Is there any way to batch download UniProt proteomes based on a list of proteome IDs (e.g. UP000011712).

I have a list of about 1,000 proteome IDs from UniProt. I know it is possible to do this with taxon IDs but I do not have these.

So, is it possible to batch download proteomes based on proteome IDs, or is there any way to convert proteome ID to taxon identifier?

Thanks for any help.
You can do this programmatically using URLs like
https://www.uniprot.org/uniprot/?query=proteome:UP000005640&format=fasta (FASTA format)

Use format=txt, format=xml etc for other download formats.

There is a related FAQ for programmatic access with a code example to download the UniProt reference proteomes for all organisms below a given taxonomy node in compressed FASTA format: https://www.uniprot.org/help/api_downloading
