ArchDB is a compilation of structural classifications of loops extracted from known protein structures. The structural classification is based on the geometry and conformation of the loop. The geometry is defined by four internal variables and the type of regular flanking secondary structures, resulting in 10 different loop types. Loops in ArchDB have been classified using an improved version (Espadaler et al.) of the original ArchType program published in 1997 by Oliva et al.
The metaregistry provides mappings between the Bioregistry and other registries. There are 3 mappings to external registries for this resource with 3 unique external prefixes.
Providers are various services that resolve CURIEs to URLs. The example CURIE
is used to demonstrate the provides available for
this resource. Generation of OLS and BioPortal URLs requires additional programmatic
logic beyond string formatting.
