Re-examination of nepovirus polyprotein cleavage sites highlights the diverse specificities and evolutionary relationships of nepovirus 3C-like proteases [PDF]
Archives of Virology, 2022 AbstractPlant-infecting viruses of the genus Nepovirus (subfamily Comovirinae, family Secoviridae, order Picornavirales) are bipartite positive-strand RNA viruses with each genomic RNA encoding a single large polyprotein. The RNA1-encoded 3C-like protease cleaves the RNA1 polyprotein at five sites and the RNA2 polyprotein at two or three sites ...
