Sliding window overview of the amino acid composition of all Jeilongvirus G proteins. The used window size for each protein is 10% of the respective protein length. The dotted red line represents the average length of paramyxovirus G proteins. All Jeilongvirus G proteins are marked by the presence of an otherwise absent C-terminal region, marked by a high, yet variable abundance of P/T/S (up to 50%). In the genomes of JPV, BeiPV and TlmPV, the G gene is divided into two ORFs, G and X. A single mutation/insertion, however, suffices to join these two ORFs into a single ORF covering the entire G gene. The P/T/S fraction of the resulting hypothetical BeiPV and TlmPV G proteins (yellow/orange dashed lines) is similar to those of the Rodent PV and PMPV-1 G proteins. For JPV, which is more closely related to MMLPV-1/2 (Fig. 2, Additional file 1: Figure S1), this effect is less pronounced, although a narrow peak in P/T/S-abundance, similar to the MMLPV-2 peak, can be observed in the resulting hypothetical JPV G protein (dashed red line)
