Overview of binding changes for delta and omicron variants relative to WT Color coding is the same for all charts. For the FCD to furin binding, R1-R6 correspond to 681–686, except for the alternate omicron sequence 679–684. For clarity, RBD binding to P4A1 and CR3022 Abs are not shown. Full residue interaction tables measured by average hydrogen bound strengths are provided in the Supplementary Material.
