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)
Superfamilies:
EndoU-like [142877] (2) 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) uperfamily
