Extracting both peptide sequence and glycan structural information by 157 nm photodissociation of N-linked glycopeptides.


The 157 nm photodissociation of N-linked glycopeptides was investigated in MALDI tandem time-of-flight (TOF) and linear ion trap mass spectrometers. Singly charged glycopeptides yielded abundant peptide and glycan fragments. The peptide fragments included a series of x-, y-, v-, and w- ions with the glycan remaining intact. These provide information about… (More)
