Class c: Alpha and beta proteins (a/b) [51349] (148 folds) 
Fold c.55: Ribonuclease H-like motif [53066] (7 superfamilies)
3 layers: a/b/a; mixed beta-sheet of 5 strands, order 32145; strand 2 is antiparallel to the restSuperfamily c.55.3: Ribonuclease H-like [53098] (16 families) 
consists of one domain of this fold
Family c.55.3.15: PIWI domain C-terminal [310608] (4 proteins)
PubMed 15565169 notes that both halves of PIWI are usually a single evolutionary unit; however, fragments have been characterized separately. The N-terminal half is (c.44.3.1)
