Mycobacterium tuberculosis sulfurtransferase SseA is activated by its neighboring gene product Rv3284. [PDF]

open access: yesFEBS Lett
Tuberculosis remains a global health challenge and new therapeutic targets are required. Here, we characterized SseA, a sulfurtransferase from Mycobacterium tuberculosis involved in macrophage infection, and its interaction with the newly identified protein SufEMtb that activates SseA enzymatic activity.

Thiosulfate sulfurtransferase and UDP-glucuronosyltransferase activities in cholestatic rat liver induced by common bile duct ligation [PDF]

open access: goldExperimental & Molecular Medicine, 1997
We have investigated the effect of cholestasis on the hepatic thiosulfate sulfurtransferase (rhodanese) and UDP-glucuronosyltransferase (UDP-GT) activities in rats. Rhodanese activities in the liver cytosol, mitochondria and microsomal fractions as well as in the rat serum, and UDP-GT activity in the microsome have been investigated for a period of 42 ...

Studies of functionally important structural flexibility of thiosulfate sulfurtransferase

open access: bronzeBiophysical Journal, 1980
The enzyme thiosulfate sulfurtransferase (TST; rhodanese; EC 2.8.1.1) catalyzes the transfer of the outer sulfur of thiosulfate (S/sub 2/O/sub 3//sup - -/) to a variety of nucleophilic acceptors such as cyanide (CN/sup -/). During the course of this reaction the enzyme cycles through two stable isolatable catalytic intermediates: the free enzyme, (E ...

Sulfurtransferases and Cystathionine Beta-Synthase Expression in Different Human Leukemia Cell Lines

open access: yesBiomolecules, 2022
The studies concerned the expression of sulfurtransferases and cystathionine beta-synthase in six human leukemia cell lines: B cell acute lymphoblastic leukemia-B-ALL (REH cells), T cell acute lymphoblastic leukemia-T-ALL (DND-41 and MOLT-4 cells), acute

Structural and biochemical characterization of an encapsulin-associated rhodanese from Acinetobacter baumannii. [PDF]

open access: yesProtein Sci
Abstract Rhodanese‐like domains (RLDs) represent a widespread protein family canonically involved in sulfur transfer reactions between diverse donor and acceptor molecules. RLDs mediate these transsulfuration reactions via a transient persulfide intermediate, created by modifying a conserved cysteine residue in their active sites.

Hydrogen Sulfide Metabolizing Enzymes in the Intestinal Mucosa in Pediatric and Adult Inflammatory Bowel Disease

open access: yesAntioxidants, 2022
Hydrogen sulfide (H2S) is a toxic gas that has important regulatory functions. In the colon, H2S can be produced and detoxified endogenously. Both too little and too much H2S exposure are associated with inflammatory bowel disease (IBD), a chronic ...

Sulfane sulfur deficiency in malignant cells, increasing the inhibiting action of acetone cyanohydrin in tumor growth [PDF]

open access: yesActa Cirúrgica Brasileira, 2013
PURPOSE: To demonstrate the irreversible poisoning action of the acetone cyanohydrin (AC) in malignant cells. METHODS: Thirty male Swiss mice were inoculated with 1x10³ Ehrlich tumor (ET) cells. The mice were divided into three groups (n=10): CG (saline);

Hypertension and Aging Affect Liver Sulfur Metabolism in Rats

open access: yesCells, 2021
Hypertension and age are key risk factors for cardiovascular morbidity and mortality. Hydrogen sulfide (H2S), a gaseous transmitter, contributes significantly to regulating arterial blood pressure and aging processes.
