LasR/LasI Inducible (RHLR/RHLI repressible) positive feedback production of 3OC12 HSL
For source of the promoter see j64712. The rest of the parts existed in the registry already.
This construct will produce more 3OC12 HSL when the circuit is given an inital amount of 3OC12 and when LasR is present in the system. This construct will also produce RFP as a reporter when expressed.
LasR/LasI Inducible & RHLR/RHLI repressible Promoter
Rust L. et. al., "Analysis of the Pseudomonas aeruginosa Elastase (lasB) Regulatory Region". Journal of Bacteriology, 1996.
This part is similar to BBa_R0079 but has an added binding site for RHLR/RHLI in between the -35 and -10 region. Thus this promoter is induced by LasR/LasI but repressed by RHLR/RHLI binding.
The natural spacer between the -35 and -10 is 14bp and the natural O1 site for RHLR/RHLI is 20bp long. There was not much over lap of the -35 or the -10 with this sequence, so it was nessicary to chop off some of the binding site sequence in order to maintain the correct spacing and preserve the -35 and -10 sequence. The binding site sequence is missing a tcc on is 5' end and a t on its 3' end.
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.

**highly** engineered mutant of red fluorescent protein from Discosoma striata (coral)
Campbell et al., PNAS v99 p7877 URL
monomeric RFP: Red Fluorescent Protein. Excitation peak: 584 nm Emission peak: 607 nm
TAATAA double stop codon added (DE). Four silent mutations made to remove three EcoRI sites and one PstI site: A28G, A76G, A349G, G337A.
Double terminator consisting of BBa_B0010 and BBa_B0012
autoinducer synthetase for PAI from Pseudomonas aeruginosa (no LVA)
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.
