Sulfite Oxidase Activity Level Determines the Sulfite Toxicity Effect in Leaves and Fruits of Tomato Plants

open access: yesAgronomy, 2020
Increasing plant tolerance to sulfites/SO2 can lead to the development of tolerant crops to biotic and abiotic stresses. Plant sulfite oxidase (SO) is a molybdo-enzyme that oxidizes excess SO2/sulfite into non-toxic sulfate.

Sulfite-induced protein radical formation in LPS aerosol-challenged mice: Implications for sulfite sensitivity in human lung disease

open access: yesRedox Biology, 2018
Exposure to (bi)sulfite (HSO3–) and sulfite (SO32–) has been shown to induce a wide range of adverse reactions in sensitive individuals. Studies have shown that peroxidase-catalyzed oxidation of (bi)sulfite leads to formation of several reactive free ...

The History of Animal and Plant Sulfite Oxidase—A Personal View

open access: yesMolecules, 2023
Sulfite oxidase is one of five molybdenum-containing enzymes known in eukaryotes where it catalyzes the oxidation of sulfite to sulfate. This review covers the history of sulfite oxidase research starting out with the early years of its discovery as a ...

Sulfite oxidase activity of cytochrome c: Role of hydrogen peroxide

open access: yesBiochemistry 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.

Recombinant Thaumatin-Like Protein (rTLP) and Chitinase (rCHI) from Vitis vinifera as Models for Wine Haze Formation

open access: yesMolecules, 2022
Cross-linking net aggregates of thermolabile thaumatin-like proteins (TLPs) and chitinases (CHIs) are the primary source of haze in white wines. Although bentonite fining is still routinely used in winemaking, alternative methods to selectively remove ...

Sulfite oxidation in Chlorobaculum tepidum

open access: yesFrontiers in Microbiology, 2011
The green sulfur bacterium Chlorobaculum tepidum is proposed to oxidize sulfide and elemental sulfur via sulfite as an obligate intermediate. The sulfite pool is predicted to be contained in the cytoplasm and be oxidized by the concerted action of AprBA,

DNA damage in a solution containing copper(II) ions and ascorbic acid: Effect of the presence of sulfite

open access: yesBrazilian 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.

Synthesis and Evaluation of Cyclic Sulfite Diesters as Sulfur Dioxide (SO2) Donors [PDF]

open access: yes, 2019
Although sulfur dioxide (SO2) finds widespread use in the food industry as its hydrated form, sulfite, a number of aspects of SO2 biology remain to be completely understood. Among the tools available for intracellular enhancement of SO2, most suffer from
