841-极端环境微生物目录:全球多样性与抗菌药物发现资源

from 聊聊Sci

该研究通过整合全球两千多个宏基因组和三千余个分离株基因组,构建了极端环境微生物目录(EEMC),显著扩展了人类对生命极限边界的认知。EEMC 涵盖了超过七万个细菌和古菌基因组,其中包含大量新物种和数以亿计的未知基因,揭示了极端生境中巨大的生物合成潜力。科研人员利用蛋白质大语言模型(pLLMs)从该资源中精准挖掘出数千种候选抗菌肽(cAMPs),并通过实验证实了其高效的杀菌能力与低细胞毒性。这项工作不仅为理解微生物的生态适应机制提供了关键数据支撑,还展示了人工智能驱动下从极端自然界中发现新型药物的巨大前景。因此,该目录已成为探索全球微生物多样性及推动生物技术创新的重要基石。References: Jiang P, Liang Z, Kovacevic V, et al.
