cI without degradation tag under transcriptional control of Prm promoter and reverse antisense lasB promoter, the RBS has a strength of 0.3 (obtained by Jason Kelly and Robbie Bryant during the summer of 2004 using a fluorescent reporter). This construct represents an auto-inducing loop in which the Prm promoter drives expression of its own inducer cI. The running loop can be turned off by activating the reverse antisense lasB promoter (through LasR protein in the presence of Pseudomonas autoinducer (PAI))
We decided to keep PAI concentrations in the media constant (by adding N-(3-oxododecanoyl)homoserine lactone) and control the expression of LasR protein in order to achieve tight control of the reverse antisense lasB promoter.

Double terminator consisting of BBa_B0010 and BBa_B0012
Modified lamdba Prm promoter (repressed by 434 cI)
Lamdba Prm promoter modified to be activated by lamda repressor (cI) and repressed by 434 repressor (cI)
The O-R1 region of 434 contained 14 base pairs as opposed to the 17 base pairs of the O-R3 site of lambda. Also, it was noticed that the O-R3 site of the lambda included part of the -10 site. Hence, to preserve the spacing and the -10 site, the three nucleotides that were in both the -10 site and the lambda O-R3 site were retained. The 14 nucleotides that were in the O-R3 site and not in the -10 site were replaced with the O-R1 site of the 434.
Derived from the TE terminator of T7 bacteriophage between Genes 1.3 and 1.4 <genbank>V01146</genbank>.
Transcription terminator for the E.coli RNA polymerase.
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). Use anywhere transcription should be stopped when the gene of interest is upstream of this terminator.
Transcriptional terminator consisting of a 64 bp stem-loop.
