BS_united China 2023: we will use this binding region of EL222 to synthesize a blue light suicide system that will start when our engineering bacteria lost in the external environment is not exposed to blue light. Because our engineering E. coli will be killed during the absence of blue light, namely in the dark or at night, we equipped our engineering bacteria with a special part to produce EL222, a light-regulated DNA-binding protein. This protein can harness blue light to drive the reorientation of its Light-Oxygen-Voltage (LOV) sensory and Helix-Turn-Helix (HTH) effector domains, resulting in its self-dimerization and thus biding to the EL222 binding region located in between −35 (TTGACA) and −10 (TATAAT) region of the luxI promoter. Therefore we used this part for EL222 to start CAS9 suicide system to ensure the safety of the environment.

BS_united China 2023: we will use this binding region of EL222 to synthesize a blue light suicide system that will start when our engineering bacteria lost in the external environment is not exposed to blue light. Because our engineering E. coli will be killed during the absence of blue light, namely in the dark or at night, we equipped our engineering bacteria with a special part to produce EL222, a light-regulated DNA-binding protein. This protein can harness blue light to drive the reorientation of its Light-Oxygen-Voltage (LOV) sensory and Helix-Turn-Helix (HTH) effector domains, resulting in its self-dimerization and thus biding to the EL222 binding region located in between −35 (TTGACA) and −10 (TATAAT) region of the luxI promoter. Therefore we used this part for EL222 to start CAS9 suicide system to ensure the safety of the environment. The detailed design of our team can be seen below:
