EndoU-like
SCOP ID: 3000687
similarity to the RNase A-like superfamily (SCOP ID 3001918) 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)
