| Structures in the PDB repository are of varying quality. In order to maintain accuracy when classifying and clustering protein domains, it is important only to include high quality structures. For this reason we have defined a strict set of criteria, called SIFT, to state whether or not a PDB chain can be accepted into CATH. | Structures in the PDB repository are of varying quality.
