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.
The metaregistry provides mappings between the Bioregistry and other registries. There are

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.
