Used BioBricks

This is a list of all BioBricks we used from the registry or created by ourselves and a short explanation, why we used them. The list is sorted alphabetically.

BioBrick (name and partnumber) Status Comment
double terminator, <partinfo>B0017</partinfo>: <partinfo>B0017 SpecifiedComponents</partinfo> from registry

This is a double terminator which contains two <partinfo>B0010</partinfo> terminators. We used this double terminator instead of the commonly used <partinfo>B0015</partinfo> double terminator (which was assembled from the <partinfo>B0010</partinfo> and the <partinfo>B0012</partinfo> terminator) because of problems mentioned in the partsregistry with the <partinfo>B0012</partinfo> terminator.

RBS, <partinfo>B0034</partinfo>: <partinfo>B0034 SpecifiedComponents</partinfo> from registry

The strong ribosomal binding site (RBS) AGGAG was always assembled.

lacI gene, <partinfo>C0012</partinfo>: <partinfo>C0012 SpecifiedComponents</partinfo> from registry

This is a gene for the lac repressor lacI with a LVA degradation tag. We used this BioBrick to build a tightly regulated lac-operon <partinfo>K389050</partinfo> with low basal transcription. It seems that this lacI is either degraded too quickly or it does not work properly because it is not possible to repress the lac operon with this part.

mRFP, <partinfo>E1010</partinfo>: <partinfo>E1010 SpecifiedComponents</partinfo> from registry

This BioBrick was used as a reporter gene, e.g. in the construct <partinfo>K389013</partinfo>. mRFP as a reporter gene has the advantage that it is easy to measure and comparatively stable.

lacIq promoter, <partinfo>I14032</partinfo>: <partinfo>I14032 SpecifiedComponents</partinfo> from registry

This promoter is a strong constitutive promoter which is natively located upstream of the lacI gene in E. coli lacIq strains. It was used to build a tightly regulated lac-operon <partinfo>K389050</partinfo> in which it was assembled upstream of the lacI gene from the partsregistry <partinfo>C0012</partinfo>.

sensitivity tuner, <partinfo>I746370</partinfo>: <partinfo>I746370 SpecifiedComponents</partinfo> from registry
  • sensitivity tuner 1...
sensitivity tuner, <partinfo>I746380</partinfo>: <partinfo>I746380 SpecifiedComponents</partinfo> from registry
  • sensitivity tuner 2...
sensitivity tuner, <partinfo>I746390</partinfo>: <partinfo>I746390 SpecifiedComponents</partinfo> from registry
  • sensitivity tuner 3...
mRFP generator, <partinfo>J04450</partinfo>: <partinfo>J04450 SpecifiedComponents</partinfo> from registry

This BioBrick was used as a visible selection marker for cloning other BioBricks into the <partinfo>pSB1C3</partinfo> plasmid to submit them to the registry. The promoter in this mRFP generator is pretty strong so it is easy to separate colonies which carry this BioBrick from colonies which do not carry this BioBrick anymore.

constitutive promoter, <partinfo>J23110</partinfo>: <partinfo>J23110 SpecifiedComponents</partinfo> from registry

This medium strong constitutive promoter from the registry was assembled before our BioBricks, so they are neither expressed too strong, so the cell suffers from metabolomic stress, nor too weak, so there is no visible effect of our BioBricks. This BioBrick was used e.g. in <partinfo>K389010</partinfo> or <partinfo>K389011</partinfo>.

R6K origin, <partinfo>J61001</partinfo>: <partinfo>J61001 SpecifiedComponents</partinfo> from registry

This BioBrick was used to create a plasmid without ColE1 ori. The R6K ori has a different compatibility class than the ColE1 ori. So it is used for a two plasmid screening system. The R6K ori is a medium copy plasmid in pir+ / pir116 E. coli strains like EC100D but it does not replicate in pir- strains like E. coli TOP10. So it is easy to separate a ColE1 ori plasmid from another with R6K ori by simply transforming both to e.g. E. coli TOP10.

virA, <partinfo>K238008</partinfo>: <partinfo>K238008 SpecifiedComponents</partinfo> from registry, fixed

We wanted to use this virA BioBrick from the registry but problems occurred (BioBricks/Tests), so we created our own virA from Agrobacterium tumefaciens C58 TI-plasmid. Our own (working) virA has the partnumber <partinfo>K389001</partinfo>.

vir-promoter, <partinfo>K238011</partinfo>: <partinfo>K238011 SpecifiedComponents</partinfo> from registry, fixed

The same problems occurred as with the virA BioBrick - this one from the registry does not work properly, so we made a vir-promoter by ourselves (<partinfo>K389003</partinfo>). The part that was sent to us is actually a tetR gene (<partinfo>C0040</partinfo>) under the control of a constitutive promoter (<partinfo>J23105</partinfo>) before a double terminator (<partinfo>B0015</partinfo>, compare our sequencing results).

