Transcription factor YcjW controls the emergency H2S production in E. coli

open access: yesNature Communications, 2019
Hydrogen sulfide (H2S) production in Escherichia coli is controlled by the sulfurtransferase 3MST. Here, the authors describe an alternative mechanism for H2S biosynthesis via activation of the thiosulfate sulfurtransferase PspE, a process mediated by ...

CoQ deficiency causes disruption of mitochondrial sulfide oxidation, a new pathomechanism associated with this syndrome [PDF]

open access: yes, 2017
Coenzyme Q (CoQ) is a key component of the mitochondrial respiratory chain, but it also has several other functions in the cellular metabolism. One of them is to function as an electron carrier in the reaction catalyzed by sulfide:quinone oxidoreductase (

H2S, Polysulfides, and Enzymes: Physiological and Pathological Aspects

open access: yesBiomolecules, 2020
We have been studying the general aspects of the functions of H2S and polysulfides, and the enzymes involved in their biosynthesis, for more than 20 years.

Conformational studies on Arabidopsis sulfurtransferase AtStr1 with spectroscopic methods [PDF]

open access: yes, 2007
Sulfurtransferases/rhodaneses (Str) are enzymes widely distributed in archaea, prokaryota and eukaryota, and catalyze the transfer of sulfur from a donor molecule to a thiophilic acceptor substrate.

Sequential Accumulation of ‘Driver’ Pathway Mutations Induces the Upregulation of Hydrogen-Sulfide-Producing Enzymes in Human Colonic Epithelial Cell Organoids

open access: yesAntioxidants, 2022
Recently, a CRISPR-Cas9 genome-editing system was developed with introduced sequential ‘driver’ mutations in the WNT, MAPK, TGF-β, TP53 and PI3K pathways into organoids derived from normal human intestinal epithelial cells.

The Quantitative Significance of the Transsulfuration Enzymes for H2S Production in Murine Tissues [PDF]

open access: yes, 2011
The enzymes of the transsulfuration pathway, cystathionine --synthase (CBS) and cystathionine --lyase (CSE), are important for the endogenous production of hydrogen sulfide (H2S), a gaseous signaling molecule. The relative contributions of CBS and CSE to

Promoter hypomethylation and overexpression of TSTD1 mediate poor treatment response in breast cancer

open access: yesFrontiers in Oncology, 2022
Epigenetic alterations play a pivotal role in cancer treatment outcomes. Using the methylation array data and The Cancer Genome Atlas (TCGA) dataset, we observed the hypomethylation and upregulation of thiosulfate sulfurtransferase–like domain containing

Past, present and future of cyanide antagonism research: From the early remedies to the current therapies. [PDF]

open access: yes, 2015
This paper reviews milestones in antidotal therapies for cyanide (CN) spanning early remedies, current antidotal systems and research towards next generation therapies. CN has been a part of plant defense mechanisms for millions of years.

Allyl sulfur compounds and cellular detoxification system: effects and perspectives in cancer therapy [PDF]

open access: yes, 2011
Natural organosulfur compounds (OSCs) have been shown to have chemopreventive effects and to suppress the proliferation of tumor cells in vitro through the induction of apoptosis.

In Vivo Anti-inflammatory Activity of Lipoic Acid Derivatives in Mice  [PDF]

open access: yes, 2013
Background: In mammals lipoic acid (LA) and its reduced form dihydrolipoic acid (DHLA) function as cofactors for multienzymatic complexes catalyzing the decarboxylation of α-ketoacids.
