SO2-* electron transfer ion/ion reactions with disulfide linked polypeptide ions.
Multiply-charged peptide cations comprised of two polypeptide chains (designated A and B) bound via a disulfide linkage have been reacted with SO2-* in an electrodynamic ion trap mass spectrometer. These reactions proceed through both proton transfer (without dissociation) and electron transfer (with and without dissociation). Electron transfer reactions are shown to give rise to cleavage along...
متن کاملReactions of polypeptide ions with electrons in the gas phase.
Reactions of electrons in the energy range below 70 eV with polypeptide cations and anions are reviewed, as well as their applications for the structural analysis of polypeptides. At very low energies (</= 0.1 eV), the major outcome is electron-capture dissociation (ECD) of S-S and backbone N-C(alpha) bonds, leading to c' and z. fragments. ECD is useful in sequencing and characterization of pos...
متن کاملBiological electron-transfer reactions.
A wide range of biological processes makes extensive use of electron-transfer reactions. Rigorous characterization of a biological electron-transfer reaction requires a combination of kinetic, thermodynamic, structural and theoretical methods. The rate of electron transfer from an electron donor to an electron acceptor through a protein is dependent on the difference in reduction potential of t...
متن کاملElectron transfer reactions in biological systems: the reduction of ferricytochrome c by chromous ions.
Chromous ion reacts with ferricytochrome c to yield a one-to-one Cr(III)-ferrocytochrome c complex. This material, when hydrolyzed by trypsin and subjected to chromatographic procedures, yielded two fragments containing chromium. The amino-acid compositions and chemical characteristics of each of these fragments indicated that the chromium had crosslinked two segments of polypeptide chain; thes...
متن کاملVisible light initiated release of calcium ions through photochemical electron transfer reactions.
Photolysis of anthraquinone or flavin photosensitizers in the presence of calcium EDTA complexes results in decomposition of the EDTA complex, releasing free Ca2+. In the case of the flavin sensitizers, it is shown that millimolar concentrations of Ca2+ can be released using visible light (>440 nm) and with quantum yields as high as 0.31. The utility of this system is further demonstrated by in...
