Figure 4. A surface view of a dimer and DNA binding model of S. solfataricus transposase. A, the electrostatic potential at the molecular surface of a dimer of S. solfataricus transposase is shown (blue, positive; red, negative). B, stem-loop DNA binding to S. solfataricus transposase modeled by superposition of S. solfataricus transposase (Mn^2+-free, blue) and the H. pylori IS608 transposase (PDB code 2A6O, orange).
