Comprehensive Analysis of Gly-Leu-Gly-Gly-Lys Peptide Dication Structures and Cation-Radical Dissociations Following Electron Transfer: From Electron Attachment to Backbone Cleavage, Ion-Molecule Complexes, and Fragment Separation Robert Pepin, Kenneth J. Laszlo, Bo Peng, Aleš Marek, Matthew F. Bush, František Tureček. J. Phys. Chem. A 2014, 118, 308–324. (Link|PUBMED)

Experimental data from ion mobility measurements and electron transfer dissociation were combined with extensive computational analysis of ion structures and dissociation energetics for Gly-Leu-Gly-Gly-Lys cations and cation radicals. Experimental and computational collision cross sections of (GLGGK + 2H)2+ ions pointed to a dominant folding motif that is represented in all low free-energy structures. The local folding motifs were Continue reading “New Publication: Comprehensive Analysis of Gly-Leu-Gly-Gly-Lys Peptide Dication Structures and Cation-Radical Dissociations Following Electron Transfer”
