JT2 strain, genes from BioBricks and Dr. Jeff Tabor plasmids
Derived from Dr. Jeff Tabor JT2 E. coli strain, this part is a built-in red-light induction system in E. coli made through chromosome insertion. Avoiding the need of any extra-chromosomal DNA when light-inducing gene expression offering several advantages to the researcher. It is proposed as a photo-chassis that could make useful tools in this field of light induction. Integration was performed for the genes pcyA, ho1, Cph8 and a Mnt working as follows: Genes ho1 and pcyA are responsible for the chromophore synthesis. Cph8 codes for the chimaeric red-light receptor. These three genes are constitutively expressed. Mnt repressor is expressed from pOmpC promoter, which stops being induced in presence of red-light. It is therefore used as a NOT-gate to regulate expression from pMnt.
UANLBricks for assambly of photochassis. Dr. Kuhlman integration protocol.
Due to illegal sites it was implemented UANLBricks assambly
CDS was extracted by PCR, promoter and terminator were Classic BioBricks.
pcyA gene transcribed from constitutive promoter.
For the project that this part was made, it was needed to use other Assambly Standard.
ho1 gene transcribed from constitutive promoter.
Double terminator consisting of BBa_B0010 and BBa_B0012
constitutive promoter family member and RBS
Promoter: John Anderson. RBS: Vinay S Mahajan, Voichita D. Marinescu, Brian Chow, Alexander D Wissner-Gross and Peter Carr IAP, 2003.
Constitutive promoter (strong) with RBS (strong, efficiency=0.3)
Extracted by PCR from pPLPCB(S) plasmid of Dr. Jeff Tabor.
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.
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.
