REMARK 3 REMARK 3 REFINEMENT. REMARK 3 PROGRAM : DGII V98.0, DISCOVER V98.0, TALOS FEB 2000 REMARK 3 AUTHORS : HAVEL (DGII), ACCELRYS (DISCOVER), DELAGLIO & REMARK 3 BAX (TALOS) REMARK 3 REMARK 3 OTHER REFINEMENT REMARKS: THE STRUCTURES ARE BASED ON 91 REMARK 3 DISTANCE RESTRAINTS AND 26 DIHEDRAL ANGLE RESTRAINTS. NONE OF REMARK 3 THE FINAL STRUCTURES HAVE VIOLATIONS > 0.07A OR 1.0 DEGREES. REMARK 3 THE MEAN RMSD TO THE MEAN COORDINATES FOR HEAVY ATOMS OF REMARK 3 RESIDUES CYS3 TO TYR15 IS 0.31+/-0.06 A.
