The accession number was based on UniProt database. Description: the protein identified in the UniProt database. Score: ion score of the identified protein from the UniProt database. Coverage: sequence coverage calculated by dividing the number of matching amino acid residues by the total number of residues in the observed protein. Unique peptides: the number of sequences from the identified peptides that differed in at least 1 amino acid residue
AAs number of amino acids, MW molecular weight, pI isoelectric point
