LasR protein without degradation tag under transcriptional control of PlasB promoter and reverse antisense PBad promoter, the RBS has a strength of 0.6 (obtained by Jason Kelly and Robbie Bryant during the summer of 2004 using a fluorescent reporter). This construct represents (in presence of N-(3-oxododecanoyl)homoserine lactone in the media) an auto-inducing loop in which the PlasB promoter drives expression of its own inducer LasR. The running loop can be turned off through activation of the reverse antisense PBad promoter by arabinose.
RBS.1 (strong) -- modified from R. Weiss
Strong RBS based on Ron Weiss thesis. Strength is considered relative to <bb_part>BBa_B0031</bb_part>, <bb_part>BBa_B0032</bb_part>, <bb_part>BBa_B0033</bb_part>.
Varies from -6 to +1 region from original sequence to accomodate BioBricks suffix ("orig" in figure 4-14 of Ron Weiss thesis). No secondary structures are formed in the given RBS region. Users should check for secondary structures induced in the RBS by upstream and downstream elements in the +50 to -50 region, as such structures will greatly affect the strength of the RBS.

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.
