Effect of NaCl and divalent cations on the antimicrobial activity of HydH5. A) Activity was determined in 50 mM phosphate buffer containing different NaCl ionic strength. B) Activity was determined in the presence of different concentrations of CaCl2, MgCl2, and MnCl2( 0 mM, 0.75 mM, 1.25 mM, 10.25 mM). Error bars are the means ± standard deviations of three independent assays.
