Sequence database setup: UniProt proteomes

A UniProt complete proteome consists of the set of proteins thought to be expressed by an organism whose genome has been completely sequenced. A reference proteome is the complete proteome of a representative, well-studied model organism or an organism of interest for biomedical research.

UniProtKB is a collaboration between the European Bioinformatics Institute, the Swiss Institute of Bioinformatics and the Protein Information Resource.

Proteome ID

First, you need to discover the Proteome ID for your proteome of interest by searching https://www.uniprot.org/proteomes/. This example uses rice, taxonomy Oryza sativa subsp. japonica with Proteome ID UP000059680.

Create the database

In Database Manager, create a new custom definition, as follows:

  1. FASTA, New database; Create New
  2. Use pre-defined template; UniProt_proteome_template
  3. Next, Create
  4. Download from remote URL; Next
  5. Set up download URL
  6. Paste the following into the FASTA file URL field, where the proteome ID is for your proteome of interest
    https://rest.uniprot.org/uniprotkb/stream?query=proteome:UP000059680&format=fasta&compressed=false&includeIsoform=true
  7. Save; Start downloading
  8. Activate

Once configured, you can enable automatic updating by clicking on the database name then choosing Edit schedule.
