Reactions of isolated persulfides provide insights into the interplay between H2S and persulfide reactivity.

ABSTRACT: Hydrogen sulfide is ubiquitous in biological systems and exerts function over a wide range of important physiological processes. Complementing free H2S, the reductant-labile sulfur pool plays significant roles in the translocation and action of sulfide, however the chemistry of reductant-labile sulfide sources has not been studied systematically. Using a combination of NMR and UV-Vis spectroscopy, we investigated the spectroscopic properties and reactivity of three isolated organic persulfides and report a simple model for persulfide reactivity, including their roles as nucleophiles, electrophiles, and sulfide donors.

Biosynthesis and Reactivity of Cysteine Persulfides in Signaling.

Project description:Hydrogen sulfide (H2S) elicits pleiotropic physiological effects ranging from modulation of cardiovascular to CNS functions. A dominant method for transmission of sulfide-based signals is via posttranslational modification of reactive cysteine thiols to persulfides. However, the source of the persulfide donor and whether its relationship to H2S is as a product or precursor is controversial. The transsulfuration pathway enzymes can synthesize cysteine persulfide (Cys-SSH) from cystine and H2S from cysteine and/or homocysteine. Recently, Cys-SSH was proposed as the primary product of the transsulfuration pathway with H2S representing a decomposition product of Cys-SSH. Our detailed kinetic analyses demonstrate a robust capacity for Cys-SSH production by the human transsulfuration pathway enzymes, cystathionine beta-synthase and ?-cystathionase (CSE) and for homocysteine persulfide synthesis from homocystine by CSE only. However, in the reducing cytoplasmic milieu where the concentration of reduced thiols is significantly higher than of disulfides, substrate level regulation favors the synthesis of H2S over persulfides. Mathematical modeling at physiologically relevant hepatic substrate concentrations predicts that H2S rather than Cys-SSH is the primary product of the transsulfuration enzymes with CSE being the dominant producer. The half-life of the metastable Cys-SSH product is short and decomposition leads to a mixture of polysulfides (Cys-S-(S)n-S-Cys). These in vitro data, together with the intrinsic reactivity of Cys-SSH for cysteinyl versus sulfur transfer, are consistent with the absence of an observable increase in protein persulfidation in cells in response to exogenous cystine and evidence for the formation of polysulfides under these conditions.

A Persulfide Donor Responsive to Reactive Oxygen Species: Insights into Reactivity and Therapeutic Potential.

Project description:Persulfides (RSSH) have been hypothesized as critical components in sulfur-mediated redox cycles and as potential signaling compounds, similar to hydrogen sulfide (H2 S). Hindering the study of persulfides is a lack of persulfide-donor compounds with selective triggers that release discrete persulfide species. Reported here is the synthesis and characterization of a ROS-responsive (ROS=reactive oxygen species), self-immolative persulfide donor. The donor, termed BDP-NAC, showed selectivity towards H2 O2 over other potential oxidative or nucleophilic triggers, resulting in the sustained release of the persulfide of N-acetyl cysteine (NAC) over the course of 2?h, as measured by LCMS. Exposure of H9C2 cardiomyocytes to H2 O2 revealed that BDP-NAC mitigated the effects of a highly oxidative environment in a dose-dependent manner over relevant controls and to a greater degree than common H2 S donors sodium sulfide (Na2 S) and GYY4137. BDP-NAC also rescued cells more effectively than a non-persulfide-releasing control compound in concert with common H2 S donors and thiols.

Acidity and nucleophilic reactivity of glutathione persulfide.

Project description:Persulfides (RSSH/RSS-) participate in sulfur trafficking and metabolic processes, and are proposed to mediate the signaling effects of hydrogen sulfide (H2S). Despite their growing relevance, their chemical properties are poorly understood. Herein, we studied experimentally and computationally the formation, acidity, and nucleophilicity of glutathione persulfide (GSSH/GSS-), the derivative of the abundant cellular thiol glutathione (GSH). We characterized the kinetics and equilibrium of GSSH formation from glutathione disulfide and H2S. A pKa of 5.45 for GSSH was determined, which is 3.49 units below that of GSH. The reactions of GSSH with the physiologically relevant electrophiles peroxynitrite and hydrogen peroxide, and with the probe monobromobimane, were studied and compared with those of thiols. These reactions occurred through SN2 mechanisms. At neutral pH, GSSH reacted faster than GSH because of increased availability of the anion and, depending on the electrophile, increased reactivity. In addition, GSS- presented higher nucleophilicity with respect to a thiolate with similar basicity. This can be interpreted in terms of the so-called α effect, i.e. the increased reactivity of a nucleophile when the atom adjacent to the nucleophilic atom has high electron density. The magnitude of the α effect correlated with the Brønsted nucleophilic factor, βnuc, for the reactions with thiolates and with the ability of the leaving group. Our study constitutes the first determination of the pKa of a biological persulfide and the first examination of the α effect in sulfur nucleophiles, and sheds light on the chemical basis of the biological properties of persulfides.

