A novel fragmentation of metastable peptide [M + H]+ ions is described. Loss of the Cterminal amino acid residue is accomqanied by retention of one of the carboxyl oxygens, as judged by '\*O-labeling. The retained 8O label is located at the new C-terminus. Sequential mass spectrometric analyses indi
