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.
