Secondary fragmentations of three synthetic peptides (human alphaA crystallin peptide 1-11, the deamidated form of human betaB2 crystallin peptide 4-14, and amyloid beta peptide 25-35) were studied in both electron capture dissociation (ECD) and electron-transfer dissociation (ETD) mode. In ECD, in addition to c and z. ion formations, charge remote fragmentations (CRF) of z. ions were abundant, resulting in internal fragment formation or partial/entire side-chain losses from amino acids, sometim ...[more]
