Résumé

Antibiotic resistant Staphylococcus aureus is becoming a major burden on healthcare systems in many countries, necessitating the identification of new targets for antibiotic development. Elongation Factor P (EF-P) is a highly conserved elongation protein factor that plays an important role in protein synthesis and bacteria virulence. EF-P undergoes unique posttranslational modifications in a stepwise manner in order to function correctly, but experimental information on EF-P posttranslational modifications is currently lacking for S. aureus. Here, we expressed EF-P in S. aureus to analyze its posttranslational modifications by mass spectrometry, and report experimental proof of 5-aminopentanol modification of S. aureus EF-P.
