Figure 1: Colored trimeric proteins by crystal symmetry class. Each monomer in the 5-fold axis turret is in a different crystal symmetry class but is given the same color since they are not involved in crystal contacts. Note that under icosahedral symmetry every monomer is identical. | Figure 2: Noncrystallographic symmetric unit. |
Figure 3: Crystal unit cell contains two full particles. The one unique contact interface in the crystal is between light and dark blue trimers.
Figure 4: Four different depictions of crystal contact residues shown in red: ribbons, atoms as spheres, low resolution surface, high resolution surface.
