Fig. 1: Identification of immunodominant candidate peptides.

a The flowchart illustrates the prediction and screening process of the RBD immunodominant peptides. b The amino acid sequences of candidate peptides LY54 and P67. RBM receptor-binding motif. c The spatial localization of candidate peptides LY54 and P67 in the RBD. The crystal structure of the SARS-CoV-2 RBD bound to ACE2 was obtained from the Protein Data Bank (PDB; code 6M0J). The red color shows the location of LY54 and the orange color shows the location of P67.
