| HYBRID DISTANCE GEOMETRY AND SIMULATED ANNEALING | THE STRUCTURES OF THE MONOMERS WERE CALCULATED USING MATRIX DISTANCE GEOMETRY, FOLLOWED BY SIMULATED ANNEALING. THE MONOMERS WERE THEN DUPLICATED AND EACH NEW SUBUNIT WAS ROTATED 180 DEGREES AND SEPARATELY FROM ITS PARTNER BY 40 ANGSTROMS. NO DOCKING OF THE TWO MONOMERS WAS ATTEMPTED PRIOR THE FURTHER STRUCTURE CALCULATIONS. DIMER STRUCTURE CALCULATIONS USED THE 40 UNAMBIGUOUS INTERMONOMER NOES TO BRING THE SUBUNITS IN A POSITION RELATIVE TO ONE ANOTHER. A FURTHER FOUR ROUNDS OF SIMULATED ANNEALING GENERATED THE FINAL STRUCTURES. AT NO POINT DURING THE DIMER CALCULATIONS WAS NON-CRYSTALLOGRAPHIC SYMMETRY UTILIZED. | X-PLOR |
