RNAs, 5S ribosomal RNA and other small RNAs. Initiation of transcription involves a multistep assembly of transcription factors: TFIIIC binds first to intragenic promoter sequences, it then recruits TFIIIB which in turn recruits RNA polymerase III. TFIIIC is a six subunits factor organized in two large globular domains named tA and tB that respectively bind block A and block B tRNA genes promoter elements. TB-block B binding is very strong and is responsible for TFIIIC-DNA stable anchoring, while tA-block A binding is weak and allows TFIIIB recruitment. The t95 subunit (encoded by TFC1 gene) belongs to the tA domain. We performed mutagenesis of the TFC1 gene segment that encodes a well-conserved region of t95 protein. We obtained a punctual thermosensitive mutant (E447K) and we studied the biochemical properties of mutant TFIIIC factor containing the t95-E447K subunit. .

Full textThe sS subunit of the RNA polymerase of d'E. Coli is required for the induction of genes in response to stressful conditions and in poor conditions of growth. Its targets largely overlap with those of s70 but despite the fact that sS and s70 recognize almost identical consensus sequences, many promoters are specifically transcribed by EsS in vivo. The sequence elements involved in selectivity of transcription initiation by EsS or Es70 are still unclear. The order to better understand what makes a promoter sS-dependent. A suppressor approach has allowed us to identify positions involved in transcription initiation by EsS. A further analysis of the variants obtained has led us to propose that EsS can recognize promoters by at least two different mechanisms, according to the promoter organization. This dual behavior of sS could offer the cell an additional regulation level of gene expression

Full textThe Hepatitis C virus (HCV) infection is responsible of acute and chronic hepatitis that may lead to cirrhosis and liver cancer. The HCV polymerase (HCV-pol) is an important target for antiviral therapies. First, we develop a screening method to search new inhibitors. Then, in absence of structural data on the replication complex, we report 3D models that are important for the interpretation of biochemical data. Moreover, I develop a crystallization protocol leading to the resolution of HCV-pol structure. It constitutes the base to obtain complexes structures with substrates or inhibitors. In parallel, we carry through the first structural analysis of HCV-pol in solution, using Small Angle X-ray Scattering (SAXS) in combination with X-ray crystallography and Normal Mode Analysis. We could thus assess the dimeric state, the conformation and the flexibility of HCV-pol at the atomic scale and propose a structural model of HCV-pol in solution

Full textHepatitis C (HCV) infection is a major health problem worldwide. The current therapy is not effective for half of treated patients thus, the development of new and specific drugs are urgently needed. Among the viral functions essential for viral replication, one of the most attractive targets for the development of drugs is the RNA dependant RNA polymerase (RdRp). Using a combinatorial approach (SELEX), DNA aptamers which bind specifically the HCV RdRp were selected. Three of these aptamers are able to inhibit the RNA synthesis in vitro. The binding and the inhibitory potential of 2 of these aptamers were associated with the random region. These aptamers, which display different secondary structures, inhibit specifically HCV RdRp by 2 distinct mechanisms : one is able to inhibit elongation whereas the other acts predominantly on initiation. The effect of the aptamers on HCV replication in a cellular context was studied with replicon system

Full textThe integrity of DNA is continuously challenged by a variety of endogenous and exogenous agents (e.g. ultraviolet light, cigarette smoke, environmental pollution, oxidative damage, etc.) that cause DNA lesions which interfere with proper cellular functions. Nucleotide Excision Repair (NER) mechanism removes helix-distorting DNA adducts such as UV-induced lesions and it exists in two distinct sub-pathways depending where DNA lesions are located within the genome. One of these sub pathways is directly linked to the DNA transcription by RNA Polymerase 2 (TCR). In the first part of this work, we demonstrated that a fully proficient NER mechanism is also necessary for repair of ribosomal DNA, transcribed by RNA polymerase 1 and accounting for the 60 % of the total cellular transcription. Furthermore, we identified and clarified the mechanism of two proteins responsible for the UV-dependent nucleolar repositioning of RNAP1 and rDNA observed during repair. In the second part of this work, we studied the molecular function of the XAB2 protein during NER repair and we demonstrated its involvement in the TCR process. In addition, we also shown the presence of XAB2 in a pre-mRNA splicing complex. Finally, we described the impact of XAB2 on RNAP2 mobility during the first steps of TCR repair, thus suggesting a role of XAB2 in the lesion recognition process
