Figure 1. Comparative interacting residues of (A) RBD of SARS-CoV-2 variants and (B) hACE2 with respect of the Omicron variant. The protein-protein interaction between hACE2 and SARS-CoV-2 RBD was studied by performing molecular docking using ClusPro server (https://cluspro.org) and analyzed in PDBSum. The number of interacting residues were calculated and identical residues to that of the Omicron variant were calculated.