Characterization of patient mutations in human persulfide dioxygenase (ETHE1) involved in H2S catabolism.

Project description:Hydrogen sulfide (H(2)S) is a recently described endogenously produced gaseous signaling molecule that influences various cellular processes in the central nervous system, cardiovascular system, and gastrointestinal tract. The biogenesis of H(2)S involves the cytoplasmic transsulfuration enzymes, cystathionine β-synthase and γ-cystathionase, whereas its catabolism occurs in the mitochondrion and couples to the energy-yielding electron transfer chain. Low steady-state levels of H(2)S appear to be controlled primarily by efficient oxygen-dependent catabolism via sulfide quinone oxidoreductase, persulfide dioxygenase (ETHE1), rhodanese, and sulfite oxidase. Mutations in the persulfide dioxgenase, i.e. ETHE1, result in ethylmalonic encephalopathy, an inborn error of metabolism. In this study, we report the biochemical characterization and kinetic properties of human persulfide dioxygenase and describe the biochemical penalties associated with two patient mutations, T152I and D196N. Steady-state kinetic analysis reveals that the T152I mutation results in a 3-fold lower activity, which is correlated with a 3-fold lower iron content compared with the wild-type enzyme. The D196N mutation results in a 2-fold higher K(m) for the substrate, glutathione persulfide.

Persulfide reactivity in the detection of protein s-sulfhydration.

Project description:Hydrogen sulfide (H2S) has emerged as a new member of the gaseous transmitter family of signaling molecules and appears to play a regulatory role in the cardiovascular and nervous systems. Recent studies suggest that protein cysteine S-sulfhydration may function as a mechanism for transforming the H2S signal into a biological response. However, selective detection of S-sulfhydryl modifications is challenging since the persulfide group (RSSH) exhibits reactivity akin to other sulfur species, especially thiols. A modification of the biotin switch technique, using S-methyl methanethiosulfonate (MMTS) as an alkylating reagent, was recently used to identify a large number of proteins that may undergo S-sulfhydration, but the underlying mechanism of chemical detection was not fully explored. To address this key issue, we have developed a protein persulfide model and analogue of MMTS, S-4-bromobenzyl methanethiosulfonate (BBMTS). Using these new reagents, we investigated the chemistry in the modified biotin switch method and examined the reactivity of protein persulfides toward different electrophile/nucleophile species. Together, our data affirm the nucleophilic properties of the persulfide sulfane sulfur and afford new insights into protein S-sulfhydryl chemistry, which may be exploited in future detection strategies.

Interplay between Surface Chemistry, Precursor Reactivity, and Temperature Determines Outcome of ZnS Shelling Reactions on CuInS<sub>2</sub> Nanocrystals.

Project description:ZnS shelling of I-III-VI2 nanocrystals (NCs) invariably leads to blue-shifts in both the absorption and photoluminescence spectra. These observations imply that the outcome of ZnS shelling reactions on I-III-VI2 colloidal NCs results from a complex interplay between several processes taking place in solution, at the surface of, and within the seed NC. However, a fundamental understanding of the factors determining the balance between these different processes is still lacking. In this work, we address this need by investigating the impact of precursor reactivity, reaction temperature, and surface chemistry (due to the washing procedure) on the outcome of ZnS shelling reactions on CuInS2 NCs using a seeded growth approach. We demonstrate that low reaction temperatures (150 °C) favor etching, cation exchange, and alloying regardless of the precursors used. Heteroepitaxial shell overgrowth becomes the dominant process only if reactive S- and Zn-precursors (S-ODE/OLAM and ZnI2) and high reaction temperatures (210 °C) are used, although a certain degree of heterointerfacial alloying still occurs. Remarkably, the presence of residual acetate at the surface of CIS seed NCs washed with ethanol is shown to facilitate heteroepitaxial shell overgrowth, yielding for the first time CIS/ZnS core/shell NCs displaying red-shifted absorption spectra, in agreement with the spectral shifts expected for a type-I band alignment. The insights provided by this work pave the way toward the design of improved synthesis strategies to CIS/ZnS core/shell and alloy NCs with tailored elemental distribution profiles, allowing precise tuning of the optoelectronic properties of the resulting materials.

