torsion angle dynamics	STRUCTURE BASED ON A TOTAL OF 1768 UNIQUE DISTANCE CONSTRAINTS (OBTAINED FROM 3044 NOE CROSSPEAKS), INCLUDING 355 INTRARESIDUE, 464 SHORT-RANGE, 445 MEDIUM RANGE AND 504 LONG-RANGE CONSTRAINTS. DYANA 1.5 ANNEAL COMMAND (10000 STEPS) USED TO GENERATE 40 CONFORMERS. 20 LOWEST TARGET FUNCTION STRUCTURES ANALYZED. CONFORMER 4 CHOSEN FOR DEPOSITION AS CLOSEST TO MEAN COORDINATES OF THE ENSEMBLE.
