[Genetic properties of transposons Tn6-1, Tn6-2 and Tn19-1].

The level and range transposition of the transposons Tn6-1, Tn6-2, Tn19-1, and their ability to influence plasmid transfer has been studied. The widest range of transposition was shown for transposon Tn6-2. Insertions of each of the studied transposons into different conjugative plasmids genomes resulted in change of frequencies of plasmids transfer and change of plasmids mobilization activity.
