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

The metaregistry provides mappings between the Bioregistry and other registries. There are 3 mappings to external registries for cath.domain.

Registry Name Metaprefix External Prefix
Identifiers.org miriam cath.domain
Name-to-Thing n2t cath.domain
Prefix Commons prefixcommons CATH.DOMAIN
Providers

Providers are various services that resolve CURIEs to URLs. The example CURIE cath.domain:1cukA01 is used to demonstrate the provides available for cath.domain. Generation of OLS and BioPortal URLs requires additional programmatic logic beyond string formatting.
