Short summary
Protein structure and motion are key to its function. Using electron paramagnetic resonance (EPR) methods, it is possible to measure distances between magnetic markers like gadolinium ions grafted on proteins. Such measurements rely on the gadolinium phase memory time, determining how long the signal lasts. We studied how nearby atoms and environmental noise affect signal lifetimes using advanced EPR techniques. Our findings show how lifetimes can be extended to design better protein analysis.
