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.

Sequence for pTet inverting regulator driven by the TetR protein.
BBa_R0040 TetR-Regulated Promoter is based on a cI promoter. It has been modified to include two TetR binding sites and the BioBrick standard assembly head and tail restriction sites.

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.

From Regestry: BBa_B0015 BBa_I13521 Lox Sites: Zuwen Zhang and Beat Lutz (2002) Cre Recombinase-mediated inversion using lox66 and lox71: method to introduce conditional point mutations into the CREB-binding protein NUCLEAIC ACIDS RESEARCH
This part is designed to be placed downstream of a promoter and prevent any Pops from the Promoter passing through this part. It will do this until an accompanying Cre Recombinase plasmid becomes activated. Once the Cre recombinase is activated the enzyme produced will permanently cut a section of DNA from the plasmid containing this part. This short section of DNA contains stop codons so once these are removed the polymerase can pass through this part and transcribe downstream genes. This short section of DNA is degraded. This is useful if a component of the system must be grown up but not activated until a certain external stimulus is added such as a positive feedback loop. This part should be very efficient at preventing Pops passing through it. The Part also contains a RFP reporter which is transcribed in the 3???-5??? direction. This means that un-activated parts will fluoresce red and activated parts will not fluoresce. This allows you to see that the part is working in your system. It also allows you to observe the efficiency of activation of the part in your system. Because of the way Cre recombinase works the excised reporter will remain in a small plasmid and continue to be transcribed for a short time however this plasmid will not have an origin of replication so will not be copied and the fluorescent protein should stop being produced after around 15min The design uses mutated lox sites, lox66 and lox71, which will make the excision irreversible.
