Abstrakt: A bimolecular ribozyme consisting of a core ribozyme (ΔP5 RNA) and an activator module (P5abc RNA) has been used as a platform to design assembled RNA nanostructures. The tight and specific assembly between the P5abc and ΔP5 modules depends on two sets of intermodule interactions. The interface between P5abc and ΔP5 must be controlled when designing RNA nanostructures. To expand the repertoire of molecular recognition in the P5abc/ΔP5 interface, we modified the interface by replacing the parent tertiary interactions in the interface with artificial interactions. The engineered P5abc/ΔP5 interfaces were characterized biochemically to identify those suitable for nanostructure design. The new interfaces were used to construct 2D-square and 1D-array RNA nanostructures.
