Varies from -6 to +1 region from original sequence to accomodate BioBricks suffix. <p>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.

Coding region for the TetR protein without the Ribosome Binding Site. Modified with an LVA tail for rapid degradation of the protein and faster fall time for the emission. TetR binds to the pTet regulator (BBa_R0040). aTc (anhydrotetracycline) binds to TetR and inhibits its operation.</P>

This is a composite RNA element that could be repressed by targets of sRNA---spot42 as well as repress targets of spot42. It???s an artificial element for sRNA-sRNA interaction and facilitate our construct of RNA-mediated ratio sensor.

Spot42 is a multitarget small RNA that mediates the discoordinate expression of the E.coli galactose

Spot42 is a multitarget small RNA that mediates the discoordinate expression of the E.coli galactose operon and other sugar metabolic pathway,such as galK,nanC,ytfJ,srlA,which are the 5??? leader sequence of the corresponding metabolic enzymes.
Take galK for example,Spot42 causes translation repression by base pairing to RBS in the 5??? leader sequence,then block the recognition of the antiSD sequence on 30S subunit.
It???s a very strong pairing(up to 20bases),but it only causes 2.6 fold repression according to Johannes H. Urban and Jo?? rg Vogel,for it doesn???t result in the degradation of the RNA complex by RNaseE(ssRNA degradation) and RNaseIII(dsRNA degradation),both of them are major enzymes that causes RNA degradation in vivo.Spot42-galK complex degrades in a slow and presently unclear way. The base pairing is initiated by the recognition of seed region,which plays a significant role in the repression efficiency.
Small RNA chaperone Hfq is an abundant protein that has 40000~50000 copies each cell,accelerating annealing and strand-exchange between small RNAs and target mRNA.Hfq binds to the AU-rich domain of small RNA,and footprinting experiments has shown that Hfq protects the degradation of RNA from RNase.It is essential to most of small RNAs in E.coli,extremely enchances the repression efficiency.
Spot42 have a weak Hfq binding site(whereas galK weaker),an endogenous terminator(unclear efficiency,maybe weak),and the multitarget repression stem-loop.

<P> <P>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).<P> Use anywhere transcription should be stopped when the gene of interest is upstream of this terminator.

Inverting regulatory region controlled by LacI (<bb_part>BBa_C0010</bb_part>, <bb_part>BBa_C0011</bb_part>, etc.) <p> The PLlac 0-1 promoter is a hybrid regulatory region consisting of the promoter P(L) of phage lambda with the cI binding sites replaced with lacO1. The hybrid design allows for strong promotion that can nevertheless be tightly repressed by LacI, the Lac inhibitor (i.e. repressor) (<bb_part>BBa_C0010</bb_part>) ([LUTZ97]). The activity of the promoter can be regulated over a >600-fold range by IPTG in E.Coli DH5-alpha-Z1 (same paper reference).

<P> <P>hybrid promoter design to create strong promoter that is, at the same time, highly repressible. note that the upstream operator installed in this hybrid is slightly different than the one in the original source (Lutz and Bujard, 1997). the most upstream operator region is slightly truncated in the represillator version, so that both operators in the hybrid are the same sequence. see references for details. also, the sequence has been truncated after the transcriptional start site.<P>LacI binds to this regulator. This part is incompatible with species containing active LacI coding regions. Lactose and IPTG disable the operation of LacI and increase transcription. This part is incompatible with environments containing lactose or lactose analogs.
