MS2-MS2-Guanine actif 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 protein and RNA. To make the interaction between BH3 and guanine aptazyme iGEM Strasbourg created an aptazyme bordered by MS2 and PP7 stem-loops. This aptazyme is specific for the guanine or guanosine ligand. It is composed of 3 different parts: a ribozyme module, a communication module, and an aptamer module. This aptazyme is an ON-switches type of aptazyme. Its catalytic activity (self-cleavage) requires the presence of ligand.
