Abstact

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.
