Extended Data Fig. 5: Analysis of environmental pesti-like viruses.

a, Large genome flavivirus/Pestivirus subset of the Flaviviridae phylogeny (Tree 18) collapsed to highlight the environmental pesti-like viruses for which no glycoproteins were identified. The scale bar denotes the number of amino acid substitutions per site. b, Genome organisation is provided for each species, with annotations based on conserved domain sequence searches. c, Foldseek e-value heatmaps for the indicated reference proteins, values are log transformed and colour-coded as shown in the key. For E, E1 and E2 the values represent summary e-values after comparison with a range of relevant reference structures, as described in the methods.
