The collision-induced spectra of [M-H] -ions of peptides containing Asp and Asn residues exhibit characteristic backbone cleavage ions produced via the enolate anions of the Asp or Asn side chains. Such reactions do not occur from the analogous Glu or Gln residues. Asp and Asn residues may be distin
