Superfamily: EndoU-like

similarity to the RNase A-like superfamily (scop_sf 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)

Lineage:

1. Root: scop
2. Class: Alpha and beta proteins (a+b) [53931]
   Mainly antiparallel beta sheets (segregated alpha and beta regions)
3. Fold: EndoU-like [142876]
   comprises several helices and two three-stranded antiparallel beta-sheets; similar architecture to the RNase A-like fold (scop_cf 54075)
4. Superfamily: EndoU-like [142877]
