Measurement of ATP leakage from Staphylococcus aureus after treatment with plectasin (A), eurocin (B), protamine (C), and novicidin (D). Measurement of intracellular (IC) and extracellular (EC) ATP after treatment with plectasin (500 μg/ml), eurocin (500 μg/ml), protamine (1,000 μg/ml), novicidin (1,000 μg/ml), or peptide dilution buffer. Treatment with the two defensins does not lead to leakage of intracellular ATP, whereas treatment with protamine and novicidin lead to leakage of ATP. Representative results from S. aureus are shown as treatment of S. aureus and L. monocytogenes resulted in similar leakage profiles. The experiment shown is representative of two independent experiments.
