Zusammenfassung

We report a salvage pathway in Gram-negative bacteria that bypasses de novo biosynthesis of UDP N-acetylmuramic acid (UDP-MurNAc), the first committed peptidoglycan precursor, and thus provides a rationale for intrinsic fosfomycin resistance. The anomeric sugar kinase AmgK and the MurNAc α-1-phosphate uridylyl transferase MurU, defining this new cell wall sugar-recycling route in Pseudomonas putida, were characterized and engineered into Escherichia coli, channeling external MurNAc directly to peptidoglycan biosynthesis.
