| Archaea are micro-organisms present in all ecosystems, but are majoritary present in extremophilic environments. Hyperthermophilic Archaea, as Pyrococcus abyssi, are permanently exposed at temperature which can increase the rate of spontaneous DNA damage. It is probable that hyperthermophilic Archaea possess efficient molecular mechanism to duplicate, maintain and stabilize their genomes. The aim of this project was to investigate the interaction network involved in the process of DNA replication and DNA repair. The methodological approach consists in the coupling of pull-down with mass spectrometry identification of interacting partners. A preliminary interaction network was identified that was composed of new proteins as well as unsuspected interactions... |
