A kinetic study on the interaction of deprotonated purine radical cations with amino acids and model peptides

By use of pulse radiolysis techniques, the radical cations of purine nucleotides have been successfully produced by the SO 4 − ion oxidation. Time-resolved spectroscopic evidence is provided that the one-electron-oxidized radicals of dAMP and dGMP can be efficiently repaired by aromatic amino acids...
