Ligand binding by the tandem glycine riboswitch depends on aptamer dimerization but not double ligand occupancy

The glycine riboswitch predominantly exists as a tandem structure, with two adjacent, homologous ligand-binding domains (aptamers), followed by a single expression platform. The recent identification of a leader helix, the inclusion of which eliminates cooperativity between the aptamers, has reopene...
