Fold: Rhodanese/Cell cycle control phosphatase

3 layers: a/b/a; parallel beta-sheet of 5 strands, order 32451

Lineage:

1. Root: scop
2. Class: Alpha and beta proteins (a/b)
   Mainly parallel beta sheets (beta-alpha-beta units)
3. Fold: Rhodanese/Cell cycle control phosphatase
   3 layers: a/b/a; parallel beta-sheet of 5 strands, order 32451

Superfamilies:

1. Rhodanese/Cell cycle control phosphatase (2)
   the active site structure is similar to those of the families I and II protein phosphatases; the topology can be related by a different circular permutation to the family I topology
   1. Cell cycle control phosphatase, catalytic domain (2)
   2. Sulfurtransferase (rhodanese) (2)
      duplication, consists of two domains of this fold
