Figure 3.

Codon usage plots of HAV compared with other viruses. The codon usage of HAV is compared with that of triatoma virus (a, b) for all variable codons (a) and for those amino acids with a frequency >4.5% in the HAV proteome (b). The codon usage of triatoma virus and its natural host are compared in panel (c). In panel (d), the comparison is extended to other virus species sharing codon usage with HAV. IAPV: Israeli acute paralysis virus. CrPV: Cricket paralysis virus. For more information on these other virus species see Table 1
