FIGURE 3.

Symmetrical dimer interactions. A, symmetrical interaction of molecule A (mol A) and B (mol B) are shown. The left panel shows a characteristic view of this form of dimer, and the right panel displays a 90° rotated view. B, wall-eye stereo view of the interface of the symmetrical interactions. Polar contacts between the residues and molecules are shown by dotted lines. Red spheres represent the water molecules bound to the protein. C, surface representation of the symmetrical Hpx-14 dimer interface. The residues involved in the interaction (Asp³⁸⁵, Thr⁴¹², and Tyr⁴³⁶) are colored in red and annotated. D, each blade is colored differently to show orientation of the molecules. Blue, blade I; green, blade II; yellow, blade III; red, blade IV.
