REMARK 3 PROGRAM : X-PLOR REMARK 3 AUTHORS : BRUNGER REMARK 3 REMARK 3 OTHER REFINEMENT REMARKS: RESTRAINED MOLECULAR DYNAMICS REMARK 3 CALCULATIONS WERE DONE ON IDEALIZED A'- AND B-FORM STARTING REMARK 3 STRUCTURES. ONLY THE TRIPLEX REGION AND THE FIRST AND LAST REMARK 3 RESIDUES OF EACH OF THE TWO LOOPS IN THE SEQUENCE WERE REMARK 3 CONSIDERED. THE REFINEMENT WAS CONDUCTED IN TWO STAGES. IN THE REMARK 3 FIRST STAGE, SIX STRUCTURES WERE CALCULATED (THREE FROM EACH REMARK 3 STARTING STRUCTURE) USING DISTANCE RESTRAINTS. IN THE SECOND REMARK 3 STAGE, TWO OF THE SIX STRUCTURES WERE REFINED DIRECTLY AGAINST REMARK 3 PRIMARY NOE DATA. THE R(1/6) VALUE WAS USED TO MONITOR THE REMARK 3 REFINEMENT DURING THIS STAGE. THE FINAL R(1/6) VALUES FOR THE REMARK 3 TWO AVERAGED MINIMIZED STRUCTURES WERE 0.04 AND 0.045. THE REMARK 3 SUMMATION RUNS THROUGH ALL OBSERVED, QUANTIFIABLE CROSSPEAK REMARK 3 INTENSITIES IN NOESY SPECTRA RECORDED AT MIXING TIMES OF 40, 90 REMARK 3 AND 150 MS.
