Fig. 2: Interaction interface in the RBD/dACE2 complex and the RBD/hACE2 complex.
From: The molecular basis for SARS-CoV-2 binding to dog ACE2
a Residue interactions in the RBD/dACE2 interface. b Residue interactions in the RBD/hACE2 (PDB ID: 6LZG) interface. The black lines represent Van der Waals (vdw) interactions, and the red lines represent hydrogen bonds or salt bridges (a, b). c The residues involved in interface interactions in the RBD/dACE2 complex. d The residues involved in interface interactions in the RBD/hACE2 complex. The interaction interface in RBD is divided into two contact regions (CR1 and CR2), and their corresponding contact regions in the residues in dACE2 (c) or hACE2 (d) are named CR1’ and CR2’, respectively. The residues involved in interface contacts are shown as the sticks representation (c, d).
