Opposing Effects of PhoPQ and PmrAB on the Properties of <i>Salmonella enterica</i> serovar Typhimurium: Implications on Resistance to Antimicrobial Peptides.

Further support for the differences in membrane permeability comes from the SYTOX experiments in which we measure the extent of membrane permeability. The data showed a trend that is similar to that of the membrane polarizing experiment, i.e. , the WT and pmrAB-KO are less permeable than phoP-KO and the DKO ( Figure 2 ).
