Graphical Abstract

Modular design of functional RNAs can be used to tailor molecular properties. Guanosine-rich sequences were introduced as switching devices for functional nucleic acids. TMPyP4 (see picture) was identified as the strongest ribozyme inhibitor known to date. When quadruplex-forming, G-rich sequences were attached to the ribozyme, the TMPyP4-mediated response was inverted from inhibition to activation of the ribozyme reaction.
