3. Oxidative Stress in Kidney Transplantation
They work together with glutathione peroxidase and catalase, and their activity is highly responsive to oxidative stress. Superoxide (O 2 •− ) is produced as a by-product of oxygen metabolism. SOD catalyzes the dismutation (or partitioning) of this radical into ordinary molecular oxygen (O 2 ) and H 2 O 2 .
