Identification and Chronological Analysis of Genomic Signatures in Influenza A Viruses
Figure 2
Genomic signatures in PB2: (a) avian vs. human (b) swine vs. human.
Green circles denote the signatures in the PB2 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.
