Figure 2.
Crystal structure of the SARS-CoV-1 S RBD (PDB id 2AJF, chain E) and the modeled SARS-CoV-2 S RBD (wildtype). See text for details regarding the modeling aspects. These macromolecules are shown, respectively, in blue and red in a ribbon representation. The root-mean-square deviation (RMSD) between these structures is equal to 0.64 Å.
