title: [Nucleotide sequence and properties of a transposon-like structure cloned from a Bordetella pertussis chromosome].
abstract: The 2.3 kb BamHI-EcoRI subclone has been isolated and sequenced from the 15 kb BamHI chromosomal fragment of Bordetella pertussis comprising also the vir gene. The sequence contained one copy of a transposon-like structure, very similar to the RSs of B. pertussis recently characterized, the unique sequence of B. pertussis chromosomal DNA and an inverted sequence complementary to 402 bp of 3' end of the B. pertussis RS element. The fragment of plasmid pUC4K containing the gene for kanamycin resistance (Km) was integrated in the XhoI site of the unique portion of the transposon-like structure of plasmid DNA (Ap(r), Km(r)). The clones in amount of 2% tested had the Ap-S phenotype. The recombinant plasmid from the Ap(s) phenotype clones lost one of the repeats and a portion of the gene bla as a result of deletion. The conclusion is drawn that RSs of B. pertussis stimulate the formation of deletions.
