FIG 1.

Transformation efficiency of C. jejuni CtsE and CtsP mutants. Strains are complemented with pECO102, pECO102 expressing the wild-type coding sequence with a C-terminal FLAG tag, or pECO102 expressing the coding sequence with a Walker box mutation and a C-terminal FLAG tag. The data represent averages of the results from three samples per strain from one experiment. Experiments were repeated at least three times with similar results. Error bars indicate standard deviations. The limit of detection is indicated with a dashed line. Stars indicate P values calculated using one-way analysis of variance (ANOVA) with Dunnett's multiple-comparison test.
