Antigenic sites A-D [11] were mapped to our consensus sequences and tabulated with overlapping MEME motif, entropy values and post-translational modifications sites. Site A average entropy is based on amino acid position 144 and 145, while site B average entropy is based on amino acid position 188 and 189.
