The RND family efflux pump FemT contributes to lipid homeostasis in Staphylococcus aureus”

The RND efflux pump FemT encoded by SAUSA300_2213 of Staphylococcus aureus USA300 is co-transcribed with femX which has an essential role in synthesizing the Lipid II precursor of peptidoglycan. Anticipating that this arrangement reflects a critical accessory role for femT, we constructed USA300ΔfemT to assess its func...

The oxidative stress regulator, PerR, is required for staphyloferrin B-mediated iron acquisition in Staphylococcus aureus

ABSTRACT Staphylococcus aureus is a globally prevalent gram-positive pathogen that can cause numerous types of infection. Due to host nutritional immunity and iron (Fe) sequestration, S. aureus experiences Fe limitation during infection. To overcome this, S. aureus expresses an arsenal of Fe acquisition systems whose e...
