Abstract

Solution ¹⁷O-NMR application to biological macromolecules is extremely limited. We describe here ¹⁷O-NMR observation of the ¹⁷O₂-oxidized cysteine side chain of human Cu,Zn-superoxide dismutase in solution using selective ¹⁷O₂ oxidation. ¹⁷O-NMR with the aid of ¹⁷O-labeling has wide potential to probe the environment and dynamics of oxidizable functionalities in proteins.
