Fig. 4From: Normal modes analysis and surface electrostatics of haemagglutinin proteins as fingerprints for high pathogenic type A influenza virusesMultiple Sequence Alignment of RBD regions showing different flexibility. Sequences are identified by UniProtKb AC followed by H for HPAI and L for LPAI. Numbers for the first and last residue of each sequence block/RBD region are reported; blocks are highlighted using the same colours as boxes defining regions in Fig. 3. Changes are highlighted by bold aminoacid one-letter codesBack to article page
