PcpcG2-172, a modified PcpcG2 promoter

PcpcG2 promoter is a 238bp green-light activated promoter in Synechocystis PCC 6803(Part:BBa_K592003). The full length promoter is comprised of a G-box region, a CcaR-P activated promoter, and a constitutive promoter, which contributes to the leakiness under red light and low dynamic range. Therefore, we constructed PcpcG2-172, a 172bp truncated cpcG2 promoter deleted for the constitutive promoter.(For more detail, please view our wiki: "http://2016.igem.org/Team:HZAU-China/Experiments" )

 

Figure 1. Fluorescence assay of CcaS-CcaR system with PcpcG2-172 (BBa_K2012015) in CL1 (△EnvZ), and PCB (△CcaS) as chromophore.

Fluorescence under green light is 1.81-folds of red light, proving that green light activates output expression, the device works well. PcpcG2-172 shows high efficiency.
