Organelle-Targeted Fluorescent Probes for Sulfane Sulfur Species. [PDF]
Antioxidants (Basel), 2023 Sulfane sulfurs, which include hydropersulfides (RSSH), hydrogen polysulfides (H2Sn, n > 1), and polysulfides (RSnR, n > 2), play important roles in cellular redox biology and are closely linked to hydrogen sulfide (H2S) signaling. While most studies on sulfane sulfur detection have focused on sulfane sulfurs in the whole cell, increasing the ...

A Red Fluorescent Protein-Based Probe for Detection of Intracellular Reactive Sulfane Sulfur. [PDF]
Antioxidants (Basel), 2020 Reactive sulfane sulfur, including persulfide and polysulfide, is a type of regular cellular component, playing an antioxidant role. Its function may be organelle-dependent; however, the shortage of probes for detecting organellar reactive sulfane sulfur has hindered further investigation.

Detection of sulfane sulfur species in biological systems. [PDF]
Redox Biol, 2022 Sulfane sulfur species such as hydropersulfides (RSSH), polysulfides (RSnR), and hydrogen polysulfides (H2Sn) are critically involved in sulfur-mediated redox signaling, but their detailed mechanisms of action need further clarification. Therefore, there is a need to develop selective and sensitive sulfane sulfur detection methods to gauge a better ...

Isotope dilution mass spectrometry for the quantification of sulfane sulfurs [PDF]
Free Radical Biology and Medicine, 2014 Sulfane sulfurs are one type of important reactive sulfur species. These molecules have unique reactivity that allows them to attach reversibly to other sulfur atoms and exhibit regulatory effects in diverse biological systems. Recent studies have suggested that sulfane sulfurs are involved in signal transduction processes regulated by hydrogen sulfide

The Rhodanese PspE Converts Thiosulfate to Cellular Sulfane Sulfur in Escherichia coli. [PDF]
Antioxidants (Basel), 2023 Hydrogen sulfide (H2S) and its oxidation product zero-valent sulfur (S0) play important roles in animals, plants, and bacteria. Inside cells, S0 exists in various forms, including polysulfide and persulfide, which are collectively referred to as sulfane sulfur.

A sulfide-sensor and a sulfane sulfur-sensor collectively regulate sulfur-oxidation for feather degradation by Bacillus licheniformis. [PDF]
Commun Biol, 2023 AbstractBacillus licheniformis MW3 degrades bird feathers. Feather keratin is rich in cysteine, which is metabolized to produce hazardous sulfide and sulfane sulfur. A challenge to B. licheniformis MW3 growing on feathers is to detoxify them. Here we identified a gene cluster in B. licheniformis MW3 to deal with these toxicity.

Modified cyclodextrins solubilize elemental sulfur in water and enable biological sulfane sulfur delivery. [PDF]
Chem Sci, 2020 An important form of biological sulfur is sulfane sulfur, or S0, which is found in polysulfide and persulfide compounds as well as in elemental sulfur. Sulfane sulfur, often in the form of S8, functions as a key energy source in the metabolic processes of thermophilic Archaean organisms found in sulfur-rich environments and can be metabolized both ...

Metabolic Reprogramming of Sulfur in Hepatocellular Carcinoma and Sulfane Sulfur-Triggered Anti-Cancer Strategy. [PDF]
Front Pharmacol, 2020 Metabolic reprogramming is a cancer hallmark. Although the reprogramming of central carbon has been well documented, the role of sulfur metabolism has been largely overlooked. Additionally, the effects of sulfur are sometimes contradictory in tumorigenesis.
