SPR measurement and crystal structure of the Omicron RBD complexed with Beta-55 and EY6A Fabs, related to Figure 7
(A) SPR measurements.
(B) Ternary complex of the Omicron RBD (gray)/Beta-55 (heavy chain red, light chain blue)/EY6A (heavy chain salmon, light chain cyan).
(C) Electron density map showing the density for the mutated residues at 446, 498, 501, and 505, and their interactions with the CDR-H3 of Beta-55.
(D and E) Comparison of the slightly different binding mode of Beta-55 to Beta-24 (cyan in D) and Beta-40 (cyan in E), the close-up boxes show details of the interactions with Beta-24 and Beta-40 explaining the knockout of Beta-24 and the resilience of Beta-40.
