Two major positive contributors to NPQ are the carotenoid zeaxanthin, generated from violaxanthin by the enzyme violaxanthin de\u2010epoxidase (VDE or NPQ1), and the thylakoid protein PsbS (NPQ4). The involvement of the lumenal Deg proteases in the repair of PSII from photoinhibition prompted us to further explore their possible role in other responses of\n                    <jats:italic>Arabidopsis thaliana<\/jats:italic>\n                    to high light. Here we show that upon exposure to high light, the single\n                    <jats:italic>deg1<\/jats:italic>\n                    and the triple\n                    <jats:italic>deg158<\/jats:italic>\n                    mutants display different levels and kinetics of NPQ, compared with the\n                    <jats:italic>deg58<\/jats:italic>\n                    mutant and WT that behave alike. In response to high light, the two genotypes lacking Deg1 overaccumulate NPQ1 and NPQ4. After temporal inhibition of protein translation in vivo, the level of these two proteins in\n                    <jats:italic>deg1<\/jats:italic>\n                    is higher than in WT. Together, the results suggest that Deg1 represents a new level of regulation of the NPQ process through adjusting the quantity of NPQ1 and NPQ4 proteins, probably through their proteolysis.\n                  <\/jats:p>","DOI":"10.1111\/tpj.17263","type":"journal-article","created":{"date-parts":[[2025,2,26]],"date-time":"2025-02-26T00:57:29Z","timestamp":1740531449000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["The thylakoid lumen Deg1 protease affects non\u2010photochemical quenching via the levels of violaxanthin de\u2010epoxidase and\n                    <scp>PsbS<\/scp>"],"prefix":"10.1111","volume":"121","author":[{"given":"Elinor","family":"Aviv\u2010Sharon","sequence":"first","affiliation":[{"name":"Faculty of Agriculture The Robert H.
