Lineage for Superfamily c.8.7: RraA-like
- Root: SCOPe 2.01
Class c: Alpha and beta proteins (a/b) [51349] (147 folds) 
Fold c.8: The "swivelling" beta/beta/alpha domain [52008] (10 superfamilies)
3 layers: b/b/a; the central sheet is parallel, and the other one is antiparallel; there are some variations in topology
this domain is thought to be mobile in most multi-domain proteins known to contain it
Superfamily c.8.7: RraA-like [89562] (2 families) 
structural similarity and possible distant homology to the phosphohistidine domain of pyruvate phosphate dikinase
Families:
c.8.7.1: RraA-like [89563] (4 proteins)
aka MenG-like; characterized as regulator of RNase E activity A (RraA) that globally modulates RNA abundance in E. coli
c.8.7.0: automated matches [191574] (1 protein)
not a true family
