Figure 2.

Effect of overexpression of sigma factors on the PmucEexpression. The sigma factors AlgU, RpoD, RpoN, RpoS and RpoF were expressed from an arabinose-inducible promoter in pHERD20T [16], and the PmucE activity was determined via β-galactosidase assay from a merodiploid strain of PAO1 carrying PmucE-lacZ integrated on the chromosome. The values reported in this figure represent an average of three independent experiments with standard error.