Functional asymmetry and chemical reactivity of CsoR family persulfide sensors.

Project description:CstR is a persulfide-sensing member of the functionally diverse copper-sensitive operon repressor (CsoR) superfamily. While CstR regulates the bacterial response to hydrogen sulfide (H2S) and more oxidized reactive sulfur species (RSS) in Gram-positive pathogens, other dithiol-containing CsoR proteins respond to host derived Cu(I) toxicity, sometimes in the same bacterial cytoplasm, but without regulatory crosstalk in cells. It is not clear what prevents this crosstalk, nor the extent to which RSS sensors exhibit specificity over other oxidants. Here, we report a sequence similarity network (SSN) analysis of the entire CsoR superfamily, which together with the first crystallographic structure of a CstR and comprehensive mass spectrometry-based kinetic profiling experiments, reveal new insights into the molecular basis of RSS specificity in CstRs. We find that the more N-terminal cysteine is the attacking Cys in CstR and is far more nucleophilic than in a CsoR. Moreover, our CstR crystal structure is markedly asymmetric and chemical reactivity experiments reveal the functional impact of this asymmetry. Substitution of the Asn wedge between the resolving and the attacking thiol with Ala significantly decreases asymmetry in the crystal structure and markedly impacts the distribution of species, despite adopting the same global structure as the parent repressor. Companion NMR, SAXS and molecular dynamics simulations reveal that the structural and functional asymmetry can be traced to fast internal dynamics of the tetramer. Furthermore, this asymmetry is preserved in all CstRs and with all oxidants tested, giving rise to markedly distinct distributions of crosslinked products. Our exploration of the sequence, structural, and kinetic features that determine oxidant-specificity suggest that the product distribution upon RSS exposure is determined by internal flexibility.

Entropic factors provide unusual reactivity and selectivity in epoxide-opening reactions promoted by water.

Project description:Despite the myriad of selective enzymatic reactions that occur in water, chemists have rarely capitalized on the unique properties of this medium to govern selectivity in reactions. Here we report detailed mechanistic investigations of a water-promoted reaction that displays high selectivity for what is generally a disfavored product. A combination of structural and kinetic data indicates not only that synergy between substrate and water suppresses undesired pathways but also that water promotes the desired pathway by stabilizing charge in the transition state, facilitating proton transfer, doubly activating the substrate for reaction, and perhaps most remarkably, reorganizing the substrate into a reactive conformation that leads to the observed product. This approach serves as an outline for a general strategy of exploiting solvent-solute interactions to achieve unusual reactivity in chemical reactions. These findings may also have implications in the biosynthesis of the ladder polyether natural products, such as the brevetoxins and ciguatoxins.

Cyclic Acyl Disulfides and Acyl Selenylsulfides as the Precursors for Persulfides (RSSH), Selenylsulfides (RSeSH), and Hydrogen Sulfide (H2S).

Project description:The reactions of three model compounds (1-3) for cyclic acyl disulfides and cyclic acyl selenylsulfides are studied. These compounds were found to be effective precursors for persulfides (RSSH) and selenylsulfides (RSeSH) upon reacting with nucleophilic species. They could also act as H2S donors when interacting with cellular thiols. The most interesting discovery was the generation of RSeSH from compound 3 under mild conditions. Selenylsulfides (RSeSH) are expected to be important regulating molecules involved in Sec-related redox signaling. The method of producing RSeSH should allow researchers to better understand the chemical biology of RSeSH.

Quantitative Persulfide Site Identification (qPerS-SID) Reveals Protein Targets of H2S Releasing Donors in Mammalian Cells.

Project description:H2S is an important signalling molecule involved in diverse biological processes. It mediates the formation of cysteine persulfides (R-S-SH), which affect the activity of target proteins. Like thiols, persulfides show reactivity towards electrophiles and behave similarly to other cysteine modifications in a biotin switch assay. In this manuscript, we report on qPerS-SID a mass spectrometry-based method allowing the isolation of persulfide containing peptides in the mammalian proteome. With this method, we demonstrated that H2S donors differ in their efficacy to induce persulfides in HEK293 cells. Furthermore, data analysis revealed that persulfide formation affects all subcellular compartments and various cellular processes. Negatively charged amino acids appeared more frequently adjacent to cysteines forming persulfides. We confirmed our proteomic data using pyruvate kinase M2 as a model protein and showed that several cysteine residues are prone to persulfide formation finally leading to its inactivation. Taken together, the site-specific identification of persulfides on a proteome scale can help to identify target proteins involved in H2S signalling and enlightens the biology of H2S and its releasing agents.
