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.

Produces LuxR protein which can sense 3OC6HSL in the media and activate transcription from R0062, the right hand Lux promoter
autoinducer synthetase for N-butyryl-HSL (BHL) and HHL
Autoinducer synthesis protein that produces N-butyryl-HSL which binds to RhlR, obtained from Pseudomonas aeruginosa.
Editing Check (1/28/04) (0) BB sites cleaned (1) ATG (2) TAATAA (3) Blast checks out (i.e., it's RhlI) (4) Codon changes OK (AA and tRNA usage) (5) Chassis might have conflict (w/ native autoinducer system?) (6) ssrA tag added (7) barcode added (8) Codon optimized for expression in enteric bacteria 2 silent point mutations have been included into the sequence at base 138 from A to G and at base 576 from G to C to remove internal EcoRI and PstI sites. Mutations were chosen to yield the same amino acid and codons of similar frequency in E. coli.

Promoter (luxR & HSL regulated -- lux pL)
The lux cassette of V. fischeri contains a left and a right promoter. The left promoter gives weak constitutive expression of downstream genes.This expression is down-regulated by the action of the Lux repressor, LuxR. 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 from Pr, repressing transcription from Pl
This promoter is based on the Vibrio fischeri quorum sensing gene promoters. Two genes LuxI and LuxR and transcribed in opposite directions as shown below. The original sequence from which the parts <bb_part>BBa_R0062</bb_part> and <bb_part>BBa_R0063</bb_part> were derived is shown in the picture below.Includes most of Lux reulatory region, including the LuxR binding site which activates the right promoter. A putative LuxR autorepression binding site is also identified adjacent to the -10 site of the right promoter. This 2nd site has 55% identity with the first site. Putative inverted repeats (of size 18-27 bp) also exist between these two sites (not marked above), which may represent binding sites for other regulatory proteins. <img src="<bb_file>Image01.gif</bb_file>" width="614" height="362"> Unspecified.

B0034.E0034.B0015 output device with aav tagged yfp
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.
V. fischeri <genbank>AF170104</genbank>
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.
