Figure 4
Binding mode of the C-terminus of Ub in the active site of SARS-CoV PLpro. (a) Schematic drawing in stereo showing the detailed interactions between the active site of the PLpro C112S mutant and the C-terminus of Ub. Hydrogen-bonding and ion-pair interactions are indicated by red dashed lines. (b) The OMIT FoFc electron-density map for the final four C-terminal residues of Ub at 1.4 Å resolution, contoured at 3.5σ. The interacting residues of PLpro are shown as sticks.
