Sequence-Scrambling Fragmentation Pathways of Protonated Peptides.

The gas-phase structures and fragmentation pathways of the N-terminal b and a fragments of YAGFL-NH, AGLFY-NH, GFLYA-NH, FLYAG-NH, and LYAGF-NH were investigated using collision-induced dissociation (CID) and detailed molecular mechanics and density functional theory (DFT) calculations. Our combined...
