Description: Tyrosine as the most sensitive residue among the aromatic amino acid residues is the potential target of oxidative modification. Moreover, an oxidized product 1 , 3-dityrosine is formed through protein dimerization. Dityrosine is a highly fluorescent compound that is resistant to protease activity and acid hydrolysis. Furthermore, dityrosine is a useful marker for assessing oxidative damage to proteins, which can be generated during a normal physiological process in specialized cases and also as a result of exposure to environmental agents (ultraviolet irradiation, radicals, NO2, and lipid hydroperoxides). Dityrosine has been found in the elastic ligaments of insects , the cell walls of Candida albicans and Saccharomyces cerevisiae, and the fertilization envelope of the sea urchin egg Stronglycocentrotus purpuratus. Additionally, dityrosine has been detected in the hydrolysates of some structural proteins, insoluble proteins derived from human cataractous lenses, elastin, collagen, and the storage form of thyroglobulin. In addition, dityrosine is also linked to a number of serious pathological cases, such as brain tissues from Parkinson’s disease, and aortic tissues of hyperglycaemic animals.
