Lineage for Superfamily b.121.4: Positive stranded ssRNA viruses

  1. Root: SCOPe 2.06
  2. 2017114Class b: All beta proteins [48724] (177 folds)
  3. 2075417Fold b.121: Nucleoplasmin-like/VP (viral coat and capsid proteins) [88632] (7 superfamilies)
    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. 2075626Superfamily b.121.4: Positive stranded ssRNA viruses [88633] (10 families) (S)

Families:

  1. 2075627b.121.4.1: Picornaviridae-like VP (VP1, VP2, VP3 and VP4) [88634] (10 protein domains)
    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. 2075967b.121.4.2: Comoviridae-like VP [88636] (3 protein domains)
    duplication: mature coat protein consists of three similar domains that can be in a single chain or in two separate chains
  3. 2075995b.121.4.3: Caliciviridae-like VP [88637] (1 protein)
  4. 2076001b.121.4.4: Nodaviridae-like VP [88638] (1 protein)
  5. 2076015b.121.4.5: Bromoviridae-like VP [88639] (2 protein domains)
  6. 2076068b.121.4.6: Tymoviridae-like VP [88641] (2 protein domains)
    automatically mapped to Pfam PF00983
  7. 2076096b.121.4.7: Tombusviridae-like VP [88643] (5 protein domains)
  8. 2076140b.121.4.8: Tetraviridae-like VP [101568] (1 protein)
    automatically mapped to Pfam PF03566
  9. 2076147b.121.4.9: Birnaviridae-like VP [141109] (2 protein domains)
    dsRNA virus but unlike the other dsRNA viruses has a genomic arrangement and genomic replication strategy similar to +sRNA viruses; includes Pfam PF01766; Birnavirus VP2 protein
  10. 2076195b.121.4.0: automated matches [191569] (1 protein)
    not a true family
