Graphical Abstract

The construction of an artificial riboswitch is based on a ligand–RNA pair without any molecular biology-based selection processes. The ligand selectively and significantly stabilized an RNA duplex containing an r(XGG)/r(XGG) sequence (X=U, A, G). The integration of the ligand-binding sequences into the 5′-untranslated region of mRNA provided an artificial riboswitch that was responsive to Z-NCTS.
