In an effort to gain insights into the role of ${it D. radiodurans}$ RecFOR proteins in homologous recombination, we generated ${it recF}$, ${it recO}$ and ${it recR}$ disruptant strains and characterized the disruption effects. Disruption of ${it recR}$ resulted in severe reduction of the transformation efficiency. On the other hand, the ${it recF}$ disruptant strain was the most sensitive phenotype to $$gamma$$ rays, UV irradiation and mitomycin C among the three disruptants. In the ${it recF}$ disruptant strain, the intracellular level of the LexA1 protein did not decrease following $$gamma$$ irradiation. These results demonstrate that the RecF protein plays a crucial role in the homologous recombination repair process by facilitating RecA activation. Thus, the RecF and RecR proteins are involved in the RecA activation and the stability of incoming DNA, respectively, during RecA-mediated homologous recombination processes that initiated the ESDSA pathway in ${it D. radiodurans}$.

In an effort to gain an insight into the role of the RecFOR in DNA repair through homologous recombination in ${it Deinococcus radiodurans}$, we generated a RecFOR disruptant strains and characterized the disruption effects. The RecF disruptant strain exhibited sensitivity to DNA-damaging agents, suggesting that RecF has a crucial role in DNA repair. This result indicates that RecF takes an important role in the RecA activation in the homologous recombination process with DNA damage. While, the recombination assay revealed that RecR is essential for the process of homologous intermolecular recombination, suggesting that RecR is important factor in the homologous recombination process without DNA damage. The importance of RecF and RecR in the homologous recombination processes is reversed due to the existence of DNA damage. Therefore, ${it D. radiodurans}$ will use the different homologous recombination processes through the RecFOR or RecOR, respectively.

${it O}$-sialoglycoprotein endopeptidase (Gcp) gene has been annotated with, such as ${it Saccharomyces cerevisiae}$ and ${it E. coli}$ are classified as essential genes. However, in ${it Thermus thermophilus}$ and ${it Synechocystis}$ sp. PCC6803, it is not essential. As its function, ${it gcp}$ ortholog (${it qri7}$) mutants in ${it S. cerevisiae}$ mitochondrial DNA are the loss of genomic DNA. In ${it T. thermophilus}$, ${it gcp}$ ortholog disruptant was reported that it growth was suppressed under high salt concentration. Mutual relationships between organisms on the role of gcp ortholog has not been found. The study, we performed a genetic analysis of functional roles in ${it D. rdiodurans}$ Gcp ortholog encoding (${it DrygjD}$), YeaZ ortholog (${it DryeaZ}$), and Gcp ortholog encoding (${it TtygjD}$), YeaZ ortholog (${it TtyeaZ}$) in ${it Thermus thermophilus}$
