Part:BBa_K2923021

MS2-MS2-Guanine inactif aptazyme-PP7-PP7

Our bacterial three-hybrid (BH3) construct (inspired by Berry and Hochschild, 2018) is composed of two fusion proteins with MS2 and PP7 coat proteins and RNA. To make the interaction between BH3 and guanine aptazyme iGEM Strasbourg created an aptazyme bordered by MS2 and PP7 stem-loops. 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_K2923020
