Fig. 4.

Relative location of β3-β4, β9-β10 and β14-β15 loop regions in the complex of the 4A8 antibody with the SARS-CoV-2 NTD. (A) Position of Ala 67, His 69, Asp 80 (β3-β4 loop) and Tyr 248 (β14-β15 loop). (B) Position of Val 143 (β9-β10 loop). Blue color indicates the β9-β10 loop residues 141–158. Structures are based on PDB 7C2L (Cryo-EM structure of 4A8:SARS-CoV-2 S complex).
