An aptazyme is an aptamer-ribozyme combination with intrinsic RNA cleavage activity. This aptazyme is specific for the guanine (ligand).

This sequence corresponds to inactive aptazyme, this means that the ribozyme part is mutated and the aptazyme lost its capacity to cleave itself. iGEM Strasbourg 2019 used it as a negative control for the part: BBa_K2923003

Guanine inactif aptazyme

An aptazyme is an aptamer-ribozyme combination with intrinsic RNA cleavage activity. This aptazyme is specific for guanine and guanosine ligands. It is composed of 3 different parts: a ribozyme module, a communication module and an aptamer module. This sequence corresponds to inactive aptazyme: the ribozyme module is mutated and the aptazyme lost self-cleavage capability. iGEM Strasbourg 2019 used it as a negative control for the part: BBa_K2923003
