Structural comparison of AAV2, AAV7, and AAV11–13. (A) Structural superposition of AAV2 (blue), AAV7 (cyan), AAV11 (burgundy), AAV12 (salmon), and AAV13 (wheat) shown as ribbon diagrams. The positions of β-strands, the N- and C-terminus, the variable regions (VRs), and the icosahedral 2-, 3-, and 5-fold axis are indicated. This figure was generated using PyMol [60]. (B) Cα–Cα distance plot (in Å) for the AAV7 and AAV11–13 residues relative to AAV2 of the superposed viral protein (VP) structures. The VRs are indicated and the overall VP Cα-RMSD (root mean square deviation) compared to AAV2 shown. The dashed line marks the Cα–Cα distance variation of 1 Å.
