FIGURE 1. Overall structure of the SCV RBD in complex with the neutralizing antibody Fab m396. The SCV RBD is in green, and the prominent neutralizing site comprising residues 482 through 491 ( 6– 7 loop) is in red. The side chains of two important residues, Ile-489 and Tyr-491, of the loop are shown as sticks. A portion of the structure shown in brown constitutes the 16 amino acid residues that were not observed in the RBD·ACE2 structure (20). The light and heavy chains of the Fab are shown in cyan and yellow, respectively, with labeled CDRs, H1, H2, H3, and L3, which make contacts with the RBD.
