3Dee contains structural domain definitions for all protein chains in the Protein Databank (PDB), currated by the EBI and the RCSB, that have 20 or more residues and are not theoretical models. These structures are listed here. These domains have been clustered by both sequence and structural similarity. The resulting families are stored in a hierarchy. A more detailed introduction on the 3Dee database can be found here.
