I'm trying to map the presence of three different proteins over the bacterial kingdom. First I thought of using pfam for this purpose, but two proteins end up in very messy DUFs (Domein of Unknown Function). So I now ran three BLAST queries on the Representative Proteomes ( and put an e-value threshold of 10-5 in place. 
This results for each protein in a BLAST table that contains both an UniProt Proteome Identifier and a NCBI Taxonomy identifiers. 
Now I want to map back these BLAST results to either a Uniprot taxonomy or NCBI taxonomy. For the NCBI taxonomy there is a tool available however does a similar taxonomy tool exist for the Uniprot as well? Preferably I would supply it with a list of Uniprot Proteome identifiers and it would return a tree (in for example) phylip format. This could then be visualized using iTOL. I found a neat translation between Uniprot and the NCBI taxonomy ( but I was wondering if a Uniprot taxonomy exist as well?

I suggest to add the tag "uniprot" in order to make this thread more easily findable.

In reply to your last question:

The taxonomy database that is maintained by the UniProt group (  is based on the NCBI taxonomy database, which is supplemented with data specific to the UniProt Knowledgebase (UniProtKB). While the NCBI taxonomy is updated daily to be in sync with GenBank/EMBL-Bank/DDBJ, the UniProt taxonomy is updated only at UniProt releases to be in sync with UniProtKB. It may therefore happen that for the time period of a UniProt release, you can find new taxa at the NCBI that are not yet in UniProt (and vice versa for deleted taxa).

For more details see


Regarding a mapping of proteome identifiers to tax_ids, you can query the "Proteomes" section of the UniProt website and then download the results in tab-delimited format, e.g. for non-redundant bacterial proteomes (limited to the first 10 hits):[2]%22%20redundant:no&fil=&limit=10&force=no&preview=true&format=tab&columns=id,organism-id
