Part:BBa_K4242012

Pci+Ppel+RBS+gfp+TT(pHYD-2)

Uses factors Pci(BBa_R0051) and Ppel(BBa_K4242001), strong RBS(BBa_J34801), gfp coding region(BBa_E0040), and TT(BBa_B0015). This part is an easy factor assessment tool. The gfp reporter enables you to find out whether the tandem factor PcI/pel works.

Usage and Biology

During our test of the pHYD-1 (BBa_K4242011), we found that promotor Ppel doesn’t work well in many organisms. To overcome this difficulty, we designed a tandem promoter PcI/pel in which the transcription start site of the constitutive promoter PcI is immediately followed by the FleQ binding site of the promoter Ppel. Transcription of the reporter gene gfp is promoted by cI promoter in the absence of FleQ. We found that the fluorescence of recombinant E. coli/pHYD-2 and S. oneidensis/pHYD-2 was drastically higher than that of the strains harboring pHYD-1 (BBa_K4242011), indicating that the tandem promoter is capable of constitutively promoting gfp expression in the absence of FleQ in both strains.
