The post-translational modifications used in the UniProt knowledgebase (Swiss-Prot and TrEMBL). The definition of the post-translational modifications usage as well as other information is provided in the following format
uniprot.ptm
Local identifiers in UniProt Post-Translational Modification should match this
regular expression:
^PTM-\d{4}$
Compact URIs (CURIEs) constructed from UniProt Post-Translational Modification should match
this regular expression:
^uniprot\.ptm:PTM-\d{4}$
A provider turns a local unique identifiers from a resource into a URI. Many providers are also resolvable as URLs (i.e., they can be used in a web browser).
The local unique identifier PTM-0450
is used to demonstrate the providers
available for UniProt Post-Translational Modification. Some providers may use a different example, which is displayed in the table below.
A guide for curating additional providers can be found
here.
