Fig. 3.
Top: View of the icosahedral asymmetric unit bounded by adjacent five- and threefold axes, outlining residues on the viral surface. Shown are the limits of the canyon, arbitrarily demarcated by a 138 Å radial distance from the viral center [28], and the ICAM-1 footprint (stippled). Improved resolution of the electron density could only marginally alter the HRV residues at the virus:receptor interface. Left and right: Enlarged view of the residues in the ICAM-1 footprint showing (right) the residues which, when mutated, affect viral attachment [5], and (left) the residues altered in structure by the binding of antiviral compounds that inhibit attachment and uncoating [32]
