Figure 4.
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).
