Transposition of Bordetella pertussis transposon in E. coli chromosome has been studied on a model of exclusion of donor multicopy pKK3 plasmid with coumermicin. TnBP3 induced the formation of co-integrates between the plasmid and chromosome. The structure of co-integrate was determined. Facts of exclusion of integrated structure and transposon transposition within integrated plasmid into new sites on a recipient chromosome were detected. Relationship between these processes and activity of bacterial cell recombination system has been determined.
