Fold: The "swivelling" beta/beta/alpha domain

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

Lineage:

  1. Root: scop
  2. Class: Alpha and beta proteins (a/b) [51349]

  3. Fold: The "swivelling" beta/beta/alpha domain [52008]
    3 layers: b/b/a; the central sheet is parallel, and the other one is antiparallel; there are some variations in topology
