Dissociation behavior of doubly-charged tryptic peptides: correlation of gas-phase cleavage abundance with ramachandran plots.
نویسندگان
چکیده
Analysis of fragmentation patterns from 5654 unique doubly charged tryptic peptides is obtained. Great variability of average relative abundance of bond cleavage is found between different amino acid combinations. There exist similarities as well as differences between b and y ions. Strong enhancement or suppression of cleavage gives insight into possible chemical interactions at reactive conformations formed by preferred phi-psi angles.

The influence of histidine on cleavage C-terminal to acidic residues in doubly protonated tryptic peptides
An ion-trap CID MS/MS spectral database of 505 doubly protonated tryptic peptides was used to investigate the influence of an internal basic residue on preferential fragmentation C-terminal to the acidic amino acid residues, aspartic acid (Asp) and glutamic acid (Glu). Because tryptic peptides, which contain C-terminal Lys or Arg, were selected for analysis, the majority of the peptides contain...
متن کاملStatistical characterization of ion trap tandem mass spectra from doubly charged tryptic peptides.
Collision-induced dissociation (CID) is a common ion activation technique used to energize mass-selected peptide ions during tandem mass spectrometry. Characteristic fragment ions form from the cleavage of amide bonds within a peptide undergoing CID, allowing the inference of its amino acid sequence. The statistical characterization of these fragment ions is essential for improving peptide iden...
متن کاملA mechanistic investigation of the enhanced cleavage at histidine in the gas-phase dissociation of protonated peptides.
Enhanced gas-phase cleavage of peptides adjacent to histidine was investigated. The peptides examined were angiotensins III (RVYIHPF) and IV (VYIHPF) as well as synthetic peptide analogues with altered key residues ((R)VYI-X-Z-F; X = F or H and Z = A, P, or Sar) or a fixed charge M3P(+)CH(2)C(O)-VYIHPF. While all singly protonated peptide ions containing both histidine and arginine fragment non...
متن کاملStatistical characterization of the charge state and residue dependence of low-energy CID peptide dissociation patterns.
Data mining was performed on 28 330 unique peptide tandem mass spectra for which sequences were assigned with high confidence. By dividing the spectra into different sets based on structural features and charge states of the corresponding peptides, chemical interactions involved in promoting specific cleavage patterns in gas-phase peptides were characterized. Pairwise fragmentation maps describ...
متن کاملComparison of the electron capture dissociation fragmentation behavior of doubly and triply protonated peptides from trypsin, Glu-C, and chymotrypsin digestion.
In bottom-up proteomics, proteolytically derived peptides from proteins of interest are analyzed to provide sequence information for protein identification and characterization. Electron capture dissociation (ECD), which provides more random cleavages compared to "slow heating" techniques such as collisional activation, can result in greater sequence coverage for peptides and proteins. Most bot...
