The promoter is on normally, and off when the PhlF repressor (K1725041) is bound to it. We measured the strength of the promoter with GFP and two different ribosome binding sites (B0032 and B0034), and compared to R0040 and K1725020.

PhlF repressible promoter

This promoter was characterised by driving expression of GFP with two different Ribosome Binding Sites, as found in the BioBricks E5501 and I13500.

GFP fluorescence of K1725001, K1725002, K1725021, K1725022, K1725082, and E5504 with plasmid backbone pSB3K3 was measured to compare the relative strengths of promoters K1725000 and K1725020 to a promoter already well documented in the registry, R0040. Figure 3 shows the fluorescence scan image and a graph of approximate molecules of GFP per cell. These results indicated that K1725000 is a significantly stronger promoter than R0040 or K1725020. It also further confirms that B0034 is a stronger ribosome binding site that B0032.
