Neon lux positive feedback device with luxpR-HS promotor
This construct is the NEON positive feedback device, containing constantly expressed luxR, lux pR-HS (K2258001) controlled luxI, and lux pR-HS (K2258001) controlled GFP. Without AHL stimulation, the lux pR-HS promotor is repressed by the dCas9-gRNA expressed by Safety Catch system. Therefore, the luxI and GFP cannot be expressed. Upon the stimulation of AHL, the CRISPRi system in Safety Catch is inhibited, thus the lux pR-HS promotor is exposed, and then luxR-AHL complex now can bind and activate lux pR-HS promotor. Thereofre, luxI and GFP can now be expressed. Besides, this system will keep producing more luxI-AHL, which will form a positive feedback and increase the expression of GFP.
