Mutational analysis of the VirG protein, a transcriptional activator of Agrobacterium tumefaciens virulence genes.

Journal of bacteriology - 1 Oct 1990

Roitsch T, Wang H, Jin S G, Nester E W

Abstract excerpt

The VirG protein of Agrobacterium tumefaciens is required in conjunction with the VirA protein for transcriptional activation of the virulence (vir) genes in response to plant phenolic compounds. These proteins are members of a family of two component regulatory systems. vir genes are activated via a cascade of phosphorylation reactions involving a specific aspartic acid residue of the VirG protein. We have...
