Graphical Abstract

Bigger is better: Sequential backbone assignments are obtained by NMR spectroscopy for a 1 MDa proteasome complex. The method relies on immobilization of a soluble protein complex by magic-angle spinning. Deuteration and proton detection of exchangeable sites and paramagnetic relaxation enhancement enables exploration of structural and dynamic properties of supramolecular assemblies at atomic resolution.
