The CATH database is a hierarchical domain classification of protein structures in the Protein Data Bank. Protein structures are classified using a combination of automated and manual procedures. There are four major levels in this hierarchy; Class (secondary structure classification, e.g. mostly alpha), Architecture (classification based on overall shape), Topology (fold family) and Homologous superfamily (protein domains which are thought to share a common ancestor). This colelction is concerned with CATH domains.

Pattern for Local Unique Identifiers

Local identifiers in CATH domain should match this regular expression:
^\w+$

Example Local Unique Identifier
1cukA01   Resolve
Pattern for CURIES

Compact URIs (CURIEs) constructed from CATH domain should match this regular expression:
^cath\.domain:\w+$

Example CURIE
cath.domain:1cukA01
Metaregistry CATH domain

The metaregistry provides mappings between the Bioregistry and other registries. There are 4 mappings to external registries for this resource with 2 unique external prefixes.

Providers

A provider turns a local unique identifiers from a resource into a URI. Many providers are also resolvable as URLs (i.e., they can be used in a web browser).

The local unique identifier 1cukA01 is used to demonstrate the providers available for CATH domain. A guide for curating additional providers can be found here.
