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.

Anything inserted into the NheI shouldn't have a start codon and gene should still be in frame.

Generic Surface Display Construct: IPTG Inducible Lpp + 1tmr OmpA + NheI Site
2009-09-29T11:00:00Z
2015-05-08T01:11:30Z
The Lpp + 1tmr OmpA is from Havard iGEM 2006: BBa_J36848, which is from [cite].
This is a generic surface display construct that displays a protein with the OmpA surface display system as described in [cite].
To insert a gene, you will need to design a primer that removes the start codon and adds a XbaI site that keeps the rest of the gene in frame with OmpA. This assumes that the gene is a biobrick with the standard suffix following the gene. If you are creating the gene from scratch, biobrick it then follow this guide so that there is the standard suffix following the gene.
For example, assume our gene (E0040) starts with:
5'-atgcgtaaaggagaagaacttt...-3'
The design process would be:
1. Start with the XbaI site: 5'-TCTAGA-3'
2. Add ~20bp of the gene immediately after the XbaI site, starting _after_ the start codon (atg), and try to end on a G or C: 5'-TCTAGAcgtaaaggagaagaacttt-3' for E0040 from above. These ~20bp will determine the melting temperature for the primer.
3. Add 6-8 random nucleotides at the start. Try to balance out the primer to ~%50 g&c to a&t: 5'-cgggcTCTAGAcgtaaaggagaagaacttt-3'
4. Tweak the number of nucleotides until the melting point roughly matches that of Vr.
Then to add the gene to the construct, again assuming the gene is a biobrick with standard suffix:
1. PCR with the designed forward primer and Vr
2. Then run the PCR product in a digest with XbaI and PstI, and digest this part (the display construct) with NheI and PstI. The XbaI site has a sticky end that binds with NheI.
3. Standard ligation and transformation.

Promoter (lacI regulated, lambda pL hybrid)

represillator of Elowitz and Leibler (2000)
Released HQ 2013
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.
