叶酸及其衍生物是合成嘌呤、嘧啶和某些氨基酸所必需的。针对叶酸代谢途径的抗叶酸抗生素通常用于治疗由细胞内单核细胞增生性李斯特菌(Listeria monuctogen,Lm)引起的李斯特菌病。在最近的mBio工作中,冯等人。试图了解叶酸代谢在LM毒力中的作用(Y.Fung,S.Chang,D.A.Portnoy,2023,mBio https://doi.org/10.1128/mbio.01074-23).作者发现,N-甲酰蛋氨酸是细菌用来启动蛋白质合成的一种氨基酸,对LM细胞内生长和致病至关重要。令人惊讶的是,嘌呤和胸腺嘧啶核苷被发现对LM感染是必不可少的。综上所述,这些结果表明,虽然LM可以从宿主细胞质中获得许多必要的营养物质,包括嘌呤和大多数氨基酸,但它需要N-甲酰蛋氨酸的生物合成来适当地调节感染过程中的翻译起始。
Folic acid and its derivatives are required for the synthesis of purines, pyrimidines, and some amino acids. Antifolate antibiotics that target the folic acid metabolism pathway are commonly used for the treatment of listeriosis caused by the intracellular pathogen Listeria monocytogenes (Lm). In recent work in mBio, Feng et al. sought to understand the role of folic acid metabolism in Lm virulence (Y. Feng, S. Chang, D. A. Portnoy, 2023, mBio https://doi.org/10.1128/mbio.01074-23). The authors discovered that N-formylmethionine, an amino acid utilized by bacteria to initiate protein synthesis, is crucial for Lm intracellular growth and pathogenesis. Surprisingly, purines and thymidine were found to be dispensable for Lm infection. Together these results demonstrate that while Lm can obtain many essential nutrients from the host cytosol, including purines and most amino acids, it requires N-formylmethionine biosynthesis to properly regulate translation initiation during infection.
