UVPD mass spectra of singly deprotonated peptides: (A) sulfated leu-enkephalin and (B) phosphorylated P60c-src substrate II Ac-IpYGEF-NH2 using 3 laser pulses at 2 mJ. (C) Average percentage of the neutral loss product observed from the selected precursor and charge reduced precursor ions. Cionin is excluded from the sulfated peptide averages.
