In our design (Fig. 1), there are two independently inducible promoters (Ptac and pBAD) allowing for fine tuning of gene expression by modifying the amount of IPTG and arabinose. This device contains an improvement of the existing part of the device (BBa_K592019) because it constitutes a self-contained functional system with an improved RBS for PcpcG2 adapted from (16), suspected to increase the level of expression of the genes downstream of the promoter by about 40 times compared to the wild-type promoter.

Green Light Inducible bacteriocin Device (GLID)
We designed a ‘template’ green light-inducible device (GLID) with blue output (amilGFP), adapted from Synechocystis sp. PCC6803. There are three components of the system: the chromatic acclimation sensor (CcaS), the response regulator (CcaR) and the PcpcG2 promoter. CcaS is a histidine kinase which is activated by green light and can catalyze phosphorylation of CcaR, leading to its activation and induction of gene expression downstream of PcpcG2.
