HRV-QPM protomers were replicated and mapped onto an icosahedral lattice (T = 1 configuration; Figure 5A ), rendered in 3D and depth cued in order to predict capsid structures. Since HRV-QPM protein and protomer structures were inferred by homology to their closest available relatives, these capsids (HRV-16 and HRV-14) were produced from the available empirical data, using the same approach. Visual comparisons revealed that the deletions in the HRV-QPM VP1 most obviously reduced the size of protrusions around the 5-fold axis of the capsid.
