Selective collision-induced fragmentation of ortho-hydroxybenzyl-aminated lysyl-containing tryptic peptides.
RATIONALE In protein studies that employ tandem mass spectrometry the manipulation of protonated peptide fragmentation through exclusive dissociation pathways may be preferred in some applications over the comprehensive amide backbone fragmentation that is typically observed. In this study, we characterized the selective cleavage of the side-chain Cζ-Nε bond of peptides with ortho-hydroxybenzyl...
متن کاملSubstituent effects on the gas-phase fragmentation reactions of protonated peptides containing benzylamine-derivatized lysyl residues.
Motivated by the need for chemical strategies designed to tune peptide fragmentation to selective cleavage reactions, benzyl ring substituent influence on the relative formation of carbocation elimination (CCE) products from peptides with benzylamine-derivatized lysyl residues has been examined using collision-induced dissociation (CID) tandem mass spectrometry. Unsubstituted benzylamine-deriva...
متن کامل1764 Identification of Tryptic Peptides
Several type C RNA-transforming viruses have been shown to contain acquired cellular sequences within preexisting viral genes (I-3). In many instances expression of proteins encoded by such sequences occurs by inphase read through of translation initiated at the 5' terminus of the viral genome. Resulting polyprotein translational products contain type C viral gag gene amino terminal structural ...
متن کاملShattering transitions in collision-induced fragmentation.
We investigate the kinetics of nonlinear collision-induced fragmentation. We obtain the fragment mass distribution analytically by utilizing its traveling wave behavior. The system undergoes a shattering transition in which a finite fraction of the mass is lost to infinitesimal fragments (dust). The nature of the shattering transition depends on the fragmentation process. When the larger of the...
متن کاملUnimolecular thermal fragmentation of ortho-benzyne.
The ortho-benzyne diradical, o-C(6)H(4) has been produced with a supersonic nozzle and its subsequent thermal decomposition has been studied. As the temperature of the nozzle is increased, the benzyne molecule fragments: o-C(6)H(4)+Delta--> products. The thermal dissociation products were identified by three experimental methods: (i) time-of-flight photoionization mass spectrometry, (ii) matrix...
