However, how bacteria alleviate the pressure of sulfane sulfur accumulation remains largely unclear. In this study, we focused on the bacterium Cupriavidus pinatubonensis JMP134, which contains a complete Sox system. When soxCD was deleted, this bacterium temporarily produced sulfane sulfur when oxidizing thiosulfate. Persulfide dioxygenase (PDO) in concert with glutathione oxidizes sulfane sulfur to sulfite. Sulfite can spontaneously react with extra persulfide glutathione (GSSH) to produce thiosulfate, which can feed into the incomplete Sox system again and be oxidized to sulfate. Furthermore, the deletion strain lacking PDO and SoxCD produced volatile H2S gas when oxidizing thiosulfate. By comparing the oxidized glutathione (GSSG) between the wild-type and deletion strains, we speculated that H2S is generated during the interaction between sulfane sulfur and the glutathione\/oxidized glutathione (GSH\/GSSG) redox couple, which may reduce the oxidative stress caused by the accumulation of sulfane sulfur in bacteria. Thus, PDO and H2S release play a critical role in alleviating sulfane sulfur toxicity after the loss of soxCD in C. pinatubonensis JMP134.<\/jats:p>","DOI":"10.3390\/metabo13020218","type":"journal-article","created":{"date-parts":[[2023,2,2]],"date-time":"2023-02-02T05:44:45Z","timestamp":1675316685000},"page":"218","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Cupriavidus pinatubonensis JMP134 Alleviates Sulfane Sulfur Toxicity after the Loss of Sulfane Dehydrogenase through Oxidation by Persulfide Dioxygenase and Hydrogen Sulfide Release"],"prefix":"10.3390","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1517-0673","authenticated-orcid":false,"given":"Yufeng","family":"Xin","sequence":"first","affiliation":[{"name":"College of Life Sciences, Qufu Normal University, Qufu 273165, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yaxin","family":"Wang","sequence":"additional","affiliation":[{"name":"College of Life Sciences, Qufu Normal University, Qufu 273165, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Honglin","family":"Zhang","sequence":"additional","affiliation":[{"name":"College of Life Sciences, Qufu Normal University, Qufu 273165, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yu","family":"Wu","sequence":"additional","affiliation":[{"name":"College of Life Sciences, Qufu Normal University, Qufu 273165, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9950-1910","authenticated-orcid":false,"given":"Yongzhen","family":"Xia","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Microbial Technology, Shandong University, Qingdao 266237, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4997-0927","authenticated-orcid":false,"given":"Huanjie","family":"Li","sequence":"additional","affiliation":[{"name":"School of Medicine, Cheeloo College of Medicine, Shandong University, Jinan 250012, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiaohua","family":"Qu","sequence":"additional","affiliation":[{"name":"College of Life Sciences, Qufu Normal University, Qufu 273165, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,2,2]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"e01610-17","DOI":"10.1128\/AEM.01610-17","article-title":"Cupriavidus necator H16 uses flavocytochrome c sulfide dehydrogenase to oxidize self-produced and added sulfide","volume":"83","author":"Xia","year":"2017","journal-title":"Appl.
