Biological hydropersulfides and related polysulfides – a new concept and perspective in redox biology [PDF]

open access: yes, 2018
The chemical biology of thiols (RSH, e.g., cysteine and cysteine‐containing proteins/peptides) has been a topic of extreme interest for many decades due to their reported roles in protein structure/folding, redox signaling, metal ligation, cellular ...

Identification of H2S3 and H2S produced by 3-mercaptopyruvate sulfurtransferase in the brain. [PDF]

open access: yesSci Rep, 2015
AbstractHydrogen polysulfides (H2Sn) have a higher number of sulfane sulfur atoms than hydrogen sulfide (H2S), which has various physiological roles. We recently found H2Sn in the brain. H2Sn induced some responses previously attributed to H2S but with much greater potency than H2S.

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.

Evidence of endogenously produced hydrogen sulfide (H2S) and persulfidation in male reproduction

open access: yesScientific Reports, 2022
Persulfidation contributes to a group of redox post-translational modifications (PTMs), which arise exclusively on the sulfhydryl group of cysteine as a result of hydrogen sulfide (H2S) action.

Inhibition of hydrogen sulfide biosynthesis sensitizes lung adenocarcinoma to chemotherapeutic drugs by inhibiting mitochondrial DNA repair and suppressing cellular bioenergetics [PDF]

open access: yes, 2016
Therapeutic manipulation of the gasotransmitter hydrogen sulfide (H(2)S) has recently been proposed as a novel targeted anticancer approach. Here we show that human lung adenocarcinoma tissue expresses high levels of hydrogen sulfide (H(2)S) producing ...

H2S biosynthesis and catabolism: new insights from molecular studies [PDF]

open access: yes, 2017
Hydrogen sulfide (H2S) has profound biological effects within living organisms and is now increasingly being considered alongside other gaseous signalling molecules, such as nitric oxide (NO) and carbon monoxide (CO).

3-Mercaptopyruvate sulfurtransferase: an enzyme at the crossroads of sulfane sulfur trafficking

open access: yesBiological Chemistry, 2020
Abstract 3-Mercaptopyruvate sulfurtransferase (MPST) catalyzes the desulfuration of 3-mercaptopyruvate to generate an enzyme-bound hydropersulfide. Subsequently, MPST transfers the persulfide’s outer sulfur atom to proteins or small molecule acceptors. MPST activity is known to be involved in hydrogen sulfide generation, tRNA thiolation,

Hydrogen Sulfide Levels and Nuclear Factor‐Erythroid 2‐Related Factor 2 (NRF2) Activity Are Attenuated in the Setting of Critical Limb Ischemia (CLI)

open access: yesJournal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2015
Background Cystathionine γ‐lyase, cystathionine β‐synthase, and 3‐mercaptopyruvate sulfurtransferase are endogenous enzymatic sources of hydrogen sulfide (H2S).
