Modified T7 Promoter
This is the the T7 promoter BBa_J64997 with a single base pair (G) added to the 3' end.
Usage and Biology
Contribution: New documentation from Evry_Paris-Saclay 2020
This part is the strong promoter from T7 bacteriophage (taatacgactcactata) with GGG at 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].
