Thiiranes: Intelligent Molecules for S-Persulfidation
Journal of the American Chemical SocietyThis study presents a global strategy for the transsulfuration of intracellular thiols (RSH) to persulfides (RSSH). Thiiranes comprising fluorenyl/diphenyl and malonate ester moieties directly convert intercellular RSH to low-molecular-weight RSSH in cells.

Biological chemistry of hydrogen sulfide and persulfides
Archives of Biochemistry and Biophysics, 2017Hydrogen sulfide (H2S) has been traditionally considered to be a toxic molecule for mammals. However, it can be formed endogenously and exert physiological effects with potential health benefits. H2S can partition two-fold in biological membranes and traverse them rapidly, diffusing between compartments.

A modified protein persulfidation detection method
Acta Physiologiae Plantarum, 2020As a gastransmitter, hydrogen sulfide (H2S) plays an important role in regulating plant growth and stress resistance. The proposed functional mechanism of H2S is persulfidation, a kind of posttranslational modification on free cysteine residues of proteins, which is also called S-sulfhydration previously. At present, biotin switch assay is an effective

Transfer of persulfide sulfur from thiocystine to rhodanese
Biochimica et Biophysica Acta (BBA) - Enzymology, 1979THiocystine (bis-[2-amino-2-carboxyethyl]trisulfide) is a natural substrate for rhodanese (thiosulfate:cyanide sulfurtransferase, EC 2.8.1.1). Analogs of thiocystine were prepared by eliminating the carboxyl or amino group or by lengthening the carbon chain.

Persulfide Signaling in Stress-Initiated Calmodulin Kinase Response
Antioxidants & Redox Signaling, 2020Significance: Calcium ion (Ca2+)/calmodulin (CaM)-dependent protein kinases (CaMKs) are activated by phosphorylation of a crucial threonine residue either by itself (CaMKII) or by upstream kinases, CaMK kinases (CaMKKs) (CaMKI and CaMKIV). CaMKs, present in most mammalian tissues, can phosphorylate many downstream targets, thereby regulating numerous ...

In support of the key features of sulfur transfer in the proposed mechanisms of 4-thiouridine generation, the enzyme ThiI can turn over only once in the absence of reductants of disulfide bonds, and Cys-456 of ThiI receives the sulfur transferred from the persulfide group of the sulfurtransferase IscS.

Measurement of Protein Persulfidation: Improved Tag-Switch Method
2019Hydrogen sulfide (H2S) is an endogenously produced signaling gasotransmitter, generated by the enzymes cystathionine γ-lyase, cystathionine β-synthase, and 3-mercaptopyruvate sulfurtransferase. The involvement of H2S in numerous physiological, as well as pathophysiological conditions, was established over the past decade. However, the exact mechanism(s)
