Fur delays onset of hlyII expression. Cells were grown in LB at 28°C. Corresponding growth curves are shown in each panel (thin lines). Each experiment was performed at least three times. Results from representative experiments are shown. (A) Effects of iron and DPD on HlyII production in B. subtilis EH2. The average ratio of hemolytic activities between curves is shown in the inset. (B) Effects of iron and DPD on HlyII production in B. subtilis EH2R.
