FIG. 2.
Comparison of known adenovirus fiber head structures. Cartoon colors are generated by PYMOL (10) according to relative B-values. Blue shows lowest B-values, and red shows highest B-values. The molecular surface and electrostatic surface potential was calculated using GRASP (27). Colors range from red (potential of −10 kT) to blue (+10 kT). (A) Ad41 short fiber head, structure at 1.5 Å resolution, pH 5. (B) Ad2 fiber head (34). (C) Ad12 fiber head (5). (D) Ad37 fiber head (6).
