From: Characterization of a functional insertion sequence ISSau2 from Staphylococcus aureus
The structure of ISSau2. a ISSau2 encodes a fusion protein (OrfAB, transposase), which contains two proteins OrfA (251aa) and OrfB (297aa), flanked by two imperfect inverted repeats (IRL and IRR). The frameshift site is shown as a dotted line. A HTH motif (70-120aa) is designated as a purple rectangle, and a DDE catalytic domain is also indicated. b The nucleotide sequences of assumed IRL and IRR are aligned
