Function

Compared with the parental strain, expression of PcomG-gfp was increased approximately 2.5-fold in the Δ12 strain, significantly lowered (approximately 4-fold) in the Δ13 TCS mutant, and, in strain Δ17, expression was completely abolished, indicating that TCS17 is essential for comG expression under these conditions.
