..31 bp from ISS1S and ISS1T, respectively, and in 2 of 226 amino acids in the deduced sequence of the putative transposase. IS946 has perfect 18-bp terminal inverted repeats, identical to ISS1, and similarly generated 8-bp direct ..

..On pWV05, ISS1W is flanked on one side by only part of a second IS element, indicating that pWV05 evolved as a deletion derivative of a precursor plasmid that carried at least two IS elements. ..
