Noun
dismutase (plural dismutases)
(biochemistry) Any of several enzymes that catalyze dismutation reactions.
Molecular At a molecular level, insulin resistance has been proposed to be a reaction to excess nutrition by superoxide dismutase in cell mitochondria that acts as an antioxidant defense mechanism. Source: Internet
Moreover, superoxide dismutase has the largest k cat /K M (an approximation of catalytic efficiency) of any known enzyme (~7 x 10 9 M −1 s −1 ), citation this reaction being limited only by the frequency of collision between itself and superoxide. Source: Internet
Several antioxidant enzymes such as superoxide dismutase, catalase, glutathione peroxidase, glutathione reductase, glutathione S-transferase etc. protect DNA from oxidative stress. Source: Internet
