Figure 7. Alignment of the amino acid sequence of Mos1 with six other mariner transposases and five Tc1-family transposases.
The secondary structure elements of Mos1 transposase in the Mos1 STC are shown above the alignment. A red star below the alignment denotes the position of each of the catalytic acidic residues of the DDE/D triad. The third residue of this triad is typically D in the mariner sub-family and E in the Tc sub-family. The key residues involved in target DNA stabilisation in the Mos1 STC are highlighted in blue and marked by a blue dot. The figure was created with ESPript 3.0 (http://espript.ibcp.fr/ESPript/cgi-bin/ESPript.cgi).
