Strand-Displacement
The strand-displacement mechanism uses competitive binding of two identical nucleic acid sequences, the competing strand and the switching strand. It is based on rational design and results in the disruption or restoration of the hammerhead ribozyme as a result of restoration in the aptamer domain.
competing strand
The competing strand is the nucleic acid sequence that is bound to the the general transmission region in the restored switch conformation in the presence of a ligand
switching strand
The switching strand is the nucleic acid sequence that is bound to the general transmission region in the disrupted switch conformation in the absense of a ligand
