Unimod is a public domain database created to provide a community supported, comprehensive database of protein modifications for mass spectrometry applications. That is, accurate and verifiable values, derived from elemental compositions, for the mass differences introduced by all types of natural and artificial modifications. Other important information includes any mass change, (neutral loss), that occurs during MS/MS analysis, and site specificity, (which residues are susceptible to modification and any constraints on the position of the modification within the protein or peptide).

The metaregistry provides mappings between the Bioregistry and other registries. There are 6 mappings to external registries for this resource with 3 unique external prefixes.

Providers are various services that resolve CURIEs to URLs. The example CURIE unimod:1200 is used to demonstrate the provides available for this resource. Generation of OLS and BioPortal URLs requires additional programmatic logic beyond string formatting.
