Deletion analysis has shown that the segment at the IS50 inside (I) end that is needed for efficient transposition is ~19 bp long. Dam methylation at two 5′ GATC sequences within this segment decreases I-end transposition activity. A third 5′ GATC sequence is present at bp 21-24 of the I end. The comparisons presented here show that extension of the I end from 19 to 24 bp decreases its transposition activity in dam cells 5- to 50-fold, depending on the overall transposon structure.
