REMARK 3 REMARK 3 REFINEMENT. REMARK 3 PROGRAM : DISCOVER 3.1 REMARK 3 AUTHORS : ACCELRYS REMARK 3 REMARK 3 OTHER REFINEMENT REMARKS: THE STRUCTURES ARE BASED ON 70 NOE REMARK 3 DISTANCE RESTRAINTS, 8 PHI AND 3 CHI-1 DIHEDRAL ANGLE REMARK 3 RESTRAINTS. NO HYDROGEN BOND RESTRAINTS WERE EMPLOYED. NOTE REMARK 3 THAT THE HA-HB COUPLING CONSTANTS INDICATE ROTATIONAL REMARK 3 AVERAGING ABOUT THE PHE4 CHI-1 ANGLE. SEVERAL NOES TO THE REMARK 3 AROMATIC RING OF PHE4 WERE NOT USED TO GENERATE RESTRAINTS AS REMARK 3 THEY COULD BE SATISFIED BY A -60 OR 180 DEGREE ROTAMER, BUT REMARK 3 NOT BY BOTH. THE MEAN BACKBONE ATOM RMSD TO THE MEAN STRUCTURE REMARK 3 WITHIN THE DISULFIDE CYCLE IS 0.31 +/- 0.06 ANGSTOMS.
