VirA/G signaling system without read-out
''A. tumefaciens'' C58 TI-plasmid, partsregistry, Mr. Gene
This BioBrick is a virA/G signaling system without read-out. It contains an unmutated ''virA'' gene and a ''virG'' gene that works without ''rpoA'' from ''A. tumefaciens'' and a ''vir'' promoter.
This BioBrick can be used to control any gene with a ''vir'' promoter
Double terminator with two copies of <bb_part>BBa_B0010</bb_part>
This is the ''virG'' response regulator from the virA/G receptor system. The virA/G receptor system is used by ''Agrobacterium tumefaciens'' to detect phenolic substances secreted by plants. In presence of these substances, ''virG'' is activated by the ''virA'' receptor and induces the transcription of genes under the control of a ''vir'' promotor. Normally, ''virG'' needs the ''rpoA'' RNA polymerase subunit from ''A. tumefaciens'' to work in ''Escherichia coli'' but this ''virG'' BioBrick is mutated, so works with the ''rpoA'' subunit from ''E. coli''.
synthesized by Mr. Gene, so optimated codon usage, removal of illegal restriction sites
This is a ''vir'' promotor from ''Agrobacterium tumefaciens'' C58. It is located on the TI-plasmid before the ''virB'' genes. It is activated by phosphorylated ''virG'' response regulator.
This BioBrick contains a ''virA'' receptor from ''Agrobacterium tumefaciens'' C58 under the control of a constitutive promotor. We used it to mutate ''virA'' by error-prone PCR. For screening the mutants BBa_K389011 is also needed.
The ''virA'' gene is under the control a medium strong constitutive promotor.
RBS (Elowitz 1999) -- defines RBS efficiency
Varies from -6 to +1 region from original sequence to accomodate BioBricks suffix. 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.

''Agrobacterium tumefaciens'' C58, TI-plasmid
This is a gene for the ''virA'' receptor from ''Agrobacterium tumefaciens'' C58. An illegal ''PstI'' restriction site was removed by site-directed mutagenesis.
