Characteristics of identified and unidentified mutable PSMs. a PSMs separated by evolutionary distance, here indicated as the number of amino acid differences (SAPs) between the homologous Homo and Pan or Pongo peptide sequence. Mutable PSMs are mostly identified when one amino acid position differs between the sequence represented by the MS/MS spectrum and the provided sequence database. b Proportion of unidentified mutable PSMs by PSM length. Longer mutable PSMs are frequently unidentified in the Pan and Pongo searches. Fitted logistic curve with 1SD. PSMs with a length of < 10 amino acids were excluded from analysis
