PheP, a Putative Amino Acid Permease of <i>Staphylococcus aureus</i> , Contributes to Survival In Vivo and during Starvation

Abstract

PheP, a putative amino acid permease in Staphylococcus aureus, contributes to starvation survival under glucose-limiting conditions and virulence. A pheP mutation led to poor growth after microaerobic or anaerobic incubation on pig serum agar, which was recovered by phenylalanine addition. Genetic complementation of pheP restored growth and starvation survival.
