Superoxide dismutase, a protein that protects against the effects of mitochondrial free radicals, can extend yeast lifespan in stationary phase when overexpressed.
32.
Superoxide dismutase ( SOD ) helps to slow the creation of ROS, ultimately playing a key role in the defense against cell damage.
33.
While serving as a graduate student, he and his supervisor Irwin Fridovich were the first to describe the enzymatic activity of superoxide dismutase.
34.
In particular, expression of iron superoxide dismutase ( Fe-SOD ) is repressed by nickel in " Streptomyces coelicolor ".
35.
These SCS's are synthetic versions of superoxide dismutase and catalase, which are naturally occurring enzymes involved in the control of oxidative stress.
36.
The skin contains several antioxidants, including vitamin E, coenzyme Q10, ascorbate, carotenoids, superoxide dismutase, catalase, and glutathione peroxidase.
37.
The operative factor is a gene found in some patients with familial ALS . This gene elicits the production of an abnormal form of superoxide dismutase.
38.
Several antioxidant enzymes such as superoxide dismutase, catalase, glutathione peroxidase, glutathione reductase, glutathione S-transferase etc . protect DNA from oxidative stress.
39.
In higher plants, superoxide dismutase enzymes ( SODs ) act as antioxidants and protect cellular components from being oxidized by reactive oxygen species ( ROS ).
40.
Some of the cellular and molecular effects underlying this observation are : the secretions contain antioxidant Superoxide dismutase and Glutathione S-transferase ( GSTs ) activities.
