WebTogether, these results suggest that Ptet and Plac display a dynamic induction range of four orders of magnitude, making them the best controllable promoters currently available for S. pneumoniae. WebIn the composite part of ( BBa_K346085 ), T7 RNAP was expressed under the Ptet, which was registered in 2010. Here, the composite part of ( BBa_K346085 )was inserted into the genome of BL21 (DE3) (Fig. 2A), yielding the strain of BL21 (DE3)-tet. We used the pET-eGFP plasmid to characterize the leakage ability of the Ptet and the transcription ...
