Figure 3

The schematic representation of some possible conserved epitopes on the SARS-CoV-2 SP (Black: positions occurring in a set of predicted epitopes; Red: positions occurring in 2 sets of predicted epitopes; Green: positions present in 3 sets of predicted epitopes). (A) Schematic structure of the SARS-CoV-2 spike protein. (B) Structure of the SARS-CoV-2 S1 subunit showing the conserved epitopes on the NTD and RBD. (C) Structure of the SARS-CoV-2 S2 subunit showing the conserved epitopes on the FP and HR.
