1975 Nature 7 Aug. 510/1 Research on superoxide dismutase has suggested that this enzyme may also have controlled oxygen toxicity in ancient living tissue.
1983 D. J. Weatherall et al. Oxf. Textbk. Med. I. vi. 66/1 Once an electron is successfully attached to an oxygen molecule it becomes a highly corrosive superoxide ion... Superoxide dismutase and various peroxidases have evolved to protect most cells from the effects of the spontaneous superoxide ion formation that occurs.
