Description générale

Research area: Cell Signaling

Superoxide dismutase (SOD) is a redox-active metalloenzyme expressed in both aerobic and anaerobic living organisms. Bovine superoxide dismutase or CuZn SOD is a homodimer with each subunit containing one zinc and one copper ion.

Application

Superoxide dismutase from bovine erythrocytes has been used:

  • in a study to assess a kinetic model of radiation-induced inactivation of superoxide dismutase in nitrous oxide-saturated solutions
  • in a study to investigate the possible participation of superoxide anion in the intestinal tryptophan 2,3-dioxygenase reaction
  • to investigate its effect on the hemolysis rate of human RBCs and hemoglobin-nitric oxide complex (HbNO) stability in human erythrocytes
  • in combination with catalase to study its effect on cell differentiation in vitro
  • to quantify superoxide levels and study their effect on reactivity in mouse pulmonary arteries through chemiluminescence and cytochrome C reduction methods

Actions biochimiques/physiologiques

Superoxide Dismutase from bovine erythrocytes catalyzes the dismutation of superoxide radicals to hydrogen peroxide and molecular oxygen. It serves as an antioxidant and plays a critical role in the defense of cells against the toxic effects of oxygen radicals. Competes with nitric oxide (NO) for superoxide anion (which reacts with NO to form peroxynitrite), thereby SOD promotes the activity of NO. SOD has also been shown to suppress apoptosis in cultured rat ovarian follicles, neural cell lines, and transgenic mice.

Définition de l'unité

One unit will inhibit reduction of cytochrome c by 50% in a coupled system with xanthine oxidase at pH 7.8 at 25 °C in a 3.0 ml reaction volume. Xanthine oxidase concentration should produce an initial ΔA550 of 0.025 ± 0.005 per min.

Aflatoxin contamination of crops is a worldwide problem, and elucidation of the regulatory mechanism of aflatoxin production, for example relative to the oxidative⁻antioxidative system, is needed. Studies have shown that oxidative stress induced by reactive oxygen species promotes aflatoxin production.

Articles

Oxidative stress is mediated, in part, by reactive oxygen species produced by multiple cellular processes and controlled by cellular antioxidant mechanisms such as enzymatic scavengers or antioxidant modulators. Free radicals, such as reactive oxygen species, cause cellular damage via cellular.
