Additional NMR Experimental Information
Details	THIS STRUCTURE REPRESENTS THE A CONFORMATION OF THE RAT FERROCYTOCHROME B5. IT IS THE STRUCTURE CLOSEST TO THE AVERAGE AS ANALYZED BY X-PLOR. 200 STRUCTURES WERE CALCULATED USING DIANA 2.1 AND ONE STRUCTURE WAS CHOSEN TO REPRESENT THE FINAL RESULTS. THE STRUCTURE WAS DETERMINED USING 2D AND 3D EXPERIMENTS INCLUDING DISTANCE AND ANGULAR RESTRAINTS FROM HNHA.
