Figure 3: Sequence conservation within H7 HA. The residue conservation among all non-identical, full-length H7N9 human isolates was mapped onto a monomer of H7 HA trimer (Protein Data Bank ID: 4 LN3); (a) HA1 and (b) HA2 subunits were coloured according to the sequence conservation key. The HA1/HA2 subunit of the same monomer is in yellow. As observed, H7 HA sequences reported till date are well conserved, hence represented in blue according to the sequence conservation key. Rest of HA (excluding HA1/HA2) is shown in grey. The figure was rendered using Chimera
