REMARK 3 PROGRAM : X-PLOR 3.8 REMARK 3 AUTHORS : BRUNGER REMARK 3 REMARK 3 OTHER REFINEMENT REMARKS: A TOTAL OF 100 INITIAL STRUCTURES OF REMARK 3 THE COMPLEX WERE GENERATED USING THE X-PLOR METRIC MATRIX REMARK 3 DISTANCE GEOMETRY PROTOCOL GUIDED BY THE NOE DISTANCE REMARK 3 RESTRAINTS. ALL THE DISTANCE WERE SUBJECTED TO TWO ROUNDS OF REMARK 3 MOLECULAR DYNAMICS REFINEMENT WITH THE NONBO NDED INTERACTIONS REMARK 3 SUBJECTED TO A REPULSIVE FORCE FIELD IN THE INITIAL ROUND AND A REMARK 3 CHARMM-22 FORCE FIELD CONTAINING VAN DER WAALS AND HYDROGEN BOND REMARK 3 (WITH WELL DEPTH OF 3 KCAL/MOL) ENERGY TERM IN THE SUBSEQUENT REMARK 3 ROUND. THE ELECTROSTATIC ENERGY TERM WAS TURNE D OFF DURING BOTH REMARK 3 ROUNDS OF THE COMPUTATIONS. THE MOLECULAR DYNAMICS PROTOCOL REMARK 3 DURING EACH ROUND OF THE COMPUTATIONS WAS AS FOLLOWS. THE REMARK 3 STRUCTURES WERE HEATED TO 1000K AND EQUILIBRATED AT THIS REMARK 3 TEMPERATURE FOR 0.8 PS, FOLLOWED BY GRADUAL COOLING TO 300 K O REMARK 3 VER 48 PS AND SUBSEQUENT EQUILIBRATION AT THIS TEMPERATURE FOR 6 REMARK 3 PS. THE RESULTING STRUCTURES WERE SUBJECTED TO 2,000 CYCLES OF REMARK 3 ENERGY MINIMIZATION. THE FORCE CONSTANTS FOR NOE DISTANCE REMARK 3 RESTRAINTS AND COUPLING CONSTANT BASED DIHEDRAL ANGLE RESTRAINTS REMARK 3 WERE MAINTAINED AT VALUES 50 KCAL/MOL A A AND 25 KCAL/MOL RAD REMARK 3 RAD, RESPECTIVELY THROUGHOUT THE CALCULATIONS. A FORCE CONSTANT REMARK 3 OF 60 KCAL/MOL A A WAS APPLIED TO MAINTAIN HYDROGEN BONDING REMARK 3 DISTANCE RESTRAINTS FOR WATSON-CRICK BASE PAIRS IN THE RNA STEM REMARK 3 OF THE CO MPLEX. A SUBSET OF 27 REFINED STRUCTURES WERE SELECTED REMARK 3 BASED ON THEIR LOWER VALUES OF TOTAL ENERGY, VAN DER WAALS REMARK 3 ENERGY AND NOE VIOLATIONS ENERGY. THESE 27 REFINED STRUCTURES REMARK 3 DEFINED A NOTICEABLE CONVERGED SUBSET (~10 KCAL/MOL VARIATION OF REMARK 3 TOTAL ENERGY W ITHIN SUBSET) AND WERE SEPARATED BY A GAP OF ~120 REMARK 3 KCAL/MOL OF TOTAL ENERGY FROM THE REST OF THE ENSEMBLE OF REMARK 3 REFINED STRUCTURES. THE 20 STRUCTURES OF THE COMPLEX WITH THE REMARK 3 LOWEST NUMBER OF NOE VIOLATIONS EXHIBITED PAIRWISE R.M.S.D. REMARK 3 VALUE FOR ALL HEAVY ATOMS OF 1.27 A.
