PEP, Posterior Error Probability; Coverage, The percent coverage calculated by dividing the number of amino acids in all found peptides by the total number of amino acids in the entire protein sequence; PSMs, Peptide Spectrum Matches; AAs, number of amino acids found in the protein; MW [kDa], Theoretical Molecular weight in kDa; Calc. pI, calculated isoelectric point; Score Sequest HT, Sum of the scores of the individual peptides from the Sequest HT search. P1, P2, P3, and P4 are the designation given to each identified protein.
