It has recently been shown that tyrosyl radicals react with superoxide to form a peroxide adduct of tyrosine. Since myeloperoxidase oxidizes tyrosine to its radical, and neutrophils and monocytes contain myeloperoxidase as well as produce superoxide, we have investigated whether tyrosine peroxide could be a significant product of tyrosine oxidation by these cells. Oxidation of tyrosine by purified myeloperoxidase and a superoxide-generating system, and by stimulated human neutrophils, was found… CONTINUE READING
