Microbes exist in a constant struggle with viruses and have evolved multiple defense mechanisms. Some of these, such as restriction endonucleases and CRISPR-Cas, have revolutionized genome editing methodology. A systematic strategy combining computation and experiment led to discovery of ten new defense systems that remain to be characterized mechanistically.
微生物与病毒之间存在着持续的斗争,并进化出了多种防御机制。其中一些机制,如限制内切酶和 CRISPR-Cas,已经彻底改变了基因组编辑方法。一项结合计算和实验的系统策略,导致发现了十种有待在机制上进行表征的新防御系统。
