Fund Project: The authors would like to thank the financial support from the National Natural Science Foundation of China (No. 20320130046) and the Specialized Research Fund for the Doctoral Program of Higher Education (SRFDP) of MOE (No. 20030003049).

Hydroxylation of 3-nitrotyrosine (3-NT) and 3-NT containing peptide Gly-nitroTyr-Gly in aqueous solution by hydroxyl radical were investigated with gamma irradiation. The structures of the hydroxylated products were confirmed by electrospray ionization mass spectrometry and ¹H NMR spectrometry. The reactivity of 3-nitrotyrosine has been investigated using density functional theory (DFr) calculation.
