FIG. 5. A comparison of the low resolution three-dimensional reconstruction of EV12-DAF[34] (A) and a space-filling representation of the EV12-DAF[34] complex (B), generated using the crystallographic co-ordinates for EV11 and DAF[34]. Radial depth-cueing emphasizes the distance between atoms or regions of density and the center of the virion such that dark colors are close to the center and light colors are farther away. EV12 (and EV11) is colored in shades of blue, whereas DAF[34] is colored in green. A space-filling representation of the EV7-DAF[1234] complex (30) (C) highlights the different orientation of DAF bound to these two viruses. The model deposited under PDB code 1M11 [PDB] contains -carbon atoms only; this view is therefore rendered with the atomic radii for each atom set to 3.5Å. EV7 is colored in shades of purple, and the receptor is in red. A close-up view of DAF[34] shown as in panel B but rotated 180^o about a vertical axis exposes the residues buried in the virus-receptor complex (D). Residues are colored according to their contribution to the total contact area ( 840 Å2); yellow (1 < 5%), orange (5 < 9%), and red (9%+). A close-up view of EV11 without the receptor in place exposes buried residues on the surface of the capsid that are colored according to the same scheme (E); the biological protomer is indicated.
