Nitrate responsive promoter with BamH1 production for safety
This part is composed of pre-existing biobrick parts. The BamH1 was submitted by the UC Berkeley 2007 team.
This part contains the PyeaR-RFP cassette with the BamH1 coding region under an Arabinose inducible promoter to trigger the death of the bacterium.
Double terminator consisting of BBa_B0010 and BBa_B0012
This part is in biobricks 2.0 with BamHI and BglII sites instead of PstI and SpeI sites
All parts of this construct are from previously submitted biobricks.
PyeaR is a nitrate responsive promoter driving a red fluorescent protein reporter.
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.
PoPS in -> RFP out Strong RBS (efficiency=0.6). Artificial 39 bp terminator (efficiency=0.99).
PyeaR promoter, responsive to nitrate, nitrite and nitric oxide
BioBricked from E. coli K-12 genomic DNA by the Edinburgh 2009 iGEM team.
PyeaR promoter. This is the promoter of the Escherichia coli yeaR/yoaG operon (see Lin, H.-Y., Bledsoe, P.J., and Stewart, V. 2007. Activation of yeaR-yoaG operon transcription by the nitrate-responsive regulator NarL is independent of oxygen-responsive regulator Fnr in ''Escherichia coli'' K-12. J. Bacteriol. 189, 7539-7548). Unlike other E. coli promoters responding to nitrate and nitrite, this promoter is not repressed under aerobic conditions.
**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.
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.

modified E. coli thr terminator, replaced all A-T pairs in stem with C-G pairs
Artificial terminator, estimated %T~>90% *8bp stem, 6nt loop *Bidirectional, estimated reverse %T~>90%
Bidirectional, with the reverse estimated to be less effective than the forward. Has a polyA tail of 9 residues.
