Scientists at the University of Oxford, with international collaborators, have captured a 'molecular movie' showing the rapid chemical steps in how penicillin and other β-lactam antibiotics are produced. Published in Nature Catalysis, the study reveals previously unseen stages in the formation of these vital drugs. The research focuses on the enzyme isopenicillin N synthase (IPNS), which performs a key ring-forming reaction. By using advanced time-resolved crystallography, the team observed fleeting intermediate states that last mere milliseconds.
This level of detail was previously impossible, offering the clearest view yet of the antibiotic assembly line. Understanding these fast chemical transformations matters because penicillin and its relatives are still widely used, yet bacterial resistance is growing. Knowing exactly how nature builds the β-lactam ring could help scientists design new antibiotics or engineer enzymes to make modified versions.
