The unwanted by-products are superoxides and similar radicals, and also hydrogen peroxide ( which is produced from the radicals by superoxide dismutase enzymes ).
42.
But the researchers found that if they soaked the vessels first with the potent antioxidant enzyme superoxide dismutase, or SOD, the blood vessels did not constrict.
43.
The fortified forage, it turns out, is full of anti-oxidants like copper, vitamins C and E, superoxide dismutase, and glutathione reductase.
44.
During infection, some bacteria ( e . g ., " Burkholderia pseudomallei " ) therefore produce superoxide dismutase to protect themselves from being killed.
45.
It is presumed that superoxide kills bacteria directly, as the virulence of many pathogens is dramatically attenuated when their superoxide dismutase ( SOD ) genes are deleted.
46.
As well as the TIM ribbon drawing at the right, other hand-drawn examples are for prealbumin, flavodoxin, and Cu, Zn superoxide dismutase.
47.
SAFR-032 spores indicated that proteins conferring resistant traits ( superoxide dismutase ) were present in higher concentration in space-exposed spores when compared to controls.
48.
The antioxidant superoxide dismutase catalyses the formation of hydrogen peroxide from the superoxide anion through the following reaction : 2 O 2 " + 2H + ?
49.
Enzymes with this property are called " triose-phosphate isomerase, carbonic anhydrase, acetylcholinesterase, catalase, fumarase, ?-lactamase, and superoxide dismutase.
50.
The first type is the oxygen-dependent production of a superoxide, The superoxide is converted to hydrogen peroxide and singlet oxygen by an enzyme called superoxide dismutase.
