Fig. 4. Superposition of the Cα-chain (yellow) of the canine parvovirus VP2 capsid protein (PDB entry 1C8D) and the calculated surface of the VP2 capsid protein (pink) to the three-dimensional map of AAV2 (blue). The position of some residues of CPV-VP2 are labelled in red. Part of the inner surface of the capsid is shown in (A) with an almost straight on view to the eight-stranded β-barrel motif of CPV-VP2. The approximate positions of the symmetry axes are indicated in white. The views in (B) and (C) show different cross section through the protein shell.
