Virulence factor of potato virus Y, genome-attached terminal protein VPg, is a highly disordered protein.

Abstract

Potato virus Y (PVY) is a common potyvirus of agricultural importance, belonging to the picornavirus superfamily of RNA plus-stranded viruses. A covalently linked virus-encoded protein VPg required for virus infectivity is situated at the 5' end of potyvirus RNA. VPg seems to be involved in multiple interactions, both with other viral products and host… (More)
