Several key enzymes act as catalysts in redox signaling:
Superoxide Dismutase (SOD): Catalyzes the dismutation of superoxide radicals into oxygen and hydrogen peroxide. Catalase: Decomposes hydrogen peroxide into water and oxygen. Glutathione Peroxidase (GPx): Reduces hydrogen peroxide and organic hydroperoxides using glutathione. Peroxiredoxins (Prx): Reduce peroxides and play a role in cell signaling and antioxidant defense.
