Engineering a production platform for the potent antipseudomonal antibiotic mureidomycin A by reprogramming the pacidamycin biosynthetic gene cluster
Uridyl peptide antibiotics display potent activity against Pseudomonas aeruginosa, a pathogen causing severe nosocomial infections. The four subclasses—mureidomycins, pacidamycins, napsamycins, and sansanmycins—inhibit the underexplored bacterial target phospho-MurNAc-pentapeptide translocase (MraY). Structurally, thes...
