Lineage for Species: Infectious bursal disease virus [TaxId: 10995]

1. Root: SCOPe 2.05

2. Class b: All beta proteins [48724] (176 folds)

3. Fold 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. Superfamily b.121.4: Positive stranded ssRNA viruses [88633] (10 families)

5. Family b.121.4.9: Birnaviridae-like VP [141109] (2 proteins) 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

6. Protein Birnavirus VP2 [141110] (1 species) Link between +sRNA and dsRNA viruses two domains - the first similar to (88633) and the second, insert domain is similar to (49818). dsRNA virus but unlike the other dsRNA viruses has a genomic arrangement and genomic replication strategy similar to +sRNA viruses
