Fig. 5: Structure of SARS-CoV-2 hexamer with the bound Tipiracil in surface representation.
From: Tipiracil binds to uridine site and inhibits Nsp15 endoribonuclease NendoU from SARS-CoV-2

Tipiracil bound to each subunit active site is shown with all atoms in color spheres (carbon, chlorine, nitrogen, oxygen in white, green, blue, and red, respectively).
