T7 Promoter
T7 promoter for protein Expression. The promoter was used by the iGEM Team Heidelberg in the context of phage assisted continous evolution (PACE).
Usage and Biology
Contribution: New documentation from Evry_Paris-Saclay 2020
This part is the strong promoter from T7 bacteriophage (taatacgactcactata) with GGG of 3' end. The T7 RNA polymerase initiates the transcription at the first guanidine of this stretch of three G and it was shown that +1 GGG is one of the best +1, +2 and +3 base combinations at the transcription initiation for enhanced promoter strength [1].
