| SCOP superfamily ID | superfamiily description | corresponding fold description |
|---|---|---|
| c.8.4 | PA domain | 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 |
| c.83.1 | Aconitase iron-sulfur domain | Aconitase iron-sulfur domain consists of three similar domains with 3 layers (a/b/a) each; duplication ! core: parallel beta-sheet of 5 strands, order 32145 |
