REMARK 3 PROGRAM : CNS 1.1 REMARK 3 AUTHORS : BRUNGER ET AL. REMARK 3 REMARK 3 OTHER REFINEMENT REMARKS: THE EXPERIMENTALLY DETERMINED REMARK 3 DISTANCE, DIHEDRAL AND DIPOLAR COUPLING RESTRAINTS WERE REMARK 3 APPLIED IN A SIMULATED ANNEALING PROTOCOL USING ARIA AND CNS. REMARK 3 NON-CRYSTALLOGRAPHIC SYMMETRY (NCS) RESTRAINTS WERE USED TO REMARK 3 ENFORCE THE DIMER SYMMETRY. THE FINAL ENSEMBLE OF NMR REMARK 3 STRUCTURES WAS REFINED IN A SHELL OF WATER MOLECULES.
