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).
