Figure 6From: Genomic characterization of equine influenza A subtype H3N8 viruses by long read sequencing and functional analyses of the PB1-F2 virulence factor of A/equine/Paris/1/2018Positions of the amino acid substitutions on the surface of N8 between the FC1 vaccine strain A/equine/Ohio/1/2003 and the A/equine/Paris/1/2018 strain. Only the head of NA is represented. Amino acid changes are colored blue. The 3D structure template is the PDB accession number 2HT5.Back to article page
