Resonant neutral particle emissions at the energies of 6–7 eV were observed, as well as a rise towards zero-energy, which are typical electron-capture dissociation profiles. The presence of disulfide (S–S) bonds tends to enhance the resonant bump heights. Chemical nature of the amino-acid residues adjacent to cysteines appears to correlate with the bump strength. Molecular-dynamical simulations help clarify the role of molecular vibration modes in the electron-capture dissociation process.}, pages = {83--87}, title = {Resonant neutral particle emission in collisions of electrons with protonated peptides with disulfide bonds at high energies}, volume = {504}, year = {2011} }
