Superfamily: Positive stranded ssRNA viruses

link to SUPERFAMILY database - Superfamily

Lineage:

  1. Root: scop
  2. Class: All beta proteins [48724]
  3. Fold: Nucleoplasmin-like/VP (viral coat and capsid proteins) [88632]
    sandwich; 8 strands in 2 sheets; jelly-roll; some members can have additional 1-2 strands
    characteristic interaction between the domains of this fold allows the formation of five-fold and pseudo six-fold assemblies
  4. Superfamily: Positive stranded ssRNA viruses [88633]
    link to SUPERFAMILY database - Superfamily

Families:

  1. Picornaviridae-like VP (VP1, VP2, VP3 and VP4) [88634] (18) picpic
    the order of the chains N-VP0-VP3-VP1-C is as in the polyprotein; VP0 is cleaved later upon capsid assembly to VP4 and VP2
    there is a different order in the shuffled genome of insect picorna-like proteins (Cricket paralysis virus)
  2. Comoviridae-like VP [88636] (3) picpic
    duplication: mature coat protein consists of three similar domains that can be in a single chain or in two separate chains
  3. Caliciviridae-like VP [88637] (1) picpic
  4. Nodaviridae-like VP [88638] (3) picpic
  5. Tetraviridae-like VP [101568] (1) picpic
  6. Bromoviridae-like VP [88639] (4) picpic
  7. Tymoviridae-like VP [88641] (3) picpic
  8. Tombusviridae-like VP [88643] (7) picpic
  9. Birnaviridae-like VP [141109] (1) picpic
    dsRNA virus but unlike the other dsRNA viruses has a genomic arrangement and genomic replication strategy similar to +sRNA viruses; includes Pfam 01766; Birnavirus VP2 protein
