Low concentration and poor sensitivity often hinder or make impossible solid-state 17O NMR in large biomolecular systems. In this cover article in Angewandte Chemie Gang Wu (Queen’s) and co-workers from the University of Ottawa and NRC Canada show that at an ultrahigh magnetic field of 21 T the high quality solid-state 17O NMR spectra can be obtained for large protein–ligand complexes of up to 300 kDa in size. Complementary multinuclear 17O, 27Al, and 13C NMR data obtained in this work have aided in the structural refinement for an ovotransferrin bound Al-oxalate complex.

This is an ninth cover article featuring results obtained using resources of the National Ultrahigh-Field NMR Facility for Solids. See our cover gallery and the complete list of research publications enabled by the Facility here (complete list).
