Overexpression of Chloroplastic Cu/Zn Superoxide Dismutase in Plants
Molecular oxygen, although required for aerobic life, is toxic. The cellular damage caused by oxygen derivatives is known as oxidative stress. To survive, all aerobic organisms must posses the ability to protect themselves from oxidative stress. These protective mechanisms include both enzymatic and nonenzymatic systems. Superoxide dismutases (SODS) catalyze the vital first step in the enzymatic oxidative stress protective system.
