REMARK 3 REMARK 3 REFINEMENT. REMARK 3 PROGRAM : AMBER 6.0 REMARK 3 AUTHORS : CASE, KOLLMAN ET AL. REMARK 3 REMARK 3 OTHER REFINEMENT REMARKS: 100 STRUCTURES WERE CALCULATED USING REMARK 3 DISTANCE GEOMETRY. THE 80 STRUCTURES OF LOWEST PENALTY REMARK 3 FUNCTION WERE REFINED USING THE SANDER MODULE OF AMBER (V6.0). REMARK 3 THE CALCULATION EMPLOYED 72 DISTANCE RESTRAINTS, 11 DIHEDRAL REMARK 3 ANGLE RESTRAINTS AND 8 CHEMICAL SHIFT RESTRAINTS. THE 20 REMARK 3 STRUCTURES OF LOWEST VIOLATION ENERGY WERE CHOSEN TO REPRESENT REMARK 3 THE STRUCTURE. THERE ARE NO VIOLATIONS OF THE INPUT RESTRAINTS REMARK 3 > 0.1 A OR 2 DEGREES. THE RMS. DIFFERENCE BETWEEN CALCULATION REMARK 3 AND OBSERVED CHEMICAL SHIFTS IS 0.07 PPM. 78% OF THE BACKBONE REMARK 3 GEOMETRIES ARE IN THE MOST FAVOURABLE REGION OFTHE REMARK 3 RAMACHANDRAN PLOT. THE BACKBONE HEAVY ATOM RMSD FROM THE MEAN REMARK 3 STRUCTURE IS 0.29+/-0.05 A.
