Sulfite oxidase activity of cytochrome c: Role of hydrogen peroxide
Biochemistry and Biophysics Reports, 2016 In humans, sulfite is generated endogenously by the metabolism of sulfur containing amino acids such as methionine and cysteine. Sulfite is also formed from exposure to sulfur dioxide, one of the major environmental pollutants.

Level of Sulfite Oxidase Activity Affects Sulfur and Carbon Metabolism in Arabidopsis
Frontiers in Plant Science, 2021 Molybdenum cofactor containing sulfite oxidase (SO) enzyme is an important player in protecting plants against exogenous toxic sulfite. It was also demonstrated that SO activity is essential to cope with rising dark-induced endogenous sulfite levels and ...

Brazilian Journal of Pharmaceutical Sciences, 2021 Some antioxidant compounds have a pro-oxidant effect in the presence of transition metal ions, due to the reduction of Mn+ to M(n-1)+ with simultaneous formation of free radicals, which then promote DNA damage.

Sulfite Reductase Protects Plants against Sulfite Toxicity [PDF]
Plant Physiology, 2012 Abstract Plant sulfite reductase (SiR; Enzyme Commission 1.8.7.1) catalyzes the reduction of sulfite to sulfide in the reductive sulfate assimilation pathway. Comparison of SiR expression in tomato (Solanum lycopersicum ‘Rheinlands Ruhm’) and Arabidopsis (Arabidopsis thaliana) plants revealed that SiR is expressed in a different tissue ...

Sulfite Reduction in Mycobacteria [PDF]
Journal of Bacteriology, 2007 ABSTRACT Mycobacterium tuberculosis places an enormous burden on the welfare of humanity. Its ability to grow and its pathogenicity are linked to sulfur metabolism, which is considered a fertile area for the development of antibiotics, particularly because many of the sulfur acquisition steps in the bacterium are not ...
