Full textDNA is the major carrier of genetic information in prokaryotic and eukaryotic cells and its integrity is vital for the survival of cells. However, DNA is under pressure of damages caused by both exogenous and endogenous factors. Double strand break (DSB) is one of the most toxic DNA damages and even one unrepaired DSB is lethal to cells. Cells have evolved several pathways to repair DSBs, including non-homologous end joining (NHEJ), and homologous recombination (HR). HR is an error free repair pathway that uses an intact homologous sequence as a template to repair the damage. This involves identifying the homologous sequence among the mega bases of the genome and in the nuclear volume of eukaryotic cells. At the molecular level, DNA sampling and strand invasion of the homologous dsDNA is achieved by a nucleoprotein filament (NPF), formed by the recombinase, RecA in bacteria and Rad51 in eukaryotes, coating ssDNA. This mechanism has been extensively studied in vitro and in vivo through genetic and molecular approaches at the level of cell populations, but its dynamics could not be studied in living cells due to lack of functional fluorescent version of Rad51. Thus, how broken DNA can find a homologous sequence in the volume of the nucleus and among the megabases of DNA remains mysterious.Thanks to structural insights from our collaborator Raphael Guerois (I2BC, CEA, France), we developed and characterized the first functional, internally tagged version of a recombinase in the yeast S. cerevisiae. Following the induction of unique DSB, we observe for the first time in living cells, Rad51 forming micrometer long filaments spanning across the whole nucleus and contacting the donor sequence. As predicted from genetic and in vitro data, their formation requires the recombinase loader Rad52 and the formation of long stretch of ssDNA. Furthermore, emerging filaments adopt a variety of shapes, not reported in vitro and modulated by Rad51 ancillary factors, shedding new light on the function of these factors in living cells.In contrast to what has been reported for RecA filaments in bacteria, Rad51 filaments show a surprisingly dynamic behavior: with frequent compaction events followed by re-extension providing opportunities for the NPF to be projected into a different nuclear area, and thus explore new genomic regions. Biophysical modeling of the homology search process by our collaborator Leonid Mirny (MIT, USA) reveals that these cycles of compaction/extension constitute a very robust strategy for a unique identity to find its target in the nuclear space

Full textIn this PhD thesis, the SD behavior is studied in various environments (in solution and within protein). In the first part, the physico-chemical properties of SD molecules in solution are explored in a joint experimental and theoretical (DFT and TD-DFT) investigation. The latter demonstrates the dianionic nature of SD compounds in physiological conditions and indicates that accounting for vibronic coupling is crucial to reproduce the bandshape of the absorption spectra. The second part is focused on the modeling of SD2- complexes within a carrier protein, the human serum albumin (HSA), which is essential for the drug transport process through the human body. HSA appears to be an excellent candidate to carry SD2- compounds into cancer cells. Without any cristallographic structure of HSA-SD2- complex, molecular modelling is the only predictive tool to obtain structural data. We performed molecular docking and molecular dynamic methodology to (i) identify the key residues, (ii) investigate the complex energies by MM-GBSA calculations and (iii) determine the most potent binding sites to host SD2- derivatives

Full textIn recent years, the need for recombinant proteins has substantially increased in various bio-industry activities. However, actual recombinant processes are still limited by the lack of markers allowing real-time expression and purification monitoring of target proteins, by inclusion bodies formation and by low quality of purity of the products. To overcome these difficulties, we have developed a new process for production and purification of recombinant proteins in Escherichia coli. The method combines the use of a multifunctional expression cassette, termed Multitags and an immobilized modified TEV protease on a streptavidin matrix. The Multitags contains, its N-terminus, two affinity purification tags (10xHis and SBP) and as a marker tag, the heme-binding domain of cytochrome b5 followed by the TEV cleavage site. Using two model proteins (MyRIP and Pfu DNA polymerase), we have demonstrated the visual and the quantitative monitoring capability of the cytochrome b5 during the expression and purification steps. When expressed in E. coli KRX more than 90% of both fusion proteins were produced in a soluble form. In addition, high purity (99%) of Multitags-MyRIP and Multitags-Pfu was achieved after two consecutive affinity purification steps using the dual affinity tag. We also produced the wild-type and the S219V mutant TEV proteases fused to the Streptag II affinity sequence and realized their affinity immobilization on a streptavidin-agarose matrix. The characterization of the proteolytic columns and their application to the recombinant model proteins demonstrated the advantage of this immobilization method in terms of retaining activities, enzyme stabilities, possibility of reuse and simplification of the cleavage downstream steps.In conclusion, this study allowed the development and the validation of innovative tools for expression and purification of recombinant proteins

