Transposase proteins are necessary for efficient DNA transposition. This domain is a member of the DDE superfamily, which contain three carboxylate residues that are believed to be responsible for coordinating metal ions needed for catalysis. The catalytic activity of this enzyme involves DNA cleavage at a specific site followed by a strand transfer reaction [3]. This family contains transposases for IS4 Swiss:P03835 [1], IS421 Swiss:P11901 [2], IS5377 Swiss:Q45620, IS427 [4], IS402 [5], IS1355 Swiss:O69604, IS5, which was original isolated in bacteriophage lambda [6].
