Superoxide dismutase (EC 18.104.22.168) and catalase (EC 22.214.171.124) are important enzymes involved in protection of the cell from harmful effects of oxidative degradation. The respective substrates for these enzymes, superoxide anion and hydrogen peroxide, can be generated within the cell either by normal metabolism or by ionizing radiation. The hypothesis that the inherent radiosensitivity associated with the human autosomal recessive disease Ataxia telangiectasia is due to decreased levels of SOD and/or catalase was tested. The results suggest that fibroblast cells derived from ataxia patients are normal with respect to these two enzymes.
