Programmatic access - Downloading data at every UniProt release

The HTTP header Last-Modified: will avoid that you download data more than once per release, if you use a download tool that makes use of this information, e.g. the unix commands lwp-mirror or curl with the -z option. Here are examples of how to do this in Perl:

  • Download all UniProt sequences for a given organism in FASTA format
  • Download the UniProt reference proteomes for all organisms below a given taxonomy node in compressed FASTA format

Release number and date

If you would like to record the UniProt release number and/or date of the data which you retrieve, you can extract this information from the HTTP header of the response (see this Perl example):

  • X-UniProt-Release: contains the UniProt release number, e.g. 2010_08
  • Last-Modified: contains the UniProt release date, e.g. Tue, 13 Jul 2010 00:00:00 GMT
