Abstract excerpt
Agrobacterium tumefaciens virulence genes are induced by plant signals through the VirA-VirG two-component regulatory system. The VirA protein is a membrane-spanning sensor molecule that possesses an autophosphorylating activity, and the VirG protein is a sequence-specific DNA-binding protein. In this report, we demonstrate that the VirG protein is phosphorylated by the VirA protein and that the phosphate is...
