To investigate the contribution of the ClpXP protease to the virulence of serovar Typhimurium we initially cloned the clpX operon from the pathogenic strain serovar Typhimurium x3306
Levels of FlhC , in the ClpXP protease-depleted mutant Our previous study showed that the level of bgalactosidase activity in cells was not changed , in contrast to the marked increase of bgalactosidase levels , by mutations in either clpX .
Levels of FlhD , in the ClpXP protease-depleted mutant Our previous study showed that the level of bgalactosidase activity in cells was not changed , in contrast to the marked increase of bgalactosidase levels , by mutations in either clpX .
Levels of master regulators , in the ClpXP protease-depleted mutant Our previous study showed that the level of bgalactosidase activity in cells was not changed , in contrast to the marked increase of bgalactosidase levels , by mutations in either clpX .
