REMARK 3 REMARK 3 REFINEMENT. REMARK 3 PROGRAM : X-PLOR 3.1 REMARK 3 AUTHORS : BRUNGER REMARK 3 REMARK 3 OTHER REFINEMENT REMARKS: A TOTAL OF 50 INITIAL STRUCTURES REMARK 3 WERE CALCULATED USING A SIMULATED ANNEALING PROGRAM AS REMARK 3 SUPPLIED WITH X-PLOR 3.1. THE FINAL 20 STRUCTURES WITH THE REMARK 3 LOWEST OVERALL ENERGIES AND FEWEST VIOLATIONS OF NOE AND REMARK 3 DIHEDRAL RESTRAINTS WERE ENERGY MINIMIZED IN X-PLOR USING THE REMARK 3 CHARMM FORCEFIELD [BROOKS ET AL. (1983) J. COMPUT. CHEM., VOL. REMARK 3 4 187-217.]
