SAM-VI Riboswitch Dynamics by Single-Molecule FRET
2026-09-29
Xue and colleagues used position-selective RNA labeling with single-molecule FRET to resolve how Mg2+ and SAM jointly control SAM-VI riboswitch conformational states. The study identifies ligand-ready intermediate ensembles and shows how SAM stabilizes regulatory structures that repress downstream SAM synthase translation, providing a dynamic complement to static structural models.
