Figure 3.
FIG. 3. Homology model of Ad2 knob bound to CAR D1. The
x-ray structure of Ad2 knob was overlaid onto Ad12 knob in the
x-ray structure of the Ad12 knob-CAR D1 complex. For simplicity,
only one monomer of the knob trimer is shown. The surface of CAR
D1 (space-filling model on left) is colored blue. Superimposed
ribbon structures of Ad2 knob and Ad12 knob are colored cyan and
green, respectively. Side chain residues of Ad12 knob contacting
CAR D1 are shown in gray except for side chains of Ser489 and
Pro417, which are shown in red. Ad2 knob Ser408 and Tyr477 side
chains are colored yellow.
