Abstract:
Disclosed is the crystal structure of a GEMM riboswitch from bound to c-di-GMP. The crystal structures show that the RNA binds the ligand within a three helix junction that involves base pairing and extensive base stacking. The symmetric c-di-GMP is recognized asymmetrically with respect to the both the bases and the backbone. Also disclosed are methods of identifying and using compounds and compositions that modulate GEMM riboswitches.
