Aromatic side chains on amino acids influence the fragmentations of cationic complexes of doubly charged metal ions and singly deprotonated peptides. The metal ion interacts with an aromatic side chain and binds to adjacent amide nitrogens. When fragmentation occurs, this bonding leads to the formation of abundant metal-containing a-type ions by reactions that occur at the sites of amino acids that contain the aromatic side chain. Furthermore, formation of metal-containing immonium ions of the amino acids that contain the aromatic side chain also are formed. The abundant a-type ions may be useful in interpretation strategies in which it is necessary to locate in a peptide the position of an amino acid that bears an aromatic side chain.
