PhlF gave 83-fold repression of GFP expression from PphlF (<bbpart>BBa_K1725000</bbpart>), whereas the control, TetR (<bbpart>BBa_C0040</bbpart>), gave only 33-fold repression of pL-tet (<bbpart>BBa_R0040</bbpart>). (figure 1) A lower expression level of PhlF completely represses GFP expression from PphlF, compared to the higher expression level of TetR required for pL-tet. (figure 2)

PhlF gave 83-fold repression of GFP expression from PphlF (BBa_K1725000), whereas the control, TetR (BBa_C0040), gave only 33-fold repression of pL-tet (BBa_R0040). (figure 1) A lower expression level of PhlF completely represses GFP expression from PphlF, compared to the higher expression level of TetR required for pL-tet. (figure 2)
