摘要
The fragmentation pathways of different conformations of three charge states of ubiquitin ions are examined using ion mobility/collisional activation/time-of-flight techniques. Mass spectra for fragments for different conformers of a single charge state appear to be identical (within the experimental reproducibility). These results are consistent with a mechanism in which different conformers of each charge state rearrange to similar dissociation transition states prior to fragment formation.
