Energetic switch of the proline effect in collision‐induced dissociation of singly and doubly protonated peptide Ala‐Ala‐Arg‐Pro‐Ala‐Ala

Energetic switch of the proline effect in collision‐induced dissociation of singly and doubly protonated peptide Ala‐Ala‐Arg‐Pro‐Ala‐Ala

D Huo, T Qin, L Zu - Journal of Mass Spectrometry, 2019 - Wiley Online Library

Suppression of the selective cleavage at N‐terminal of proline is observed in the peptide 
cleavage by proteolytic enzyme trypsin and in the fragment ion mass spectra of peptides
containing Arg‐Pro sequence. An insight into the fragmentation mechanism of the influence …
