| Outline of Final Research Achievements |
In DNA replication restart, systematic association and dissociation of several proteins are occurred on DNA. In this application, we performed the structure and function analysis of the proteins (PriA、PriB、DnaT、PriC、DnaB ) involved in replication restart in Escherichia coli. In DnaT, we examined the oligomeric state of the N-terminal domain and the ssDNA (singles-stranded DNA) dissociation activity from PriB-ssDNA (singles-stranded DNA) complex by the linker region between the N-terminal and C-terminal domains, which is involved in the binding to PriB. Moreover, we examined the interaction between PriC and DnaB. Together with these results, we contributed elucidating the mechanism in replication restart.
