| distance geometry | 1000 STRUCTURES WERE INITIALLY GENERATED USING THE DISTANCE GEOMETRY PROGRAM DYANA 1.4. THESE STRUCTURES WERE REFINED USING SIMULATED ANNEALING IN X-PLOR3.8 WITH THE DISTANCE GEOMETRY FORCE FIELD, THEN ENERGY MINIMIZED USING THE CHARMM FORCE FIELD WITH A DISTANCE-DEPENDENT DILECTRIC. THE 20 BEST STRUCTURES BASED ON THEIR STEREOCHEMICAL AND NOE ENERGIES WERE CHOSEN FOR ANALYSIS. | X-PLOR |
