VirA receptor

The VirA receptor of Agrobacterium tumefaciens

The VirA receptor is used by Agrobacterium 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.


Usage and Biology

For a working VirA/G-receptor system, you also need the virG BioBrick BBa_K389002 and a vir promoter BBa_K389003. You can find an already assembled VirA/G-receptor system here: BBa_K389017.

This receptor recognizes acetosyringone.
