cIts is expressed by the weak J23114 promoter and, at low temperatures (<37??C), inhibits PR. In this case, PtetR is active because TetR is not produced. At high temperatures, cIts is inhibited, PR is active and produces TetR, which inhibits PtetR.

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.

Built by Josh as an intermediate in screening plasmid construction.
Protein generator converting TIPS to the protein TetR. Used as the input section for Quad Part Inverter Q01140.
This device is identical to <partinfo>BBa_K098995</partinfo>, but contains the correct sequence of cIts. It has been submitted as a new part to fix sequence bugs.
cIts/PR-based heat-inducible device. The weak promoter J23114 drives the expression of cIts. At low temperature (<37??C) cIts represses PR (OFF state), while at high temperature cIts is inhibited and PR transcription is ON. For these reasons, this device can generate a transcriptional signal in a temperature-dependent fashion.

RBS (Elowitz 1999) -- defines RBS efficiency
Varies from -6 to +1 region from original sequence to accomodate BioBricks suffix. 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.

Varies from -6 to +1 region from original sequence to accomodate BioBricks suffix ("RBS-1" in figure 4-14 of thesis). No secondary structures are formed in the given RBS region.

Derived from luxICDABEG operon terminator of Vibrio fischeri <genbank>AF170104</genbank>.
Bidirectional transcriptional terminator consisting of a 22 bp stem-loop.
In the naturally-occuring sequence there is a mismatch in the stem of the stem loop. This can be corrected via an A->G mutation (at position 40 -- sequence coordinate/not MFOLD coordinate). The above sequence does not reflect this mutation (but the MFOLD image does). This terminator's location cannot be found using some inverted repeat detectors like PALINDROME because it is too short and contains a mismatch. This one was found with the help of Tom Knight. It lies between two coding regions that point towards eachother.

The cI regulated promoter is based on the pR promtoer from bacteriohage lambda. The promoter has two two DNA binding sites for lambda cI repressor <bb_part>BBa_C0051</bb_part>. cI binding results in repression of transcription. The specific sequence used here is based on the cI repressible promoter used in the Elowitz repressilator (and references therein).
In order to address concerns about the promoter transcribing in the reverse direction, we have removed the -35 and -10 signals responsible for the promoter activity in the reverse direction. (More details needed here! DE, 2/24/03) Incompatible with host expressing cI repressor.

tetracycline repressor from transposon Tn10 (+LVA)

Coding region for the TetR protein without the Ribosome Binding Site. Modified with an LVA tail for rapid degradation of the protein and faster fall time for the emission. TetR binds to the pTet regulator (BBa_R0040). aTc (anhydrotetracycline) binds to TetR and inhibits its operation.
