The directory contains files describing various features of S. pombe proteins: 

- aa_composition.tsv describes the aminoacid composition,
  in number of residues, of all S. pombe proteins.

- disordered_regions.tsv lists the disordered regions 
  and their coordinates in all S. pombe proteins.

- peptide_stats.tsv lists the protein properties that can be found
  in the "Protein domains and properties" section of the gene pages
  on PomBase: predicted molecular weight (kDa), predicted isoelectric point, 
  charge at pH7, length ("Residues") and codon adaptation index (CAI).

- protein_families_and_domains.tsv describes protein features such as domains and 
  family assignments that can be visualized in the "Protein domains and properties" 
  section of the gene pages on PomBase. For more informations,  
  see https://www.pombase.org/documentation/gene-page-protein-features

- protein_modifications.tsv lists all the protein modifications annotations
  currently featured in PomBase. See https://www.pombase.org/documentation/gene-page-modifications
  for a detailed description of the "Modifications" section of the gene pages.
