Randomly generated and optimized for several parameters (see Design notes).
Released HQ 2013
Generic spacer for ensuring a 70 bp distance between the end of the suffix of the BioBrick part containing the double terminator and the prefix of the BioBrick part containing the promoter of the new gene. Please, use the AlignX function of Vector NT to check for homology with the components in your plasmid before using this spacer.</P>

<P> <P><p>The size of the spacer was choosed to meet the minimum length of a sequence that can be queried using the BLAST search engine. However, subsequences of it can be used to design shorter spacers. The sequence was selected from many more sequences randomly generated using the <a href="http://www.lifesci.ucsb.edu/~maduro/random.htm">Random DNA Generator </a>engine; the GC% parameter used as input was 50%. The sequences were selected based on the following constraints listed in their order of importance: the absence of any putative promoter regions, a low degree of homology with the Elowitz plasmid (whose components are widely used in our designs), no homology with other <em>E.coli</em> sequences as shown by BLASTN search results and the presence of a number of TAA stop codons. The second constraint was the most stringent leading to the elimination of most sequences. </p> <p> DE made the following changes to the original sequence in order to add stop codons in the -3 frame and more in the +2 frame (note, not all of these stop codons are UAA. Thus, if used in an organism that inserts an amino acid @ UGA or UAG the obvious will occur):<br> T->A @ 85<br> T->A @ 42<br> C->T @ 79<br> A->T @ 64<br> A->T @ 31<br> T->A @ 34<br> C->A @ 37<br> Also, note that the above changes further reduce (the already very weak) homology to current NCBI-stored sequences.<br> </p> <P>In the process of selecting the best sequence it appeared that a good alternative sequence for a spacer would be: AGGTTCTGATATGTAACTGTGCCCAATGTCGTTAGTGACGCATACCTCTTAAGAGGCCACTGTCCTAACA. The sequence contains no putative promoters and shows moderate homology with the 5' end of the Ampicillin resistance gene. However a strong promoter sequence starts 12 bp downstream of this sequence, and therefore the sequence presented above was preferred. </p><P> The sequence is compatible (does not show significant homology) with the components in the Elowitz repressilator plasmid.

d2' (RNA scaffold)
2012-05-31T11:00:00Z
2015-05-08T01:14:03Z
Delebecque et al, Science 2011.
Encodes for the first part of a 2-dimensional self-assembling RNA scaffold.
d2' is a sequence followed by the PP7 binding domain. The 2D RNA assembly D2 forms from d2' and d2'', each followed by a distinct PP7 and MS2 aptamer. The dormant tile d2' spontaneously generates the pro-tile d2-1, which interacts with d2'' to generate tile d2-2. d2-2 then self-assembles into the 2D RNA scaffold D2 with PP7 and MS2 binding domains.

The rhamnose-inducible promoter is described in Giacolone et al., Biotechniques 2006. We used bases
1951-2101 from BBa_K564001.
This is a rhamnose-inducible promoter. We used bases 1951-2101 from BBa_K564001. It is induced by 1000 micromolar rhamnose.

The riboswitch was inserted into the scaffold sequence directly upstream of the aptamer. Spacers were used to prevent folding issues with the scaffold and ribozyme components of the transcripts.
