Spectrum obtained from two peptides derived from ANXA1 that contain the same cysteine group. (A) The peptide was detected with mass-to-charge ratio 928.8691. The tandem mass spectrum matched the following sequence, CEDMSVNQDLADTDAR, indicating that the Cys was modified (+74); the detection of b2 is consistent with this localization. The assignment was made with Sequest with XCorr 3.30 and ΔCN 0.45 (B) The peptide was detected with mass-to-charge ratio 728.6382. The tandem mass spectrum matched the following sequence, GDRCEDMSVNQDLADTDAR, indicating that the Cys was modified (+74); the detection of b5 is consistent with this localization. The assignment was made with Sequest with XCorr 4.62 and ΔCN 0.43.
