Figure 8
Heatmap presenting the differences (tile color) between the mean coordinates of Cα atoms of all of the 3CLpro structures and the Cα coordinates for each residue (x axis) in each structure (y axis). Light tile colors indicate coordinates close to the mean, whereas dark colors represent Cα coordinates deviating from the mean. The dendrogram on the left presents a clustering of the structures according to their Cα deviations, with the colors of the leaves representing structural polymorphs (for details, see Supplementary Fig. S1). Residues directly involved in forming the catalytic site (His41, Cys145, His164 and Asp187) are marked with asterisks.
