My. Kirillov et al., REPEATED SEQUENCES ISOLATED FROM BORDETELLA-PERTUSSIS INDUCE DNA REARRANGEMENTS AND DELETIONS AT HIGH-FREQUENCY, Gene, 166(1), 1995, pp. 111-116
Two repeated sequences (RS) from Bordetella pei tussis were cloned in
Escherichia coli and sequenced. The RS, called RSBP1 and RSBP3, are hi
ghly homologous to other B. pertussis RS. The recombinant plasmids con
taining RSBP1 and RSBP3 or transposon-like structures of these element
s were not stable but segregated plasmids with deletions or rearranged
DNA. RS of B. per tussis seem to be able to stimulate both intra- and
inter-genomic RecA-independent recombination events. In at least one
case, the observed deletion had occurred precisely between the RS term
inus and a site with sequence homology to the terminus. The high frequ
ency rearrangements associated with the RS imply that the RS are trans
posable elements.
