---|---|
Details | The structure of the protein was determined using multidimensional NMR spectroscopy. The structure of EMD 57033 in the complex was determined using 15N/13C-filtered-NOESY and DIPSI experiments. The contacts between protein and EMD 57033 were determined using 15N/13C-filtered/edited experiments. |
