Mutants of Agrobacterium tumefaciens virG gene that activate transcription of vir promoter in Escherichia coli.

Current microbiology - 1 Nov 2004

Jung Yong-Chul, Gu Yunrong, Wu Donghai, Jin Shouguang

Abstract excerpt

The virA and virG two-component regulatory system is essential for transcriptional activation of virulence (vir) genes in Agrobacterium tumefaciens in the presence of inducer molecules. The VirA/VirG mediated vir gene transcription depends on a specific interaction between the C-terminal domain of the alpha subunit (RpoA) of A. tumefaciens RNA polymerase (RNAP) and N-terminal domain of the VirG. However, such...
