Fig. 3 — Comparative interacting residues of host ACE2 with the Omicron RBD with respect to hACE2. By using the ClusPro server for molecular docking, the interactions between hACE2 and other mammalian host ACE2 against Omicron RBD were evaluated and analysed in PDBSum as described in the text. The number of interacting residues of host ACE2 receptors and the identical residues to that of the hACE2 were calculated
