Lux promoter from oligo DNA, M13 genes and origin from BBa_K1139019, GFP from BBa_E0040, rbs from BBa_B0030, double terminator from BBa_B0015 are combined.
M13 is a filamentous phage that infects only F+ strains of E. coli, which does not kill the host cell. This biobrick is derived from M13mp18 phage vector by PCR. It inclueds 11 ORFs, M13 origin, a packaging sequence and Lac promoter. The promoter on the upstream of g2(gene 2) is altered to Lux promoter. A phage particle is formed only when the host cell receives AHL signal(3OC6HSL, C6) because g2p(gene 2 protein) is an endonuclease needed for a plasmid to be replicated by M13 origin, and to be packaged into the phage particle. As a reporter, GFP is inserted on the downstream of the Lac promoter.
RBS.1 (strong) -- modified from R. Weiss
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. 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.

Promoter (luxR & HSL regulated -- lux pR)
Promoter activated by LuxR in concert with HSL 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 LuxR activator protein complexed with the autoinducer, 3-oxo-hexanoyl-HSL. Two molecules of LuxR protein form a complex with two molecules of the signalling compound homoserine lactone (HSL). This complex binds to a palindromic site on the promoter, increasing the rate of transcription.
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. <img src="<bb_file>Image1.gif</bb_file>" width="614" height="362">

Double terminator consisting of BBa_B0010 and BBa_B0012
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.
