Membrane homeostasis requires intact pst in extraintestinal pathogenic Escherichia coli.

Abstract excerpt

In extraintestinal pathogenic Escherichia coli (ExPEC) strains, mutation in the PstSCAB inorganic phosphate transporter results in multiple sensitivity phenotypes and loss of virulence. Here, we show that a pst mutant is subject to an increased outer membrane permeability and that pst copy number influences fatty acids regulation. Such perturbations are likely to participate in the impaired response of pst...
