Peroxynitrous Acid 229-242 superoxide dismutase 3 Homo sapiens 27-30 9484979-11 1998 High EC-SOD expression in the arterial wall may be required not only to prevent deleterious effects of superoxide anion but also to preserve NO activity and prevent peroxynitrite formation. Peroxynitrous Acid 165-178 superoxide dismutase 3 Homo sapiens 5-11 7583586-5 1995 The EC-SOD concentration in the human arterial wall extracellular space is high enough to efficiently suppress the putative pathological effects of the superoxide radical, such as oxidation of LDL and reaction with nitric oxide to form the deleterious peroxynitrite. Peroxynitrous Acid 252-265 superoxide dismutase 3 Homo sapiens 4-10
