REMARK 3 REMARK 3 REFINEMENT. REMARK 3 PROGRAM : X-PLOR 3.1 REMARK 3 AUTHORS : BRUNGER REMARK 3 REMARK 3 OTHER REFINEMENT REMARKS: CHARM22 A TOTAL OF 50 INITIAL REMARK 3 STRUCTURES WERE CALCULATED USING A SIMULATED ANNEALING PROGRAM REMARK 3 AS 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.
