The left panel shows the docking results of sunitinib (stick representation; indicated by a small arrow) to the MERS-CoV PLpro (cartoon representation). MERS-CoV PLpro domains were labeled next to the corresponding domain. The right panel shows a surface representation of the binding pocket of sunitinib (indicated by a small arrow) in the upper box. The lower box shows the interaction residues of PLpro with the sunitinib molecule.
