How do I link to a specific version of a UniProtKB entry?
Last modified May 30, 2012
In order to keep up-to-date with scientific knowledge, we update entries thus producing a new version of the entry each time. For example, there have been over 150 updates to P00750 (TPA_HUMAN).
The version number appears below the accession number right at the top of a UniProtKB entry view. The History link allows you to browse and compare various versions of the entry.

To link to a particular version of an entry, use the version parameter in the link, e.g. to link to version 109 of P00750 use:
http://www.uniprot.org/uniprot/P00750.txt?version=109