virA, <partinfo>K389001</partinfo>: <partinfo>K389001 SpecifiedComponents</partinfo> new

The VirA receptor is used by A. tumefaciens to detect acetosyringone and other phenolic substances which are secreted by plants after injury. In presence of these substances VirA phosphorylates itself and afterwards VirG, a response regulator which activates vir promoters. These promoters control genes which are used for infecting the injured plant. This virA gene was isolated from the TI-plasmid of A. tumefaciens C58. An illegal PstI restriction site was removed by site-directed mutagenesis. The functionality of this BioBrick was prooved with <partinfo>K389015</partinfo> and <partinfo>K389016</partinfo>.

mutated virG, <partinfo>K389002</partinfo>: <partinfo>K389002 SpecifiedComponents</partinfo> synthesized, new

This is the VirG response regulator from the VirA/G receptor system. The VirA/G receptor system is used by A. tumefaciens to detect phenolic substances secreted by injured plants, e.g. acetosyringone. In presence of these substances, VirG is activated by the VirA receptor and induces the transcription of genes under the control of a vir promoter. Normally, VirG needs the rpoA gene (RNA polymerase subunit) from A. tumefaciens to work in Escherichia coli but this virG BioBrick is mutated, so it works with the rpoA subunit from E. coli. For this reason the point mutations G56V and I77V were brought into the gene (compare YC Jung et al., 2004). Because this BioBrick is synthesized (Mr.Gene GmbH), codon usage is optimized for E. coli and illegal restriction sites were removed. When you use this virG gene in a VirA/G signaling system you do not need <partinfo>BBa_K238010</partinfo> anymore to get the system working in E. coli.

vir-promoter, <partinfo>K389003</partinfo>: <partinfo>K389003 SpecifiedComponents</partinfo> new

Vir-promoters from A. tumefaciens are induced by phosphorylated VirG response regulators and control genes for infecting plants in their natural host. They are part of the VirA/G signal transduction system. This is a vir promoter from A. tumefaciens C58. It is located on the TI-plasmid upstream the virB genes.

firefly luciferase, <partinfo>K389004</partinfo>: <partinfo>K389004 SpecifiedComponents</partinfo> new

This is a BioBrick for a firefly (Photinus pyralis) luciferase. It is a sensitive reporter gene. It was isolated from Promega's pGL4.10luc2 plasmid.

Kanamycin resistance gene, <partinfo>K389005</partinfo>: <partinfo>K389005 SpecifiedComponents</partinfo> new
  • "our" kanamycin / neomycin resistance
  • used for directed evolution of virA and mutated virA screenings, respectively
  • isolated from the BioBrick <partinfo>P1003</partinfo>
virA generator, <partinfo>K389010</partinfo>: <partinfo>K389010 SpecifiedComponents</partinfo> composite
  • medium strong constitutive promoter, so there is enough VirA receptor expressed but not too much so the cell suffers from the expression
  • this version exists in a <partinfo>pSB1C3</partinfo> and a <partinfo>pSB1AT3</partinfo> vector
virA screening device, <partinfo>K389011</partinfo>: <partinfo>K389011 SpecifiedComponents</partinfo> composite
  • the new virG which works without rpoA is expressed constitutively and a kanamycin resistance gene is under the control of a vir promoter to screen mutants of virA (which are on a different plasmid in a <partinfo>K389010</partinfo>-like part)
  • the better the VirA receptor recognizes a substance the more resistant the cell is against kanamyin
  • this device has to be on a plasmid with different ori than the virA which should be screened (different compatibility classes)
  • we cloned this BioBrick into a plasmid with R6K ori which only works in pir+ or pir116 strains (e.g. E. coli EC100D), so we can easily seperate the two plasmids by transforming them into strains without Pir protein (e.g. E. coli TOP10)
virA reporter device with luc, <partinfo>K389012</partinfo>: <partinfo>K389012 SpecifiedComponents</partinfo> composite

  • this BioBrick is an assembly of <partinfo>K389010</partinfo> and <partinfo>K389012</partinfo>
  • used for characterizing the natural VirA/G system and the vir promoter, respectively
vir promoter characterisation part with mRFP, <partinfo>K389016</partinfo>: <partinfo>K389016 SpecifiedComponents</partinfo> composite
  • this BioBrick is an assembly of <partinfo>K389010</partinfo> and <partinfo>K389013</partinfo>
  • used for characterizing the natural VirA/G system and the vir promoter, respectively
vir promoter part, <partinfo>K389017</partinfo>: <partinfo>K389017 SpecifiedComponents</partinfo> composite
