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 contains two <partinfo>B0010</partinfo> terminators
  • we used this because of problems mentioned in registry with <partinfo>B0012</partinfo>
RBS, <partinfo>B0034</partinfo>: <partinfo>B0034 SpecifiedComponents</partinfo> from registry
  • we always assembled a strong RBS
lacI gene, <partinfo>C0012</partinfo>: <partinfo>C0012 SpecifiedComponents</partinfo> from registry
  • used this to build the tightly regulated lac-operon <partinfo>K389050</partinfo>
mRFP, <partinfo>E1010</partinfo>: <partinfo>E1010 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
constitutive promoter, <partinfo>J23110</partinfo>: <partinfo>J23110 SpecifiedComponents</partinfo> from registry
  • we always used a medium strong constitutive promoter from the registry to express 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 only works in some E. coli strains, so it is used for a two plasmid screening system
virA, <partinfo>K238008</partinfo>: <partinfo>K238008 SpecifiedComponents</partinfo> from registry, fixed
  • we wanted to use the virA BioBrick from the registry but problems occurred, so we created our own virA from Agrobacterium tumefaciens C58 TI-plasmid
  • our own (working) virA is here: <partinfo>K389001</partinfo>
vir-promoter, <partinfo>K238011</partinfo>: <partinfo>K238011 SpecifiedComponents</partinfo> from registry, fixed
  • same as the virA BioBrick - this one from the registry does not work properly, so we made a vir-promoter by ourselves
  • 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
  • "our" virA
  • illegal PstI restriction site removed by site-directed mutagenesis
  • isolated from A. tumefaciens C58 TI-plasmid
virG, <partinfo>K389002</partinfo>: <partinfo>K389002 SpecifiedComponents</partinfo> synthesized, new
  • virG that works in E. coli without rpoA gene from A. tumefaciens
  • mutations ... + optimized codon-usage (E. coli) + removal of all illegal restriction sites because it was synthesized
vir-promoter, <partinfo>K389003</partinfo>: <partinfo>K389003 SpecifiedComponents</partinfo> new
  • "our" vir-promoter
  • is induced by phosphorylated VirG
  • isolated from A. tumefaciens C58 TI-plasmid
firefly luciferase, <partinfo>K389004</partinfo>: <partinfo>K389004 SpecifiedComponents</partinfo> new
  • "our" luciferase
  • sensitive reporter gene
  • 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 similar to <partinfo>K389011</partinfo> but with the reporter luciferase instead of an antibiotic resistance gene
  • with this BioBrick it is possible to measure the activity of the vir promoter and the VirA receptor, respectively
virA reporter device with mRFP, <partinfo>K389013</partinfo>: <partinfo>K389013 SpecifiedComponents</partinfo> composite
  • this BioBrick is similar to <partinfo>K389011</partinfo> but with the reporter mRFP instead of an antibiotic resistance gene
  • with this BioBrick it is possible to measure the activity of the vir promoter and the VirA receptor, respectively
Test, <partinfo>K389014</partinfo>: <partinfo>K389014 SpecifiedComponents</partinfo> composite
  • this BioBrick is an assembly of <partinfo>K389010</partinfo> and <partinfo>K389011</partinfo>
  • used for testing the general screening concept of expressing an antibiotic resistance with a vir promoter after induction with acetosyringone (the natural VirA inductor)
vir promoter characterisation part with luc, <partinfo>K389015</partinfo>: <partinfo>K389015 SpecifiedComponents</partinfo> composite
  • this BioBrick is an assembly of <partinfo>K389010</partinfo> and <partinfo>K389012</partinfo>
