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 300 STRUCTURES WERE REMARK 3 CALCULATED USING DISTANCE GEOMETRY UTILIZING 123 REMARK 3 EXPERIMENTALLY DERIVED DISTANCE RESTRAINTS FOR THE LOOP AND REMARK 3 918 (258-EXPERIMENTAL DISTANCES, 660-A FORM DISTANCES) REMARK 3 DISTANCE RESTRAINTS FOR THE STEM REGION AND 143 DIHEDRAL ANGLE REMARK 3 RESTRAINTS. ADDITIONALLY, 50 DISTANCE RESTRAINTS WERE USED TO REMARK 3 MAINTAIN THE WATSON-CRICK GEOMETRY OF THE BASE PAIRS IN THE REMARK 3 STEM REGION. FINAL REFINEMENT RESULTED IN 10 LOWEST ENERGY REMARK 3 STRUCTURES.
