When the HA amino acid substitutions are accumulated in the repertoire of infl uenza virus strains, they are mostly on the exposed surface of the HA glycoprotein except for the receptor binding site, the fusion peptide, and the amino acids that accommodate the fusion peptide before HA structural changes for membrane fusion (Wilson et al. The next 18 amino acids form part of the pocket that accommodates the hydrophobic fusion peptide in the metastable HA structure on the infl uenza virion prior to virus entry.	./cache/cord-007792-596jxrm5.txt	./txt/cord-007792-596jxrm5.txt
