I manipulate E. coli by the use of P1 transductions, gene knockouts etc, and I
was wondering what, if any, role was played by REP elements in these events.
One gene I am interested in has a single REP sequence immediately downstream,
and we are getting some strange results... I am aware that they are thought to
be involved in chromosomal rearrangements, bind DNA gyrase... but no-one seems
to sure as to their actual function. Could they be affecting the outcome of my
experiments? Any pointers greatly appreciated!
Thanks in advance,
