Investigating the Catalytic and the Metabolic Role of the Thiol Dioxygenase and a Sulfurtransferase in the mdo Operon from Pseudomonas aeruginosa [PDF]

open access: yes, 2019
Mammalian cysteine dioxygenase (CDO) is a mononuclear iron containing enzyme that belongs to the cupin superfamily. CDO catalyzes the oxidation of cysteine to cysteine sulfinic acid.

Role of hydrogen sulfide in health and disease

open access: yesMedComm, 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 ...

MarR family proteins sense sulfane sulfur in bacteria

open access: yesmLife, 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

open access: yesAdvanced 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 ...

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

open access: yesPhysiologia 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 ...

Mechanistic investigations of C-S bond formation in anaerobic ergothioneine biosynthesis and aerobic ovothiol biosynthesis [PDF]

open access: yes, 2022
Ergothioneine and ovothiol A are naturally occurring thiol-histidine derivatives. Both of them are suggested to be beneficial to human health. Ergothioneine has anti-inflammation and anti-oxidative properties and ovothiol has anti-proliferative ...
