Position of B-cell epitope peptides on SARS-CoV-2 spike protein. In (A), positions of the six B-cell epitope peptides colored in green on a single protomer of SARS-CoV-2 spike protein trimer (EMD data resource: EMD-2256). The blank arrow indicates their position on the protomer. In (B), schematic organization of SARS-CoV-2 spike protein with the S1 and S2 subunits and their different domains and motifs is shown. The six synthetic peptides S1P1, S1P2, S2P3, S1P4, S1P5, and S2P6 peptides and their variants S1P1[F,T,S], S1P3[N], and S1P5[H] are mapped on the SARS-CoV-2 spike protein.
