Based on\n                  <jats:italic>Escherichia coli<\/jats:italic>\n                  , most bacteria are thought to use a single accessory protein that monitors import to regulate phosphate homeostasis. This work reveals that most bacteria possess multiple distinct families of accessory regulators with each family regulating homeostasis in conjunction with a unique importer family. The antibiotic-resistant pathogen\n                  <jats:italic>Staphylococcus aureus<\/jats:italic>\n                  can obtain phosphate from divergent environments and possesses accessory-transporter pairs from all three identified groups. Investigations with\n                  <jats:italic>S. aureus<\/jats:italic>\n                  revealed that all three accessory proteins can regulate phosphate homeostasis, but that there is a hierarchy, which is dictated by the environment.

Thus, microbes possess not one, but multiple distinct groups of accessory regulatory proteins and this diversity enables them to control phosphate homeostasis across environments, including those encountered during infection.\n                <\/jats:p>","DOI":"10.1101\/2025.09.08.674922","type":"posted-content","created":{"date-parts":[[2025,9,9]],"date-time":"2025-09-09T04:15:22Z","timestamp":1757391322000},"source":"Crossref","is-referenced-by-count":0,"title":["Multiple clades of regulators contribute to bacterial phosphate homeostasis and pathogenesis"],"prefix":"10.64898","author":[{"given":"Caroline","family":"Vermilya","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Eliot S.","family":"Joya Sandoval","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jana N.","family":"Radin","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gary J.","family":"Olsen","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Bin Z.","family":"He","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8234-1113","authenticated-orcid":false,"given":"Thomas E.","family":"Kehl-Fie","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"54368","reference":[{"key":"2025091113350453000_2025.09.08.674922v1.1","doi-asserted-by":"crossref","unstructured":"Santos-Beneit F .
