| Abstract: | The transposons Tn3611 (HgR, 9.0 kb) and Tn3613 (SmRCmRKmRSuRHgR, 24.0 kb) were discovered in the chromosome of Pseudomonas aeruginosa BS205. The physical and genetic maps of these transposons were constructed using restriction endonucleases EcoRI, BamHI, SalI, HindIII. Genes of the mer operon, tnpA and tnpR were localized in the Tn3611 transposon, the genes DHPS-II, aad, tnpA, tnpR being situated in the map of the Tn3613 transposon. It was established that the Tn3611 belongs to the class of Tn3-like transposons and the Tn3613 is a complex transposon flanked by inverted repeats 2.2 kb in size, the transposon comprising both Tn3611 and a migrating sequence. |
