Paramagnetic metalloproteins are proteins containing one or more paramagnetic metal ions, which are characterized by the presence of at least one unpaired electron. As in every molecule, unpaired electrons sizably perturb the NMR parameters relative to the protein nuclei, changing their relaxation, chemical shift, and motional averaging so that paramagnetic enhancements in relaxation rates, hyperfine shifts, and residual dipolar couplings arise.

Abstract
Paramagnetic metalloproteins are proteins containing one or more paramagnetic metal ions, which are characterized by the presence of at least one unpaired electron. As in every molecule, unpaired electrons sizably perturb the NMR parameters relative to the protein nuclei, changing their relaxation, chemical shift, and motional averaging so that paramagnetic enhancements in relaxation rates, hyperfine shifts, and residual dipolar couplings arise.
