Streptomyces cells may use known enzymes to remove extra sulfane sulfur, and an unknown regulator is involved in the regulation of these enzymes. AdpA is a multi-functional transcriptional regulator universally present in Streptomyces spp. Herein, we report that AdpA was essential for Streptomyces coelicolor survival when facing external RSS stress. AdpA deletion also resulted in intracellular RSS accumulation. Thioredoxins and thioredoxin reductases were responsible for anti-RSS stress via reducing RSS to gaseous hydrogen sulfide (H2S). AdpA directly activated the expression of these enzymes at the presence of excess RSS. Since AdpA and thioredoxin systems are widely present in Streptomyces, this finding unveiled a new mechanism of anti-RSS stress by these bacteria.<\/jats:p>","DOI":"10.3390\/antiox12020312","type":"journal-article","created":{"date-parts":[[2023,1,30]],"date-time":"2023-01-30T05:57:23Z","timestamp":1675058243000},"page":"312","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["The Pleiotropic Regulator AdpA Regulates the Removal of Excessive Sulfane Sulfur in Streptomyces coelicolor"],"prefix":"10.3390","volume":"12","author":[{"given":"Ting","family":"Lu","sequence":"first","affiliation":[{"name":"State Key Laboratory of Microbial Technology, Shandong University, 72 Binhai Road, Qingdao 266237, China"},{"name":"School of Health and Life Sciences, University of Health and Rehabilitation Sciences, Qingdao 266071, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0398-8344","authenticated-orcid":false,"given":"Qingda","family":"Wang","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Microbial Technology, Shandong University, 72 Binhai Road, Qingdao 266237, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Qun","family":"Cao","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Microbial Technology, Shandong University, 72 Binhai Road, Qingdao 266237, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"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, 72 Binhai Road, Qingdao 266237, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5770-9016","authenticated-orcid":false,"given":"Luying","family":"Xun","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Microbial Technology, Shandong University, 72 Binhai Road, Qingdao 266237, China"},{"name":"School of Molecular Biosciences, Washington State University, Pullman, WA 991647520, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0483-5318","authenticated-orcid":false,"given":"Huaiwei","family":"Liu","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Microbial Technology, Shandong University, 72 Binhai Road, Qingdao 266237, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2023,1,29]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1066","DOI":"10.1523\/JNEUROSCI.16-03-01066.1996","article-title":"The possible role of hydrogen sulfide as an endogenous neuromodulator","volume":"16","author":"Abe","year":"1996","journal-title":"J.
