Figure 2From: A Tn5051-like mer-containing transposon identified in a heavy metal tolerant strain Achromobacter sp. AO22Comparison of terminal IRs of Tn AO22 with IRs of Tn 501 and Tn 21. Boldface bases: conserved positions for the efficient recognition by the Tn21 transposase; shaded sequences: Eco RI sites; t: IRs at the tnpA end and 'm' the mer end.Back to article page
