Calculated boundaries for viral IDRs and highest proline density.

ID shows GenBank accession numbers for sequences used in the IDR calculation (DISOPRED2 [25]) and the polyproline sliding-window analysis. Class codes to right of each ID are: Av, avian; Ra, rat; genotype 1; genotype 2; subgenotype 3b; subgenotype 3f; genotype 4; WB, Japanese wild boar; Rub, rubivirus and CTV, cutthroat trout virus. The start and stop positions are those obtained from each calculation. Max is the maximum disorder probability in the PPR (threshold = 0.05). Pro lists the number of prolines in each PPR IDR. Avg P is the average number of prolines in all members of a class. Empty avg P indicates presence of only a single member in that class.
