Tn3 family transposase
This family includes transposases of Tn3, Tn21, Tn1721, Tn2501, Tn3926 transposons from E-coli. The specific binding of the Tn3 transposase to DNA has been demonstrated. Sequence analysis has suggested that the invariant triad of Asp689, Asp765, Glu895 (numbering as in Tn3) may correspond to the D-D-35-E motif previously implicated in the catalysis of numerous transposases [2].
