Structural mapping in S protein of the segments that match the antigenic proteins from different pathogens. A The location of the segments on the structure is marked by yellow patches. Different chains are represented in different colors. The S1 and S2 subunits have been solved independently. B B-cell epitope prediction from the sequence of SARS-CoV-2 protein. The sequences identified from the similarity analysis are marked in blue. Segments in which amino acid scores are above 0.5 are putative epitope sites. C Cumulative SASA measures for each of the putative antigenic sites calculated using different probe radii
