Stereoviews of the interactions at the dimer interface. (Upper) Centered around the F–G β-hairpin, shown in the same orientation as Fig. 4. Contacting residues are in ball-and-stick format, and hydrogen bonds are shown as dashed lines. Protomers A and B are colored light gray and dark gray, respectively. (Lower) Close-up of the interactions at C–C′ loop. Residues are shown in ball-and-stick format, water molecule are shown as blue spheres, and hydrogen bonding is shown as a dashed line. Protomers A and B are in yellow and red, respectively.
