Nitric Oxide Sensing Genetic Circuit With One Ribosomal Binding Site

This composite part consists of the inducible pNorVβ promoter (BBa_K4387000), superfolder GFP preceded by one strong ribosomal binding site (BBa_B0034, BBa_K2553008), the NorR regulator (BBa_K4387001), and a double forward (BBa_B0015). We chose a high-copy backbone from Twist for this part. Due to the competitive binding of the activated and inactivated NorR on the promoter, we decided on this construct with a positive feedback loop that adjusted the levels of NorR. The presence of nitric oxide would activate PnorV_beta to induce GFP and NorR expression. Thereby, we ensure that high amounts of NorR will be produced in the presence of NO and in the presence of NO only.
