The paper validates SreA as a functional SAM-I riboswitch in Listeria monocytogenes through ligand binding, structure, and transcription assays, showing it binds SAM at lower concentrations than other SAM riboswitches but does not terminate transcription.

This paper uses SAXS and SANS to analyze conformational changes in RNA:RNA complexes, validating and improving AlphaFold 3 predictions through isotope labeling and contrast matching.
