Binding of three fragments in more closed published 3CLpro structures (cyan) compared with this study with a more open 3CLpro conformation (grey). Comparison of the same small molecule in the two different structures shows (a) a translation or (b, c) a rotation of the upper-left ring of fragments corresponding to PDB entries 5rh0, 5rh1 and 5r83, respectively. The position of Met49 shows the more open binding-site conformation used in this study. |
