发现SNIPE系统通过定位在细胞膜上直接切割噬菌体DNA,揭示了细菌防御噬菌体的新机制

📝 英文原版摘要

<p>Nature, Published online: 25 February 2026; <a href="https://www.nature.com/articles/s41586-026-10207-1">doi:10.1038/s41586-026-10207-1</a></p>A widespread bacterial defence system called SNIPE is shown to localize to the cell membrane, where it identifies and cleaves the DNA of infecting phage as it is injected into the bacterial cell.
