Characterization of PspE, a Secreted Sulfurtransferase of Escherichia coli
… and mutant strains deficient in pspE and other sulfurtransferase paralogs in medium with cyanide or cadmium was compared. The results indicated that neither PspE nor other E. coli rhodanese paralogs play roles in cyanide or cadmium detoxification. The physiological role of PspE remains to be …

Biochemical and genetic characterization of mercaptopyruvate sulfurtransferase and paralogous putative sulfurtransferases of Escherichia coli
Sulfurtransferases, including mercaptopyruvate sulfurtransferase and rhodanese, are widely distributed in living organisms. Mercaptopyruvate sulfurtransferase and rhodanese catalyze the transfer of sulfur from mercaptopyruvate and thiosulfate, respectively, to sulfur acceptors such as thiols or …

Genetic and biochemical characterization of YrkF, a novel two-domain sulfurtransferase in Bacillus subtilis
… and [Fe-S] clusters are essential for life. Sulfurtransferases are present in eukaryotes, eubacteria, and archaea and are believed to play important roles in mobilizing sulfur necessary for biosynthesis of these compounds and for normal cellular functions. The rhodanese homology domain is a …

A study of chemolithoautotrophic bacterial rhodanese, and its potential contribution to cyanide wastage during cyanidation of biooxidized concentrates
… The enzyme rhodanese (thiosulfate: cyanide sulfurtransferase EC 2.8.1.1) is also able to catalyze the formation of thiocyanate using thiosulfate and cyanide as substrates. Therefore, the most relevant members of the microbial consortium responsible for biooxidation of gold-bearing ores or …

FUNCTIONAL STUDIES OF THE FE-S CLUSTER BIOGENESIS BY SUF SYSTEM
… indicated that, unlike E. coli SufS-SufE, the sulfurtransferase reaction by SufS-SufU is not protected from the action of reducing agents.

Biophysical and Functional Characterization of the Persulfide Sensor CstR from Staphylococcus aureus
… (Copper-sensing operon repressor (CsoR)-like sulfurtransferase repressor). In this work, sulfide stress, as exogenous H2S or RSS, is identified as a strong inducer of the cst operon. Failure to express this operon or deletions of enzymes within results in loss cellular viability under sulfide …

Activity of the beta-cyanoalanine synthase pathway is associated with the response to abiotic stress by Arabidopsis thaliana.
… between the β-cyanoalanine and an alternative sulfurtransferase pathway. A. thaliana Col-0 and three SALK-line mutants with a T-DNA insertion for the genesAtCysA1, AtCysC1 and AtNIT4 were grown and exposed to water stress. Physiological and biochemical measurements were taken. The results …

Characterization of AgaR and YihW, Members of the DeoR Family of Transcriptional Regulators, and GlpE, a Rhodanese Belonging to the GlpR Regulon, Also a Member of the DeoR Family
… 12-kDa rhodanese (thiosulfate:cyanide sulfurtransferase). The enzyme was purified to near homogeneity and characterized. As shown for other characterized rhodaneses, kinetic analysis revealed that catalysis occurs via an enzyme-sulfur intermediate utilizing a double-displacement …

Characterization of two novel proteins containing the rhodanese homology domain: YgaP and YbbB of Escherichia coli
… some members of this family of proteins show sulfurtransferase activity in vitro, their specific physiological functions remain largely undefined. Fusion of a rhodanese domain to different protein domains of known or unknown functions provides important clues to the diverse roles for these …

Charakterisierung der Funktion der Rhodanese YnjE für die Molybdänkofaktor Biosynthese in Escherichia coli
… der rhodaneseähnlichen Proteine, Thiosulfat-Sulfurtransferasen und Mercaptopyruvat-Sulfurtransferasen, dienen nicht als Substrate für eine Persulfurierung YnjEs. Durch eine Austauschmutante des Cysteinrestes der aktiven Schleife von YnjE konnte nicht bestätigt werden, dass dieser …
