Transposition activity is generally maintained at a low level. An often-cited reason for this is that high activities and the accompanying mutagenic effect of genome rearrangements would be detrimental to the host cell (see [1]). Endogenous transposase promoters, in contrast to those assembled by the juxtaposition of -10 and -35 hexamers in those IS families whose transposition passes through a double-strand circular transposon intermediate, are generally weak and many are partially located in the terminal IRs. This would enable their autoregulation by Tpase binding.
