12361810-3	2002	While NO(2)Tyr has been considered a marker of peroxynitrite (ONOO(-)) formation previously, there is growing evidence that heme-protein peroxidase activity, in particular neutrophil-derived myeloperoxidase (MPO), significantly contributes to NO(2)Tyr formation in vivo via the oxidation of nitrite (NO(2)(-)) to nitrogen dioxide (.NO(2)).
