Partial spectrum of PSD fragment ions obtained from m/z 1479.76 precursor ion. Masses of N-terminal ion series of the b and a type [12] are in agreement with the modified sequence Acetyl-SSRYRVEYHK. His and Tyr immonium ions, as well as C-terminal ions (y type) confirm the sequence of the modified peptide.
