aiiA with degradation tag expressed under Plux-lambda hybrid promoter and a double terminator+ heat sensitive C1-lambda under constitutive promoter and a double terminator
We used aiiA ,Lambda-CI with Deg tags and after each part there was a double terminator.
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.

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.

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.

Coding region for the autoinducer inactivation enzyme A (aiiA) LVA tagged. The gene was originally isolated from Bacillus sp. 240B1 and it encodes an enzyme that catalyzes the degradation of N-acyl homoserine lactones (AHLs)--quorum sensing autoinducers.

This part is a promoter that was designed as a correction to the anomalous BBa_R0065 BioBrick. This part consists of a Lux Box binding site for the LuxR-C6HSL Complex; in addition, it contains two operator sites for the cI protein appropriated from the Lambda bacteriophage. Because basal expression without the LuxR-C6HSL complex present is expected to be minimal, and because the cI operator sites are positioned so as to block the critical -10 transcription initiation site on the promoter, if cI is high, the promoter is off; if AHL is low and cI is absent, the promoter is leaky; if AHL is high and cI is absent, the promoter is on.
This it the temperature sensitive cI from the PGW7 plasmid. It has the Elowitz RBS in front (BBa_B0034). It produces a temperature sensitive cI repressor that loses binding efficiency with the cI promoter between 35 and 42 degrees C.

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.
