CAPS-DB is a structural classification of helix-cappings or caps compiled from protein structures. The regions of the polypeptide chain immediately preceding or following an alpha-helix are known as Nt- and Ct cappings, respectively. Caps extracted from protein structures have been structurally classified based on geometry and conformation and organized in a tree-like hierarchical classification where the different levels correspond to different properties of the caps.

Pattern for CURIES

Compact URIs (CURIEs) constructed from CAPS-DB should match this regular expression:

Example CURIE

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

Registry Name Metaprefix External Prefix miriam caps
Name-to-Thing n2t caps
Prefix Commons prefixcommons CAPS

Providers are various services that resolve CURIEs to URLs. The example CURIE caps:434 is used to demonstrate the provides available for caps. Generation of OLS and BioPortal URLs requires additional programmatic logic beyond string formatting.
