MINIMAL CONSTRAINT STRUCTURE, CONTAINED 512 CONFORMATIONALLY RESTRICTING NOE-DERIVED DISTANCE CONSTRAINTS, 54 HYDROGEN BONDED PAIRS, 186 RESIDUAL DIPOLAR COUPLING CONSTRAINTS, 197 DIHEDRAL ANGLE CONSTRAINTS. 7.0 CONSTRAINTS PER CONFORMATIONALLY CONSTRAINED RESIDUE. 1.0 LONG RANGE CONSTRAINT PER RESIDUE.	DETERMINATION WAS PERFORMED WITH THE FOLLOWING STEPS: RESONANCE ASSIGNMENTS, TORTION ANGLE CONTRAINTS, HYDROGEN BONDED PAIRS AND NOESY CROSSPEAK DATA WAS USED AS INPUT INTO AUTOSTRUCTURE-DYANA. AUTOSTRUCTURE-DYANA IDENTIFIED DISTANCE CONSTRAINTS. THESE DISTANCE CONSTRAINTS WERE USED AS INPUT INTO AN XPLOR-NIH SIMULATED ANNEALING. USING CNS THE TOP TEN XPLOR-NIH STRUCTURES WERE ENERGY MINIMIZED IN EXPLICIT WATER WITH RDC CONSTRAINTS.	AUTOSTRUCTURE-DYANA
