Applications of BBa_R0061
BS_United_China 2023: we utilized this part to create our blue light suicide system, which is a system that will start when our engineering bacteria lost in the external environment is not exposed to blue light. This region of luxI promoter will be used in our design, where the EL222 binding region is located between −35 (TTGACA) and −10 (TATAAT) regions of the luxI promoter. In this way, once blue light is undetectable by EL222, the formation of EL222 dimers is terminated and the RNAP is allowed to bind back to the -35 to -10 region of the luxI promoter. This thereby activates the expression of CAS9 and its sgRNA sequence. The gene editing process takes place after that, disrupting two of the most crucial parts of the bacterial cell’s metabolic pathways, energy and protein production, which eventually cause the death of bacteria. The detailed design is showcased below:

In order to characterize R0061, Plux repression promoter, we constructed K395101 combining R0061 and K121013, which is a promoter-less gfp reporter (rbs-gfp-ter-ter) on pSB6A1 and used a fusion of PlacIq (I14032) to gfp (K121013) as a positive control and used promoterless gfp (K121013) as a negative control. |

Results![]() Figure. Fluorescence of GFP under lux repression promoter with/without AHL. p.c. stands for positive control, n.c. stands for negative control. All biobricks are co-transformed with K396011 (constitutive luxR generator). Bar heights are normalized to OD600 and represent the averages of three replicates; error bars, standard deviations.
