Figure 4. Identification of the super docking position of the control ligand (serpentine) inside the hACE2 receptor as well as the hydrogen and hydrophobic interactions involvement inside the ‘serpentine–hACE2 receptor’ complex. The distances among the amino acid residues are mentioned using red lines where the hydrogen bonds are the pink lines (A) as 3D confirmation. Besides, the most stable hydrogen bonds (green line) and hydrophobic interactions (red lines) are represented in 2D.
