Luteovirus putative VPg genome linked protein
This family consists of several putative genome linked proteins. The genomic RNA of luteoviruses are linked to virally encoded genome proteins (VPg). Open reading frame 4 is thought to encode the VPg in Soybean dwarf luteovirus. Luteoviruses have isometric capsids that contain a positive stand ssRNA genome, they have no DNA stage during their replication.
