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.


 

Fluorescence assay of CcaS-CcaR system with PcpcG2-238 and PcpcG2-172 in CL1 (△EnvZ), and PCB (△CcaS) as chromophore.

 

Leaked expression in darkness significantly reduced after truncation of the constitutive promoter. By the way, the difference of fluorescence under green and red light is narrowed unexpectedly.
