The RMSD of the apo Mpro, the “Mpro—natural products” complexes, and RMSF are aligned to Cα protein atoms. The RMSD of rosmarinic acid, curcumin, and quercetin is aligned with respect to their initial ligand positions. The shaded green, pink, and light blue colors indicate the I, II, and III protein domains, respectively, while yellow lines define the residues in the binding site.
