ToxR'::scFv Fusion 1 (with promoter and rbs and terminator)
The first of three fusions between ToxR', a modified dimerizing protein, and an anti-fluorescein binding scFv sequence. ToxR', active as a dimer, binds to the ctx promoter sequence (BBa_J07007) to initiate transcription. This part is designed to respond to a fluorescein dimer and activate the ctx promoter. The restriction sites flagged below were introduced to allow for protein fusions, and are not to be removed. See ToxR' (J07009) for details.
Substantial Energetic Improvement with Minimal Structural Perturbation in a High Affinity Mutant Antibody
single chain Antibody fragment selected to bind to fluorescein molecules. This scFv is the weakest of the three specified sequences. DNA insert in the pCT-4-4-20 (also known as pcT-302) from NheI to XhoI

Sequence for pTet inverting regulator driven by the TetR protein.
BBa_R0040 TetR-Regulated Promoter is based on a cI promoter. It has been modified to include two TetR binding sites and the BioBrick standard assembly head and tail restriction sites.

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.
Transcriptional terminator consisting of a 64 bp stem-loop.
