REMARK 3 PROGRAM : X-PLOR NIH REMARK 3 AUTHORS : SCHWIETERS, C.D. ET AL. REMARK 3 REMARK 3 OTHER REFINEMENT REMARKS: STRUCTURES WERE CALCULATED USING THE REMARK 3 PROGRAM XPLOR-NIH (SCHWIETERS ET AL., 2002). THE SECONDARY REMARK 3 STRUCTURE OF THE MONOMER WAS FIRST CALCULATED FROM RANDOM COIL REMARK 3 USING INTRA-SUBUNIT NOES, BACKBONE DIHEDRAL RESTRAINTS DERIVED REMARK 3 FROM CHEMICAL SHIFTS (TALOS) (CORNILESCU ET AL., 1999), AND SIDE REMARK 3 CHAIN χ1 RESTRAINTS. A TOTAL OF 20 MONOMER STRUCTURES WERE REMARK 3 CALCULATED USING A STANDARD HIGH-TEMPERATURE SIMULATED ANNEALING REMARK 3 (SA) PROTOCOL IN WHICH THE BATH TEMPERATURE WAS COOLED FROM 1000 REMARK 3 TO 200 K. TO OBTAIN AN INITIAL SET OF TETRAMER STRUCTURES, FOUR REMARK 3 COPIES OF THE LOWEST-ENERGY MONOMER STRUCTURE CALCULATED ABOVE REMARK 3 WERE USED. THE SAME SA RUN WAS PERFORMED IN THE PRESENCE OF REMARK 3 INTER-SUBUNIT NOES AND ALL OTHER INTRA-SUBUNIT RESTRAINTS. FOR REMARK 3 EACH EXPERIMENTAL INTER-SUBUNIT NOE BETWEEN TWO ADJACENT REMARK 3 SUBUNITS, FOUR IDENTICAL DISTANCE RESTRAINTS WERE ASSIGNED REMARK 3 RESPECTIVELY TO ALL PAIRS OF NEIGHBORING SUBUNITS TO SATISFY THE REMARK 3 CONDITION OF C4 ROTATIONAL SYMMETRY. DURING THE ANNEALING RUN, REMARK 3 THE BATH WAS COOLED FROM 1000 TO 200 K WITH A TEMPERATURE STEP REMARK 3 OF 20 K. A TOTAL OF 100 TETRAMER STRUCTURES WERE CALCULATED. FOR REMARK 3 BM2(1-33), 15 LOW ENERGY STRUCTURES WERE SELECTED AS THE REMARK 3 STRUCTURAL ENSEMBLE.
