Proline as a charge stabilizing amino acid in peptide radical cations

Monney, Nicolas P.-A. ; Bally, Thomas ; Giese, Bernd

In: Journal of Physical Organic Chemistry, 2015, vol. 28, no. 5, p. 347–353

Long distance electron transfer in proteins requires relay stations that can be transitorily oxidized or reduced. Although individual prolines cannot assume this function, because of their high ionization energy, it has been shown that polyprolines have the ability to transfer charges. In order to determine the role of the proline in the hole distribution and transport within a PheProPhe...
