Most type II restriction modification systems employ rigorous mechanisms to interrogate methylation in both DNA strands to distinguish between host and invader DNA. Type IIL enzymes like DrdV are an exception to this rule. In this issue of Structure, Shen et al. (2021) address how such enzymes make the distinction successfully.

限制修饰中自我与非自我的区别:IIL型酶的神秘案例

大多数 II 型限制性修饰系统采用严格的机制来询问两条 DNA 链中的甲基化,以区分宿主 DNA 和入侵者 DNA。像 DrdV 这样的 IIL 型酶是这个规则的一个例外。在本期结构中,Shen 等人。(2021) 解决了这些酶如何成功区分的问题。
