CPV Capsid and subunit organization. The 2CAS model of CPV was downloaded from the VIPER database. The expanded inset shows a single VP2 subunit ribbon diagram with N-terminus in blue and C-terminus in red. B. Accessible surface lysines profile of CPV capsid. Data shown was downloaded from VIPER database. Lysine residues in the VP2 subunit are shown on X-axis (total of 20 per subunit) and the effective radius multiplied by the solvent accessible surface area (SASA) is shown in blue on Y-axis on the left side. The radial distance of each residue is also shown on Y-axis in magenta. Coinciding high values on Y-axis suggest residues that are (i) highly accessible, (ii) moderately accessible and (iii) accessible to a lesser extent.
