FIG. 4.
Conformation of the CAR binding AB loop. Comparative structures of a region implicated in CAR-binding in the AB loop after structural superposition of different adenovirus fiber heads using COOT. Note that the conformation of Ad37 and Ad12 AB loops corresponds to that found in complex with CAR. Red: Ad12 fiber head, green: Ad2 fiber head, blue: Ad3 fiber head, yellow: Ad5 fiber head, magenta: Ad37 fiber head (as found in complex with CAR), gray: Ad41 short fiber head.
