31. It is found that the peroxide and superoxide stress responses are distinct in bacteria. 32. Formulations of superoxide dismutase are also reported to be effective in Peyronie's disease. 33. This model predicts a different mechanism involving a pterin radical and superoxide as critical intermediates. 34. Cysteine residues from MTs can capture harmful oxidant radicals like the superoxide and hydroxyl radicals. 35. When stored in air, it forms a yellow potassium superoxide coating and may ignite. 36. "' Potassium superoxide "'is the inorganic compound with the formula. 37. Other enzymes capable of producing superoxide are xanthine oxidase, NADPH oxidases and cytochromes P450. 38. The superoxide anion is formed directly from the one-electron reduction of molecular oxygen. 39. Nickel also acts as a negative regulator, repressing the transcription of other superoxide dismutases. 40. _Bioflavonoids; superoxide dismutase glutathione.
