(13)C[(13)C] 2D NMR: a novel strategy for the study of paramagnetic proteins with slow electronic relaxation rates.

Timothy E Machonkin1, William M Westler, John L Markley.   

Abstract

Oxidized human [2Fe-2S] ferredoxin has a notably slow electronic relaxation rate, which precludes the observation of signals from nuclei near the iron-sulfur cluster by conventional 2D or 3D methods that utilize proton detection. We have demonstrated the utility of (13)C[(13)C]CT-COSY in identifying connectivity information from fast relaxing carbon nuclei near the paramagnetic center, including those from residues that ligate the metal center.
