REMARK 3 PROGRAM : VNMR 6.1B, FELIX 970, X-PLOR 3.1 REMARK 3 AUTHORS : VARIAN (VNMR), MSI (FELIX), BRUNGER (X-PLOR) REMARK 3 REMARK 3 OTHER REFINEMENT REMARKS: 303 NOE VOLUME CONSTRAINTS FROM THE 100 REMARK 3 MS AND 498 NOE FROM THE 250 MS NOESY DATA WERE USED. IN ADDITION REMARK 3 10 NOE CONSTRAINTS INVOLVING THE IMINO PROTONS OF RESIDUES G1, REMARK 3 G5, G6, G8, G10, G14, AND G15 WERE USED AS DISTANCE CONSTRAINTS. REMARK 3 FOUR HYDROGEN BONDS WERE USED FOR EACH GUANINE INVOLVED IN A REMARK 3 QUARTET. EXPERIMENTAL COUPLING CONSTANTS WERE USED TO GENERATE REMARK 3 45 DIHEDRAL CONSTRAINTS, 15 FROM BASHD-TOCSY EXPERIMENTS (H3*- REMARK 3 31P), AND 30 FROM PE-COSY DATA (H1*-C1*- C2*-1H2* AND H1*-C1*-C2* REMARK 3 -2H2*). ADDITIONAL CONSTRAINTS WERE USED TO KEEP THE PURINE REMARK 3 RINGS PLANAR. THE STARTING STRUCTURE USED WAS THE STRUCTURE REMARK 3 OBTAINED IN A PREVIOUS REFINEMENT. THE NON-BONDED INTERACTION REMARK 3 CUT-OFF WAS SET TO 11.5 A, USING X-PLOR PROTOCOLS. THE ACTIVE REMARK 3 DISTANCE OF THE SWITCHING FUNCTIONS WAS 7.5 TO 10.5 A. THE REMARK 3 DISTANCE CUT-OFF FOR THE HYDROGEN BONDING INTERACTIONS WAS 7.5 REMARK 3 A. THE SWITCHING FUNCTION FOR HYDROGEN BONDING INTERACTIONS WAS REMARK 3 ACTIVE FROM 4.0 TO 6.5 A. THE ENERGY OF THE STARTING STRUCTURE REMARK 3 WAS MINIMIZED IN 200 STEPS OF POWELL'S CONJUGATE GRADIENT REMARK 3 MINIMIZATION. THE RELAXATION MATRIX REFINEMENTS WERE CARRIED OUT REMARK 3 IN VACUUM AT 300K WITH A RELATIVE WEIGHTING OF ALL THE REMARK 3 EXPERIMENTAL CONSTRAINTS (NOE, DISTANCE AND DIHEDRAL) OF 60 KCAL/ REMARK 3 MOL. SUBSEQUENTLY, A 100 PS RELAXATION MATRIX TRAJECTORY WAS REMARK 3 CONDUCTED WITH STRUCTURES SAVED EVERY 2 PS. THE TRAJECTORIES REMARK 3 STABILIZED AFTER 30 PS. UPON COMPLETION OF THE SIMULATION AN REMARK 3 ADDITIONAL 200 STEP CONJUGATE GRADIENT MINIMIZATION WAS REMARK 3 CONDUCTED TO PRODUCE THE FINAL STRUCTURES. THE ROOT MEAN SQUARE REMARK 3 DEVIATION {OF WHAT?} WAS CALCULATED TO BE 0.14. THE NOE CROSS- REMARK 3 PEAK VOLUMES OF THE STRUCTURES OBTAINED BETWEEN 80-100 PS AT REMARK 3 INTERVALS OF 2 PS WERE BACKCALCULATED USING THE FELIX 970 REMARK 3 SOFTWARE PACKAGE (MSI INC.) PARAMETERS USED IN THE REMARK 3 BACKCALCULATION PROTOCOL ARE AS FOLLOWS: A CORRELATION TIME OF REMARK 3 5.0 NS, A Z-LEAKAGE RATE OF 3.0 S-1 AND A DISTANCE CUT OFF OF REMARK 3 7.5 A. NOE SPECTRA OF THESE 10 STRUCTURES WERE THEN REMARK 3 BACKCALCULATED AND AVERAGED. 40 NOE INTENSITIES FROM THE REMARK 3 EXPERIMENTAL NOESY SPECTRA WERE USED TO NORMALIZE THE REMARK 3 BACKCALCULATED TO THE THEORETICAL NOES. THE NORMALIZATION AND REMARK 3 AVERAGING PROCESSES WERE CONDUCTED ON A IN HOUSE PROGRAM. THE REMARK 3 RMS, R AND Q VALUES OF THE AVERAGED STRUCTURE THAT ARE 0.28, REMARK 3 0.68 AND 0.30.
