FIG. 2.
The pmrHFIJKLM genes are expressed as an operon. PmrA−, PmrAc, and PmrAc pmrF::Tn10d strains were examined. Each strain contained a single-copy pmrM::luc fusion and was assayed in logarithmic phase (OD600, 0.6) for firefly luciferase-activity (expressed as relative light units [RLU]). The data are from a single experiment of three independent assays that gave similar results.
