REMARK 3 PROGRAM : DISCOVER 3.0 REMARK 3 AUTHORS : ACCELRYS REMARK 3 REMARK 3 OTHER REFINEMENT REMARKS: 100 DISTANCE GEOMETRY STRUCTURES REMARK 3 WERE CALCULATED. THE 80 STRUCTURES OF LOWEST PENALTY FUNCTION REMARK 3 WERE FURTHER REFINED USING RESTRAINED MOLECULAR DYNAMICS. THE REMARK 3 20 STRUCTURES OF LOWEST RESTRAINT VIOLATION ENERGY WERE USED REMARK 3 TO DESCRIBE THE STRUCTURE. 61 DISTANCE AND 21 DIHEDRAL ANGLE REMARK 3 RESTRAINTS WERE USED. THE FINAL ENSEMBLE HAS NO DISTANCE REMARK 3 VIOLATIONS GREATER THAN 0.1 A AND NO DIHEDRAL ANGLE VIOALTIONS REMARK 3 GREATER THAN 1 DEGREE. 95% OF THE RESIDUES ARE IN THE MOST REMARK 3 FAVOURABLE REGION OF THE RAMACHANDRAN PLOT. THE MEAN BACKBONE REMARK 3 ATOM RMSD TO THE MEAN STRUCTURE IS 0.29+/-0.05 A.
