Interrupted adenylation domains are enigmatic fusions, in which one enzyme is inserted into another to form a highly unusual bifunctional enzyme. We present the first crystal structure of an interrupted adenylation domain that reveals a unique embedded methyltransferase. The structure and functional data provide insight into how these enzymes N-methylate amino acid precursors en route to nonribosomal peptides.

中断的腺苷酸化结构域的骨架N-甲基化的结构基础

中断的腺苷酸化结构域是神秘的融合体,其中一种酶插入另一种酶以形成高度不常见的双功能酶。我们提出了一个中断的腺苷酸化域的第一个晶体结构,揭示了一个独特的嵌入式甲基转移酶。结构和功能数据提供了有关这些酶N-甲基化氨基酸前体如何转化为非核糖体肽的见解。
