SCOPe 2.06: Family b.121.4.2: Comoviridae-like VP

Lineage for Family b.121.4.2: Comoviridae-like VP

1. Root: SCOPe 2.06

2. Class b: All beta proteins [48724] (177 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.121.4.2: Comoviridae-like VP [88636] (3 proteins)
   duplication: mature coat protein consists of three similar domains that can be in a single chain or in two separate chains

Proteins:

1. Comovirus coat proteins (VP37 and VP23) [49627] (2 species)
   chain 1 is one-domain VP23; chain 2 is two-domain VP37

   1. Species BPMV (Bean pod mottle virus) [TaxId:12260] [49628] (3 PDB entries)

   2. Species CPMV (Cowpea mosaic virus) [TaxId:12264] [89227] (2 PDB entries)

2. Nepovirus capsid protein [49629] (1 species)
   duplication: cnosists of three very similar domains

   • Species TRSV (Tobacco ringspot virus) [TaxId:12282] [49630] (1 PDB entry)

3. automated matches [310893] (1 species)
   not a true protein

   • Species CPMV (Cowpea mosaic virus) [TaxId:12264] [311486] (2 PDB entries)
