Figure 4 Electrostatic surface potential for the monomer (A),
dimer (B) and tetramer (C). A highly acidic surface is visible
in the oligomers. The monomer displays several hydrophobic
areas, especially in the N-terminal furrow, along the hinge
helix and on the underside of the CTD. These patches are
efficiently shielded from solvent in the oligomers. Regions used
for contacts a–d (Figure 3) are indicated. The figure was
produced with GRASP (Nicholls et al., 1991).
