Protein tyrosine nitration is a prevalent post-translational modification which occurs as a
result of oxidative and nitrative stress, it may be directly involved in the onset and/or
progression of diseases. Considering the existence of nano titanium dioxide (TiO2) in
environment and sunscreen products along with the high content of nitrite in sweat, the UV-
exposed skin may be a significant target for the photosensitized damage. In this paper,
tyrosine nitration of bovine serum albumin (BSA) was initiated in the UV-irradiated reaction …
