One ring to fight them all: The sulfazecin story.
(2017) One ring to fight them all: The sulfazecin story. Cell Chem Biol 24(1), 1-2. (Review)
In this issue of Cell Chemical Biology, Li et al. (2017) report on the biosynthesis of the monobactam sulfazecin by Pseudomonas acidophila and hypothesize a novel mechanism of β-lactam ring formation. As monobactam antibiotics are unaffected by some emerging resistance mechanisms (particularly metallo-β-lactamases), this discovery opens prospects to engineer β-lactam antibiotics against multi-drug resistant pathogens.
