in times of oxidative stress, enzyme efficiently diverts intracellular reducing equivalents to superoxide |
| 1.15.1.2 | more |
in contrast to superoxide dismutases, EC 1.15.1.1, SORs do not catalyze the dismutation reaction of superoxide, but catalyze a one-electron reduction of superoxide to produce H2O2, without formation of O2, electron transfer mechanisms, detailed overview |
| 1.15.1.2 | reduced desulforedoxin + superoxide + 2 H+ |

| 1.15.1.2 | reduced rubredoxin + superoxide + 2 H+ |
superoxide reductase mediates reduction of superoxide to hydrogen peroxide in an NADPH-dependent manner via a coupled reaction between NAD(P)H:rubredoxin oxidoreductase, rubredoxin, and superoxide reductase |
| 1.15.1.2 | reduced rubredoxin + superoxide + 2 H+ |
the enzyme may contribute to the protection of cells from oxygen radicals formed by flavoproteins during periodic exposure to oxygen in natural environments |
| 1.15.1.2 | reduced rubredoxin + superoxide + H+ |

| 1.15.1.2 | reduced rubredoxin + superoxide + H+ |
desulfoferrodoxin is the key factor in the superoxide reductase dependent part of an alternative pathway for detoxification of reactive oxygen species in this obligate anaerobic bacterium |
| 1.15.1.2 | reduced rubredoxin + superoxide + H+ |
superoxide scavenging by superoxide reductases constitutes an alternative detoxifying system to the canonical superoxide dismutases, instead of dismutating superoxide, SORs catalyse only the reductive reaction, forming hydrogen peroxide as a product |
| 1.15.1.2 | reduced rubredoxin + superoxide + H+ |
the enzyme catalyzes the one-electron reduction of O2 to H2O2, providing an antioxidant defense in some bacteria |
