Beyond frozen snapshots, protein 'breathing' comes into view with combined imaging methods

Advances in structural biology have allowed scientists to determine molecular structures with atomic-level detail, sometimes yielding static snapshots that do not reflect the dynamism of proteins.

However, these motions are often crucial for biological function.

Researchers from the Institute of Science and Technology Austria (ISTA), together with international collaborators, have now combined several methods to shed light on how proteins "breathe" and how some experimental techniques freeze their motion.

The findings—which could boost protein design approaches and improve AI-based structural prediction tools—are published in Nature Chemistry. ...
