Herein we studied the role of the AT-rich region upstream of -17 in transcription regulation of T7 RNA polymerase. Equilibrium DNA binding studies with promoter fragments of consensus sequence truncated at various positions between -17 and -27 showed that the polymerase-promoter complex is ...

(bio-dsDNA) containing aT7 promotersequence, and Cas13a was used in a dual functional manner to enhance signal amplification by T7 RNApolymerasetranscription and to induce thetrans-cleavage activity. The bio-dsDNA was adopted instead of the bio-RNA because of the big size of Cas13, which ...
reported here indicate that an A + T-rich region that overlaps the upstream end of the promoter has an important role in the control of promoter selection during T7 infection. In addition, changes in the 23-bp conserved promoter sequence may also affect promoter regulation....
regulation of T7 RNA polymerase. Equilibrium DNA binding studies with promoter fragments of consensus sequence truncated at various positions between -17 and -27 showed that the polymerase-promoter complex is significantly stabilized as the upstream AT-rich sequence is extended to and beyond -22. ...
Here, we use 5′RACE-Seq to screen a randomized initially transcribed region of the T7 promoter for cross-talk with transcriptional activity. We reveal that sequences from position +4 to +8 downstream of the transcription start site affect T7 promoter activity over a 5-fold range, and...

1, we did not know which promoter (if any) will outperform the WT, so the name T7Max was not yet assigned to any sequence. For clarity, to avoid having the same sequence under two different names, we use label T7Max on all figures. Next, we proceeded to test full translation ...
