Interspecies differences in rhodanese (thiosulfate sulfurtransferase, EC 2.8.1.1) activity in liver, kidney and plasma

open access: closedComparative Biochemistry and Physiology Part B: Comparative Biochemistry, 1987
Rhodanese levels have been measured in liver, kidney and plasma from a number of species. Liver activity was low in marmosets, pigeons and beagle bitches. Levels were high in rats and somewhat lower in hamsters and guinea pigs while levels in two strains of rabbits were intermediate between guinea pigs and marmosets.

The specificity of active-site alkylation by iodoacetic acid in the enzyme thiosulfate sulfurtransferase

open access: closedBiochimica et Biophysica Acta (BBA) - Protein Structure and Molecular Enzymology, 1982
The active-site sulfhydryl group in the enzyme thiosulfate sulfurtransferase (rhodanese; thiosulfate:cyanide sulfurtransferase; EC 2.8.1.1) is alkylated rapidly by iodoacetic acid in the free enzyme form, E, with complete loss of sulfurtransferase activity.

Structural studies of bovine liver thiosulfate sulfurtransferase II. S-carboxymethylation of the enzyme and sequence analysis of the tryptic cysteinyl peptides

open access: closedBiochimica et Biophysica Acta (BBA) - Protein Structure, 1972
Abstract 1. 1. Alkylation7 of the two free sulfhydryl groups in the monomer of thiosulfatesulfurtransferase A by iodo[14C]acetate has been studied with both the native enzyme and the reduced and denatured protein. Carboxymethylation of thiosulfate sulfurtransferase at 0 °C in 0.1 M glycine, pH 9.0, is attended by rapid inactivation of the enzyme ...

P13 Cardiovascular phenotyping in mice with thiosulfate sulfurtransferase gene knock-out

open access: closedNitric Oxide, 2013
Background Hydrogen sulfide (H2S) is increasingly recognised as a key cardiovascular mediator with effects on the heart and vasculature in health and disease [1] , [2] . H2S is generated endogenously via cystathionine gamma-lyase (CSE) and cystathionine beta-synthase (CBS), whilst bioavailability can also be increased by H2S donors.

Deficiency of thiosulfate sulfurtransferase mediates the dysfunction of renal tubular mitochondrial fatty acid oxidation in diabetic kidney disease

open access: closedCell Death & Differentiation
One of the main characteristics of diabetic kidney disease (DKD) is abnormal renal tubular fatty acid metabolism, especially defective fatty acid oxidation (FAO), accelerating tubular injury and tubulointerstitial fibrosis. Thiosulfate sulfurtransferase (TST), a mitochondrial enzyme essential for sulfur transfer, is reduced in metabolic diseases like ...

On the molecular weight of thiosulfate sulfurtransferase

Biochimica et Biophysica Acta (BBA) - Protein Structure, 1975
Bovine liver thiosulfate sulfurtransferase (rhodanese) (EC 2.8.1.1) HAS BEEN REPORTED TO EXIST IN SOLUTION IN A RAPID, PH-dependent equilibrium between monomeric and dimeric forms of molecular weights 18 500 and 37 000 (Volini, M., DeToma, F. and Westley, J. (1967), J. Biol. Chem. 242, 5220).

Encapsulation of thiosulfate: Cyanide sulfurtransferase by mouse erythrocytes

Toxicology and Applied Pharmacology, 1986
Murine carrier erythrocytes, prepared by hypotonic dialysis, were employed in the encapsulation of several compounds including [14C]sucrose, [3H]inulin, and bovine thiosulfate:cyanide sulfurtransferase (rhodanese), a mitochondrial enzyme which converts cyanide to thiocyanate.

Low expression of thiosulfate sulfurtransferase (rhodanese) predicts mortality in hemodialysis patients

Clinical Biochemistry, 2010
To test the hypothesis that impaired expression of the thiosulfate sulfurtransferase rhodanese is associated with oxidative stress and may predict mortality in hemodialysis patients.Sixty-two hemodialysis patients were investigated to determine protein and mRNA expression of rhodanese in monocytes.
