| Sumario: | Clostridioides difficile adenine methyltransferase A (CamA) is required for the sporulation and colonization of the pathogen that causes gastrointestinal infections. Here, the authors characterise CamA kinetically and present its crystal structure bound to the DNA recognition sequence, which reveals DNA distortions including bending and the flipping of the target adenine out of the DNA helix, as well as protein conformational changes upon cofactor binding. |
