Is Thiosulfate Sulfurtransferase the Colonic Sulfide Oxidase?
Digestive Diseases and Sciences, 2007Neither sodium sulfide nor sodium thiosulfate is soluble in ethanol but NaHS.H20 is. We then removed insoluble material from our preparations by centrifugation and discarded it. The ethanol-soluble material was used in the experiments. In this later study we were able to show that removal of thiosulfate sulfurtransferase (TST), using a specific ...

Redox Regulation of Mammalian 3-Mercaptopyruvate Sulfurtransferase
2015A cystine-catabolizing enzyme, 3-mercaptopyruvate sulfurtransferase catalyzes the trans-sulfuration reaction of mercaptopyruvate or thiosulfate to thiol-containing compounds or cyanide. During the catalytic process, persulfide is formed at the catalytic site cysteine residue and a sulfur-acceptor substrate donates the outer sulfur of the persulfide to ...

Rhodanese domain-containing sulfurtransferases
2019Sulfur is an essential element for the growth and development of plants, which synthesize cysteine and methionine from the reductive assimilation of sulfate. Besides its incorporation into proteins, cysteine is the building block for the biosynthesis of numerous sulfur-containing molecules and cofactors.

[38] 3-Mercaptopyruvate sulfurtransferase
1981Publisher Summary 3-Mercaptopyruvate sulfurtransferase catalyzes the cleavage of a carbon–sulfur bond and the transfer of the sulfur atom from 3-mercaptopyruvate to any of a variety of thiophiles, including thiols, cyanide, sulfite, and sulfinates. This chapter deals with the purification of the 3-mercaptopyruvate sulfurtransferase from the bovine ...

Thiosulfate sulfurtransferase (rhodanese) in forest soils
Folia Microbiologica, 1987Concentrations of thiosulfate sulfurtransferase (rhodanese; EC 2.8.1.1) in soils of five types of forest stands (spruce and pine stands without ground vegetation, and mountain ash, birch and pine stands with grass cover) were followed. Soils from grassed stands contained much higher concentrations of the enzyme than soils without ground vegetation.
