The Catalytic Site Atlas (CSA) is a database documenting enzyme active sites and catalytic residues in enzymes of 3D structure. It uses a defined classification for catalytic residues which includes only those residues thought to be directly involved in some aspect of the reaction catalysed by an enzyme.

Pattern for Local Unique Identifiers

Local identifiers in Catalytic Site Atlas should match this regular expression:
^[0-9][A-Za-z0-9]{3}$

Example Local Unique Identifier
1a05   Resolve
Pattern for CURIES

Compact URIs (CURIEs) constructed from Catalytic Site Atlas should match this regular expression:
^csa:[0-9][A-Za-z0-9]{3}$

Example CURIE
csa:1a05
Metaregistry

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

Registry Name Metaprefix External Prefix
Identifiers.org miriam csa
Name-to-Thing n2t csa
Prefix Commons prefixcommons CSA
Providers

Providers are various services that resolve CURIEs to URLs. The example CURIE csa:1a05 is used to demonstrate the provides available for csa. Generation of OLS and BioPortal URLs requires additional programmatic logic beyond string formatting.
