ChvG

Acidic condition plays an important role in Agrobacterium-plant interactions (1).

Numerous studies have investigated the possible connection between the physiological response to acidic conditions and the activity of ChvG and ChvI. Studies have shown that ChvG /ChvI two component systems specifically get induced in an acidic environment (1).

As a result, there is growing consensus that the ChvG/ChvI, two-component regulatory system, may be the primary global pH sensor in Agrobacterium tumefaciens and as such, serves in coordinating the expression of acid-induced genes (2).

ChvI

ChvI is the response regulator of the ChvG/ChvI two component regulatory system found in Agrobacterium (4).

ChvG ---> ChvI

ChvG and ChvI is the sensor kinase, and cognate response regulator, respectively, of two component regulatory system in Agrobacterium thought to respond to extracellular pH changes (2).

PhoB

PhoB is a response regulator in E.coli that gets activated by a histidine kinase and phosphate sensor called PhoR (6).

PhoR

PhoR is a histidine kinase and a phosphate sensor in E.coli that activates a response regulator called PhoB (6).
