Lineage for Species: Murine hepatitis virus, MHV [TaxId: 11138]

1. Root: SCOPe 2.08

2. Class d: Alpha and beta proteins (a+b) [53931] (396 folds)

3. Fold d.294: EndoU-like [142876] (1 superfamily) comprises several helices and two three-stranded antiparallel beta-sheets; similar architecture to the RNase A-like fold (54075)

4. Superfamily d.294.1: EndoU-like [142877] (3 families) similarity to the RNase A-like superfamily (54076) extends to the active site location and architecture; the two structural cores of the RNase A and EndoU superfamilies are interrelated by a topological permutation - transposition of two pereferial beta-strands, suggesting possible distant homology of the two superfamilies (and their unification in a hyperfamily)

5. Family d.294.1.2: Nsp15 C-terminal domain-like [142881] (2 proteins) PfamB PB001946

6. Protein Nsp15, C-terminal domain [142882] (2 species)

7. Species Murine hepatitis virus, MHV [TaxId:11138] [142884] (2 PDB entries) Uniprot P16342 6720-6872
