Figure 1

General evolutionary trends of the Influenza A M2 Channel over three epochs. Frequencies of each amino acid occuring in more than 1% of strains are shown for the three epochs: previous century, past decade, and current decade. This table does not filter out specific host organisms; they are all considered together. Colors are assigned according to amino acid frequency; if the percentage of occurrences for an amino acid within the entire set is between two of the frequency cutoffs (specified in the legend below), it is assigned the color associated with the lower cutoff.
