tetracycline resistance protein TetA(C) (backwards) [cf. BBa_J31007]
This is the coding region for Tetracyline resistance in the reverse orientation. If a promoter adn RBS are placed downstream and the entire region, from promoter to stop codon is flipped the cell will express tetracycline resistance.
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.

V. fischeri <genbank>AF170104</genbank>
Synthesizes 3OC6HSL, which binds to LuxR. The lux cassette of V. fischeri contains a left and a right promoter. The right promoter gives weak constitutive expression of downstream genes.This expression is up-regulated by the action of the Lux repressor, LuxR. Two molecules of LuxR protein form a complex with two molecules the signalling compound HSL. This complex binds to a palindromic site on the promoter, increasing the rate of transcription.
An LVA tail (sequence: AANDENYALVA) was added to increase protein degradation. .

In complex with HSL, LuxR binds to the Lux promoter, activating transcription from Pr <bb_part>BBa_R0062</bb_part>, and repressing transcription from Pl <bb_part>BBa_R0063</bb_part>. The lux cassette of V. fischeri contains a left and a right promoter. The right promoter gives weak constitutive expression of downstream genes.This expression is up-regulated by the action of the Lux activator, LuxR complexed to HSL. Two molecules of LuxR protein form a complex with two molecules the signalling compound homoserine lactone (HSL). This complex binds to a palindromic site on the promoter, increasing the rate of transcription.
2 silent point mutants were introduced in the coding sequence to remove internal XbaI and PstI sites. Mutation sites were chosen to replace codons commonly used in E. coli with codons used at a similar frequency.
The sequence of the LasI upstream regulatory region is available at http://www.pubmedcentral.nih.gov/articlerender.fcgi?artid=176640
This pLas' promoter contains the regulatory region upstream of the LasI gene in Pseudomonas aeruginosa. K091117 includes a LasR binding site as well as a -10 region modified from CATAAA to TATAAA to reflect our pLasXOR promoter design. Activation is expected to occur in the presence of the autoinducer PAI-1 and the LasR protein. The pLas' promoter serves as a control for the evaluation of the pLasXOR promoter, part BBa_K091118.
To minimize leaky transcription, a secondary transcriptional start site was excluded from the design.
