| Details | THE STRUCTURE WAS DETERMINED USING PSEUDOCONTACT SHIFTS IN THE NMR SPECTRUM. PSEUDOCONTACT SHIFTS WERE MEASURED AS THE DIFFERENCE IN THE CHEMICAL SHIFT BETWEEN THE CO(II) COMPLEX AND THE ZN(II) COMPLEX. IN MODELS 1-3, ONLY SHIFTS WERE USED; IN MODELS 4-6 SHIFTS + NOE'S WERE USED IN REFINEMENT. |
