Lineage for Fold c.8: The "swivelling" beta/beta/alpha domain
- Root: SCOP 1.65
Class c: Alpha and beta proteins (a/b) [51349] (121 folds) 
Fold c.8: The "swivelling" beta/beta/alpha domain [52008] (7 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 all proteins known to contain it
Superfamilies:
c.8.1: Phosphohistidine domain [52009] (2 families) 
contains barrel, closed, n=7, S=10
c.8.2: Aconitase [52016] (1 family)
contains mixed beta-sheet barrel, closed n=7, S=10
c.8.3: Carbamoyl phosphate synthetase, small subunit N-terminal domain [52021] (1 family) 
c.8.4: Transferrin receptor ectodomain, apical domain [52025] (1 family) c.8.5: GroEL apical domain-like [52029] (2 families) 
c.8.6: Swiveling domain of the glycerol dehydratase reactivase alpha subunit [82317] (1 family) 
c.8.7: RraA-like [89562] (1 family)
structural similarity and possible distant homology to the phosphohistidine domain of pyruvate phosphate dikinase
