Identification and Chronological Analysis of Genomic Signatures in Influenza A Viruses
Figure 10
Genomic signatures in PB1-F2: (a) avian vs. human (b) swine vs. human.
Green circles denote the signatures in the PB1-F2 sequence, with their positions shown on the bottom line. The dominant amino acid residues of the signatures are placed above (A to A or S to S) and under (H to H) the circles. The color lines indicate the functional or structural domains mapped by the signatures.
