A PF01609 DDE_Tnp_1 Transposase DDE domain Domain 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].

A PF02281 Dimer_Tnp_Tn5 Transposase Tn5 dimerisation domain Domain Transposons are mobile DNA sequences capable of replication and insertion into the chromosome. Typically transposons code for the transposase enzyme, which catalyses insertion, found between terminal inverted repeats. Tn5 has a unique method of self- regulation in which a truncated version of the transposase enzyme acts as an inhibitor [1]. The catalytic domain of the Tn5 transposon is found in Pfam:PF01609. This domain mediates dimerisation in the known structure. PFAM PF02281
