ARIA (AMBIGUOUS RESTRAINTS IN ITERATIVE ASSIGNMENTS) AMBIGUOUS DISTANCE RESTRAINTS SIMULATED ANNEALING WITH TORSION ANGLE DYNAMICS	STARTING WITH AN ALMOST COMPLETE LIST OF CHEMICAL SHIFTS, THE PROGRAM ARIA ( AMBIGUOUS RESTRAINTS IN ITERATIVE ASSIGNMENT) CALIBRATES NOES, MERGES THE OBTAINED AMBIGUOUS DISTANCE RESTRAINTS FROM DIFFERENT NOE SPECTRA AND ASSIGNS THE NOE PEAKS IN AN ITERATIVE MANNER. FROM A TOTAL OF 1890 NOES ABOUT 85% WERE MANUALLY ASSIGNED, THE REMAINDER WAS ASSIGNED BY ARIA. FLOATING POINT CHIRALITY ASSIGNMENT WAS USED DURING THE STRUCTURE CALCULATION IN ORDER TO OBTAIN STEREOSPECIFIC ASSIGNMENTS FOR METHYL AND METHYLENE GROUPS. THEREFORE, SOME METHYL AND METHYLENE CARBON/PROTON ATOM NAMES IN THE RESTRAINT FILES MIGHT BE INCONSISTENT COMPARED TO THOSE IN THE COORIDINATE FILES. THE DEPOSITED STRUCTURES HAVE BEEN WATER-REFINED AS DESCRIBED IN THE PUBLICATION. PSI REFINEMENT: THE STRUCTURES HAVE BEEN DIRECTLY REFINED AGAINST CROSS- CORRELATED RELAXATION RATES (C-ALPHA-H-ALPHA DIPOLE, CO CSA) AND THE THREE- BOND H/D ISOTOPE EFFECT ON THE C-ALPHA CHEMICAL SHIFT.
