Part:BBa_K4195180

Biology

This sequence is a conserved region of toxin gene pirB.^[1]It’s used as the detection target of RENDR system.
Ribozyme ENabled Detection of RNA (RENDR)
RENDR is a high-performing, plug-and-play RNA-sensing platform. RENDR utilizes a split variant of the Tetrahymena thermophila ribozyme by synthetically splitting it into two non-functional fragments. Two fragments are each appended with designed RNA guide sequences, which can interact with the RNA input of interest. The split ribozyme is then inserted within a desired gene output. When binded with the RNA input, two transcribed split ribozyme fragments are triggered to self-splice and thus the intact transcript of the protein output will form.

Usage and Design

This part is used as the target of the detection system BBa_K4195187、BBa_K4195188、BBa_K4195189 and BBa_K4195190. We build the circuit similar as BBa_K4195178.
