Description and Uses

Nitrotyrosine is formed by peroxynitrite-mediated nitration of protein tyrosine residues. Its presence on proteins can be used as a marker for peroxynitrite formation in vivo. Both free and protein-bound nitrotyrosine are commonly found in mammalian tissues and are increased in pathological conditions. The basal levels of free nitrotyrosine in human plasma is approximately 3 nM as determined by gas chromatography/mass spectrometry.

3-Nitro-L-tyrosine is used as an indicator of the formation of peroxynitrite by NO-dependent oxidative damage.
