Expression from PgbpC-gusA in the sensor kinase mutants. Fourteen different sensor kinases were inactivated in IBS131 in order to measure their effect on PgbpC-gusA expression. Strains were grown in THY broth at 37°C and harvested at the mid-exponential phase, and gusA activity was measured. The values were normalized with Gus activity obtained with IBS131. Experiments were repeated at least twice, and the mean values are shown.
