Comparison of transposase domains of Trem elements and related fungal transposases. ClustalW alignment of the conserved domains HTH_psq, CENPB and DDE of Trem elements with the domains of the fungal transposable elements Mariner1_AF and Mariner5_AF from Aspergillus fumigatus, Mariner2_AO, Mariner3_AO from Aspergillus oryzae, Mariner9_AN from Aspergillus nidulans, Tan1 from Aspergillus niger and Pot 2 from Magnaporthe grisea. The Pogo element from Drosophila is also included to illustrate the conservation between kingdoms. Sequences corresponding to the conserved residues are shaded in black (100% conservation), dark ash (80% conservation) and ash (60% conservation). The DDD motif, characteristic of the catalytic domain of transposases, is highlighted in blue. Numbers indicate distance along TremA.
