| SCOP superfamily ID | superfamiily description | corresponding fold description |
|---|---|---|
| d.185.1 | LuxS/MPP-like metallohydrolase Share the same "active site motif" HxxEH located in the first core helix, but differ in one of the zinc-binding residues ! | LuxS/MPP-like metallohydrolase core: beta-alpha-beta(2)-alpha(2); 2 layers: alpha/beta |
| d.15.2 | CAD & PB1 domains contain extra helix; similar heterodimerization modes; possibly related to the ubiquitin-like superfamily ! | beta-Grasp (ubiquitin-like) core: beta(2)-alpha-beta(2); mixed beta-sheet 2143 |
