Table 3 List of peptides that are characteristic of the Bovinae subfamily, with indication of their position in the corresponding proteins, mass to charge ratio (m/z), charge (z), measurement error (Δm), identification score (reported as -10lgP, i.e. converted P value; higher numbers indicate higher-confidence matches), retention time (RT), and animal species that contain that specific peptide. Deamidation variants of these peptides are not referenced in the table. Lower case letters in peptide sequences indicate the following modifications: n asparagine deamidation, m methionine oxidation, s serine phosphorylation, c cysteine carbamidomethylation (induced by sample treatment), w tryptophan oxidation, q glutamine deamidation or N-terminal glutamate conversion to pyroglutamate
