Figure 2. Ribbon representations of the TT1887 tetramer (A) and the TT1465 hexamer (B) (stereo view). Each monomer is colored differently. Electrostatic surface representations of the TT1887 monomer (C) and the TT1465 monomer (D). Blue and red surfaces represent positive and negative potentials, respectively. The locations of putative active sites are shown with arrows.
