proteome/ — sources

Provenance lives in README.md beside this file, and is not repeated here: it carries every proteome's organism, UniProt proteome ID, taxid, sequence count and gzipped size, plus the exact fetch form (UniProt REST ?query=(proteome:<UPID>)&format=fasta, or the reference_proteomes FTP). All 19 files are experimental sequence, unmodified.

Summary: human.fasta.gz (UP000005640, 147,506 seqs) and mouse.fasta.gz (UP000000589, 54,857) are the full proteomes including isoforms and TrEMBL; the other 16 are canonical reference proteomes — 5 bacterial and 11 viral, 16,467 sequences in total — for molecular-mimicry scans and peptide-flank extraction.

Two traps the README records and that are easy to reintroduce:

  • UP000007639 is EBV strain AG876, not HHV-7, despite the adjacency of the IDs. The genuine HHV-7 reference is UP000098510 (strain RK, 84 proteins).
  • Two EBV strains are present on purpose (B95-8 and AG876); they are not duplicates.

Size is the operational fact. The human proteome has 68,389,335 nine-mer windows — every position of every protein, because a source lookup is a question about where — and one seqtree index over them costs ~12.6 GB. Ask for the lengths you need (mhcmatch.proteome.Proteome.find_sources builds one index per distinct query length).
