Cell Reports, 2023 Summary: During hypoxia, increases in cerebral blood flow maintain brain oxygen delivery. Here, we describe a mechanism of brain oxygen sensing that mediates the dilation of intraparenchymal cerebral blood vessels in response to reductions in oxygen ...

The Mechanisms of Thiosulfate Toxicity against Saccharomyces cerevisiae
Antioxidants, 2021 Elemental sulfur and sulfite have been used to inhibit the growth of yeasts, but thiosulfate has not been reported to be toxic to yeasts. We observed that thiosulfate was more inhibitory than sulfite to Saccharomyces cerevisiae growing in a common yeast ...

Sulfites Chemistry in Wines: From Reference Quantification Methods to More Sustainable Innovative Approaches. [PDF]
Compr Rev Food Sci Food SafABSTRACT Sulfites are widely used as preservatives in winemaking due to their antioxidant, anti‐enzymatic, and antimicrobial properties. However, dietary sulfites have been linked to adverse reactions in sensitive individuals, especially those with asthma.

Redox 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 ...

Agronomy, 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 Alters the Mitochondrial Network in Molybdenum Cofactor Deficiency
Frontiers in Genetics, 2021 Molybdenum cofactor deficiency (MoCD) is an autosomal recessive disorder belonging to the large family of inborn errors in metabolism. Patients typically present with encephalopathy and seizures early after birth and develop severe neurodegeneration ...

Identification of YdhV as the first molybdoenzyme binding a Bis-Mo-MPT cofactor in escherichia coli [PDF]
, 2019 The oxidoreductase YdhV in Escherichia coli has been predicted to belong to the family of molybdenum/tungsten cofactor (Moco/Wco)-containing enzymes. In this study, we characterized the YdhV protein in detail, which shares amino acid sequence homology ...

Microbial degradation of dimethylsulphide and related C1-sulphur compounds: organisms and pathways controlling fluxes of sulphur in the biosphere [PDF]
, 2010 Dimethylsulphide (DMS) plays a major role in the global sulphur cycle. It has important implications for atmospheric chemistry, climate regulation, and sulphur transport from the marine to the atmospheric and terrestrial environments.

Continuous chemotrophic growth and respiration of Chromatiaceae species at low oxygen concentrations [PDF]
, 1992 Endogenous and maximum respiration rates of nine purple sulfur bacterial strains were determined. Endogenous rates were below 10 nmol O2 · (mg protein · min)-1 for sulfur-free cells and 15–35 nmol O2 · (mg protein · min)-1 for cells containg ...
