Using a broad set of microbiological, physicochemical (UV absorption, LC-MS, X-ray analysis) and <i>in silico</i> experiments, we were able to prove that PLP inhibits adenylosuccinate synthetase (AdSS) from <i>H. pylori</i> by the competition with GTP (IC<sub>50</sub><sup>eq</sup> ∼30 nM). This behaviour was attributed to formation of a Schiff base with a lysine residue (a covalent bond with Lys322 in the GTP binding site of AdSS) and was potentiated by the presence of vitamin C. This antibacterial activity of PLP gives hope for its future use against <i>H. pylori</i>.</p>","PeriodicalId":15769,"journal":{"name":"Journal of Enzyme Inhibition and Medicinal Chemistry","volume":"39 1","pages":"2372734"},"PeriodicalIF":5.6,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11571797/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141988056","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
