The absence of YjbH leads to increased Sae activity and decreased Agr activity. Strains containing plasmids with the (a) Pcoa-lacZ or (b) Ppsmα-lacZ reporters for Sae and Agr activity, respectively. Samples were taken at mid-exponential phase of growth (6 h) and used in a β-galactosidase assay. Data are representative from ≥ 3 independent experiments. Bars represent the mean (n = 3 for (a) and n = 4 for (b)) with SEM. *, **, and *** indicate p < 0.05, p < 0.01, and p < 0.001 by t-test, respectively.
