3D structure of SARS-CoV-2 Mpro, in two different views. One protomer of the dimer is shown in light blue, the other one in orange. Domains are labeled by Roman numbers. Amino-acid residues of the catalytic site are indicated as yellow and blue spheres, for Cys145 and His41, respectively. An asterisk marks a residue from protomer B (orange). Black spheres indicate the positions of Ala285 of each of the two domains III. Chain termini are labeled N and C for molecule A (light blue) and N* and C* for molecule B (orange).
