Oxford video still introducing the molecular movie of penicillin formation▶ OXFORD MOLECULAR MOVIE
FEATURED DISCOVERY · 9 OCTOBER 2026

Watch penicillin take shape, one molecular snapshot at a time

Oxford researchers combined thousands of ultrafast X-ray snapshots to show how an enzyme builds penicillin’s signature ring. The movie reveals short-lived steps that scientists had not been able to observe directly.

Why it matters: Seeing how the enzyme guides this reaction may help researchers design improved antibiotics and new enzyme catalysts.
