DISTANCE GEOMETRY SIMULATED ANNEALING	OF 358 TOTAL RESTRAINTS, 311 ARE DISTANCE RESTRAINTS AND 47 ARE DIHEDRAL ANGLE RESTRAINTS. OF THE DISTANCE RESTRAINTS, 32 ARE HYDROGEN BOND RESTRAINTS (TWO PER H-BOND), 93 ARE SEQUENTIAL, 50 ARE MEDIUM RANGE, AND 136 ARE LONG RANGE. NO INTRARESIDUE DISTANCE RESTRAINTS WERE USED.	X-PLOR
