Design Notes

Suggested by Sri Kosuri and Drew Endy as a high efficiency terminator. The 5' end cutoff was placed immediately after the TAA stop codon and the 3' end cutoff was placed just prior to the RBS of Gene 1.4 (before AAGGAG). Subsequently mutations were introduced to make the terminator bi-directional (i.e., AAAAAA insertion on 5' side of the stem loop). Additional mutations were introduced on the 3' side of the stem loop to increase the number of T's and eliminate any promoter -10 site that might be present to avoid initiation of transcription of whatever is downstream.

The result was cretion of a promoter in the reverse direction.

Use anywhere transcription should be stopped when the gene of interest is upstream of this terminator and transcription should be initiated in the reverse direction.
