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 superfamily classification.
The metaregistry provides mappings between the Bioregistry and other registries. There are
3 mappings to external registries for
Providers are various services that resolve CURIEs to URLs. The example CURIE
cath.superfamily:18.104.22.168 is used to demonstrate the provides available for
cath.superfamily. Generation of OLS and BioPortal URLs requires additional programmatic
logic beyond string formatting.
