TAD	A TOTAL OF 2292 NOE INTERPROTON DISTANCE RESTRAINTS, 83 PAIRS OF PSI AND PHI AND BACKBONE DIHEDRAL ANGLE RESTRAINTS, AND 146 PAIRS OF H-BOND RESTRAINTS WERE USED TO CALCULATE AN ENSEMBLE OF STRUCTURES USING A MODIFIED VERSION OF THE ORIGINAL TORSION ANGLE DYNAMICS PROTOCOL ROUTINE WITHIN CNS. THE TAD PROTOCOL WAS AS FOLLOWS. 75 PS HIGH-TEMPERATURE TAD 50000 K FOLLOWED BY COOLING TO 1000 K OVER THE COURSE OF 75 PS AND RAMPING OF THE VAN DER WAALS SCALING TERM FROM 0.1 TO 1.0. THE MOLECULES WERE FURTHER COOLED TO 300 K OVER THE COURSE OF 20 PS USING CONVENTIONAL CARTESIAN DYNAMICS FOLLOWED FINALLY BY 10000 STEPS OF CONJUGATE GRADIENT ENERGY MINIMIZATION. THE NOE ENERGY TERM WAS 150 KCAL PER MOL FOR THE FIRST THREE STEPS AND 100 KCAL PER MOL FOR THE LAST. THE DIHEDRAL RESTRAINT TERM WAS 100 KCAL PER MOL FOR THE FIRST THREE STEPS AND 300 KCAL PER MOL FOR THE LAST. TWO HUNDRED STRUCTURES WERE CALCULATED, AND THE LOWEST 40 STRUCTURES WERE FURTHER REFINED BY USING THE SANDER MODULE OF AMBER 8.0 MOLECULAR MODELING SUITE. THE SOLVENT WAS REPRESENTED BY GENERALIZED-BORN GB SOLVENT MODEL. THE STRUCTURES WERE FIRST ENERGY MINIMIZED FOR1 PS WITHOUT ANY RESTRAINTS FOLLOWED BY 40 PS SIMULATED ANNEALING FROM 400 K TO 0 K WITH ALL THE RESTRAINTS. THE DISTANCE AND ANGLE RESTRAINTS WERE REPRESENTED BY A SQUARE-WELL PENALTY FUNCTION WITH FORCE CONSTANTS OF 20 KCAL PER MOL AND 2 KCAL PER MOL, RESPECTIVELY.	1
