Mutants mapping of HA. Schematic representation of monomer structures of the H9 haemagglutinin molecule showing the locations of amino acid substitutions on HA1. Amino acid changes of escape mutants selected with or without homologous vaccine antibody against Ck/SH/F/98 (H9N2). The positions of the mutations sites are shown as yellow for 131 site, green for 145 site, apricot yellow for 181 site, and blue for 198 site. Red for receptor binding pocket of HA1 in H9 virus. Amino acid positions correspond to H9 numbering. Images were created with RasMol 2.7.3
