Fig 1.
The view down the icosahedral five-fold axis (A) and a cut-away side view (B) from the crystal structure of MVMp VP2-only VLPs (grey ribbon) (PDB ID 1Z14: Kontou et al., 2005) show that the five-fold channel is constructed from symmetry-related VP2 molecules. The position of L172 (green) and V40 (yellow) are shown with their side chains rendered as ball and sticks.
