Copper- and Zinc-containing Superoxide Dismutase Can Act as a Superoxide Reductase and a Superoxide Oxidase [PDF]
Journal of Biological Chemistry, 2000 The copper- and zinc-containing superoxide dismutase can catalyze the oxidation of ferrocyanide by O(2) as well as the reduction of ferricyanide by O(2). Thus, it can act as a superoxide dismutase (SOD), a superoxide reductase (SOR), and a superoxide oxidase (SOO).

Role of Protons in Superoxide Reduction by a Superoxide Reductase Analogue [PDF]
Inorganic Chemistry, 2005 Superoxide reduction by thiolate-ligated [FeII(SMe2N4(tren))]+ (1) involves two proton-dependent steps and a single peroxide intermediate, [FeIII(SMe2N4(tren))(OOH)]+ (2). An external proton donor is required, ruling out mechanisms involving H+ or H-atom abstraction from the ligand N-H.

FEBS Open Bio, EarlyView.Abruptly changing from aerobic to anaerobic conditions (sudden anaerobization) induced growth inhibition and a significant increase in intracellular labile ferrous iron in the aerotolerant anaerobe Amphibacillus xylanus. We found that free flavins mediate efficient electron transfer from NADH to ferric iron under anaerobic conditions, suggesting that ...

Extracellular superoxide dismutase VdSOD5 is required for virulence in Verticillium dahliae
Journal of Integrative Agriculture, 2021 Plants produce reactive oxygen species (ROS) to defend pathogens. To counteract this attack, certain pathogens express superoxide dismutases (SODs) to scavenge host-derived ROS.