Full textIntracellular immunization consists in the expression of antibody fragments inside the cell that bind to a protein and interfer with its function. The main problem limiting the use of intrabodies is the absence of disulfide bonds in the reducing conditions pertaining in the cell cytoplasm. We used the scFv13R4 antibody fragment, selected for its high soluble expression level in the cytoplasm, to construct, by loop (CDR) grafting, an antibody fragment against the E6 protein of human papillomavirus type 16. After several optimization steps, cytoplasmic soluble expression of the grafted anti-E6-protein antibody fragment was comparable to that of the original antibody (13R4). To circumvent this long procedure, we designed and constructed an optimised library of antibody fragments for intracellular immunization, based on the scFv13R4 framework with randomized CDR3 loops mimicking the natural diversity of human CDR loop sequences. This library has been tested against several proteins, demonstrating that it is now possible to rapidly obtain intrabodies against any protein

Full textBlood coagulation results in sequential activation of plasma proenzyme to their enzyme form. This burst of activation is very selective and auto-regulated. It is the last enzyme (thrombin) who controls directely and indirectely this cascade. Thrombin activity is regulated through three mechanisms 1) an auto-control of its generation, 2) modulation by thrombomodulin and 3) neutralization by antithrombin. The last two mechanisms were discussed in this thesis, especially Protein C activation which is the only inductible anticoagulant system. Direct neutralization of thrombin by antithrombin was investigated through the characterization of a monoclonal antibody that selectively recognizes complexed antithrombin. This antibody reacts with none of the monomeric conformers of antithrombin. These observations limit drastically the possible locations of the defeated protease within the complex. .

Full textHyperthermophilic archaea (HA) are found in high-temperature environments and grow optimally above 80°C. Usually, cells exposed to heat stress display an increased sensitivity to agents inducing double-stranded DNA breaks (DSBs). Studies in Eukaryotes and Bacteria have revealed that homologous recombination (HR) plays a crucial role not only in DNA DSBs repair, but also in the collapsed/stalled DNA replication fork restart.Recombinase and various HR-associated enzymes in archaea specifically resemble the eukaryotic homologues, rather than bacterial homologues.Furthermore, several studies have demonstrated the necessity of HR proteins in HA, suggesting that, HR is an important mechanism in HA. HR influencing genome stability has been well studied in Eukaryotes andBacteria, however, few of its functional properties have been studied in HA.To better understand how HR mechanism is involved in the archaeal genome maintenance process, a previous work proposed a protein-protein interaction network based on Pyrococcus abyssi proteins. Through the network, new interactions involving proteins from DNA replication and DNA recombination were highlighted. The targets of the study presented here for two protein interaction are: PCNA/Mre11-rad50 complex (MR complex) and Primase/RadA. For the first time in P. furiosus, we showed both physical and functional interactions between PCNA (Maestro in DNA replication) and MR complex (initiator of HR). We have identified a PCNA-interaction motif (PIP) located in the C-terminal of Mre11, and shown that PCNA stimulated MR complex endonuclease cleavage proximal to the s’ strand of DNA DSBs at physiological ionic strength. For the second interaction, we have purified the proteins PabRadA/PfuRadA, PabPrimase and PabP41, and confirmed its enzymatic functions. However, we were not able to characterize the function of Primase/RadA association
