Role of hydrogen sulfide in health and disease

MedComm, Volume 5, Issue 9, September 2024.
Abstract In the past, hydrogen sulfide (H2S) was recognized as a toxic and dangerous gas; in recent years, with increased research, we have discovered that H2S can act as an endogenous regulatory transmitter. In mammals, H2S‐catalyzing enzymes, such as cystathionine‐β‐synthase, cystathionine‐γ‐lyase, and 3‐mercaptopyruvate sulfurtransferase, are ...

Structural Enzymology of Sulfide Oxidation by Persulfide Dioxygenase and Rhodanese [PDF]

, 2017
Hydrogen sulfide (H2S) is the third eukaryotic gaseous signaling molecule and evokes a broad range of physiological effects. H2S levels are governed by the rates of its production and clearance.

MarR family proteins sense sulfane sulfur in bacteria

mLife, Volume 3, Issue 2, Page 231-239, June 2024.
Abstract Members of the multiple antibiotic resistance regulator (MarR) protein family are ubiquitous in bacteria and play critical roles in regulating cellular metabolism and antibiotic resistance. MarR family proteins function as repressors, and their interactions with modulators induce the expression of controlled genes. The previously characterized

Oxidation of Hydrogen Sulfide to Polysulfide and Thiosulfate by a Carbon Nanozyme: Therapeutic Implications with an Emphasis on Down Syndrome

Advanced Materials, Volume 36, Issue 10, March 7, 2024.
Oxidized carbon nanozymes catalytically oxidize hydrogen sulfide to polysulfides and thiosulfate in an oxygen‐dependent manner. In this report the reaction kinetics of polysulfide and thiosulfate formation both in a cell‐free setting and intracellularly and present the possible role of these nanozymes as a supportive therapy in Down Syndrome, a ...

Persulfide-responsive transcriptional regulation and metabolism in bacteria.

Journal of Biochemistry (Tokyo), 2019
Hydrogen sulfide (H2S) impacts on bacterial growth both positively and negatively; it is utilized as an electron donor for photosynthesis and respiration, and it inactivates terminal oxidases and iron-sulfur clusters. Therefore, bacteria have evolved H2S-

Spectroscopic and Electronic Structure Study of ETHE1: Elucidating the Factors Influencing Sulfur Oxidation and Oxygenation in Mononuclear Nonheme Iron Enzymes

, 2018
ETHE1 is a member of a growing subclass of nonheme Fe enzymes that catalyzes transformations of sulfur-containing substrates without a cofactor. ETHE1 dioxygenates glutathione persulfide (GSSH) to glutathione (GSH) and sulfite in a reaction which is ...

Priming avocado with sodium hydrosulfide prior to frost conditions induces the expression of genes involved in protection and stress responses

Physiologia Plantarum, Volume 176, Issue 2, March/April 2024.
Abstract Priming plants with chemical agents has been extensively investigated as a means for improving their tolerance to many biotic and abiotic stresses. Earlier, we showed that priming young avocado (Persea americana Mill cv. ‘Hass’) trees with sodium hydrosulfide (NaHS), a donor of hydrogen sulfide, improves the response of photosynthesis to ...
