| Outline of Final Research Achievements |
This study functionally and structurally analyzed, using various in vitro reconstitution assays, replication initiation complexes in Escherichia coli and complexes which regulate activity of DnaA protein, a major factor in replication initiation complexes. First, important mechanisms supporting complex formation of DnaA protein and DNA unwinding function in replication initiation complexes were revealed. Second, important mechanisms supporting complex formation of DnaA protein with chromosomal non-coding DNA elements, DARS and datA, as well as functional coupling of these complexes with the cell cycle were revealed.
