Hybrid promoter (cI and luxR regulated) and normal RBS cI lambda
Hybrid promoter (cI and luxR regulated) and normal RBS cI lambda. This is a composition of BBa_R0065 and BBa_P0451.
Ligation of BBa_R0065(SpeI and PstI) and BBa_P0451(XbaI and PstI).
Promoter (lambda cI and luxR regulated -- hybrid)
cI repressor negatively regulates this promoter and LuxR activates its transcription.The effect of cI is dominant over LuxR. This part is based on the LuxR and cI repressor regulated hybrid promoter designed and tested by Ron Weiss. It requires the binding of two cI repressor dimers for maximal repression and contains two cI repressor binding sites namely, OR1 and OR2. This promoter is leaky in the sense that 'some' transcription is seen in the absence of both cI and LuxR. LuxI cI activity of promoter + + zero + - maximum - + zero - - leaky (no quantitative information)
This part was designed based on the LuxR and cI repressor regulated hybrid promoter tested by Ron Weiss and the LuxR-LuxICDABE sequence annotated by Tom Knight <genbank>AF170104</genbank>.

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.

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.
cI repressor from E. coli phage lambda (+LVA)
Elowitz, M. B. Transport, Assembly, and Dynamics in Systems of Interacting Proteins. Thesis, Princeton Univ., Princeton (1999).
Coding region for the cI repressor based on cI repressor from bacteriophage lambda modified with an LVA tail for rapid degradation of the protein. cI repressor binds to the cI regulator (BBa_R0051).

It has been modified to include a rapid degradation LAA tail, and includes the BioBrick standard assembly head and tail restriction sites. The RBS has been removed. The stop codon has been changed from TAA to a double stop codon TAATAA.
