simulated annealing	THE FINAL STRUCTURES ARE BASED ON A TOTAL OF 1750 CONFORMATIONALLY-RESTRICTING NOE-DERIVED DISTANCE CONSTRAINTS AND 125 DIHEDRAL ANGLE CONSTRAINTS; 0 HYDROGEN BOND CONSTRAINTS (22.1 CONSTRAINTS PER RESIDUE, 6.4 LONG RANGE CONSTRAINTS PER RESIDUE, COMPUTED FOR RESIDUES 147 TO 232 BY PSVS 1.4). STRUCTURE DETERMINATION WAS PERFORMED ITERATIVELY USING CYANA 3.0. THE 20 STRUCTURES OUT OF 100 WITH THE LOWEST TARGET FUNCTION WERE FURTHER REFINED BY RESTRAINED MOLECULAR DYNAMICS/ENERGY MINIMIZATION IN EXPLICIT WATER (CNS) WITH PARAM19.	CNS
