a The ribbon representation of the crystal structure of the SARS-CoV-2 Mpro from PDBID: 6Y2E. Domains I, II and III are displayed in pink, yellow and light blue (teal) respectively. The connection region between II and III are in red (C), green (N) and violet (binding cleft). b The ribbon representation of the crystal structure of the SARS-CoV-2 Mpro from PDBID: 6Y2F. Domains I, II and III are displayed in red, yellow and blue respectively. The connection region between II and III is in white and the catalytic dyad residues (His41 and Cys145) are in solid sp
