RADIATION PROTECTION BY SUPEROXIDE DISMUTASE

Photochemistry and Photobiology, 1978
Abstract— Protection of X‐irradiated mice by bovine superoxide dismutase is enhanced when the enzyme is given intravenously both before and after the exposure. With the combined treatment, the LD50(30) dose is increased from 734 ± 8 to 1144 ± 15rad for a dose reduction factor of 1.56 ± 0.04.

Lactoperoxidase, a dithionite ion dismutase

European Journal of Biochemistry, 1984
The dithionite ion is catalytically disproportionated by lactoperoxidase with Km= 0.36 mM in 100 mM glycine HCl pH 3.0. The products formed are thiosulfate and hydrogensulfite ions. The rate of reaction is considerably increased at low pH with a pKa at 3–3.5 possibly indicating the involvement of a carboxyl group.

Analysis of Superoxide Dismutase Activity

Current Protocols in Toxicology, 1999
AbstractMeasuring the activity of superoxide dismutases (SODs), the enzymes responsible for maintaining the steady state level of hydrogen peroxide, is challenging because the substrate is unstable at physiological pH and it reacts with itself. Fortunately the rate of reaction with dismutase is far greater than the rate of self reaction.
