FIG 2 — Binding affinities of MpCoV-GX and -GD RBDs to human, mouse, and pangolin ACE2s. (A to C) Binding of MpCoV-GD RBD protein to human, mouse, and pangolin ACE2s. (D to F) Binding of MpCoV-GX RBD protein to human, mouse, and pangolin ACE2s. (G) Purified ACE2 proteins from humans (hACE2), pangolins (MpACE2), and mice (mACE2) and RBD proteins from MpCoV-GD (MpCoV-GD RBD) and MpCoV-GX (MpCoV-GX RBD). (H) Comparison of dissociation constants (K_D) between MpCoV-GD and -GX RBDs and human, mouse, and pangolin ACE2s. Binding was analyzed in comparison to MpCoV-GX RBD binding to human ACE2.
