Abstract

Dihydrogen sulfide recently emerged as a biological signaling molecule with important physiological roles and significant pharmacological potential. Chemically plausible explanations for its mechanisms of action have remained elusive, however. Here, we report that H(2)S reacts with S-nitrosothiols to form thionitrous acid (HSNO), the smallest S-nitrosothiol. These results demonstrate that, at the cellular level, HSNO can be metabolized to afford NO(+), NO, and NO(-) species, all of which have distinct physiological consequences of their own. We further show that HSNO can freely diffuse through membranes, facilitating transnitrosation of proteins such as hemoglobin. The data presented in this study explain some of the physiological effects ascribed to H(2)S, but, more broadly, introduce a new signaling molecule, HSNO, and suggest that it may play a key role in cellular redox regulation.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • S-nitrosothiols rapidly react with sulfide in vitro, leading to formation of S/N-hybrid species including thionitrite and nitrosopersulfide.

    “the latter have been shown to rapidly react with sulfide in vitro, leading to formation of S/N-hybrid species including thionitrite (SNO -) and nitrosopersulfide (SSNO -).”

    From On the chemical biology of the nitrite/sulfide interaction (2015) · cites this paper as [18]

  • Further products of the reaction might be nitroxyl and nitrous oxide (N2O).

    “As expected, by considering the chemistry of the reaction (Fig. 2), further products of this reaction might be nitroxyl as proposed previously [16,18,30], and nitrous oxide (N2O).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
