DISTANCE GEOMETRY, SIMULATED ANNEALING, CHEMICAL-SHIFT AUTO -ASSIGNMENT, DISTANCE GEOMETRY, SIMULATED ANNEALING	SOFTWARE USED WAS CYANA AND ITS INTEGRATED AUTO-ASSIGNMENT MODULE CANDID. THE CHEMICAL SHIFT IDENTIFICATION TOLERANCE AND TRANSPOSE ERRORS WERE SET TO 0.015 PPM IN BOTH PROTON DIMENSIONS. STARTING WITH DISTANCE RESTRAINTS DERIVED FROM MANUALLY ASSIGNED NOE CROSS-PEAKS IN NMRVIEW, A TOTAL NUMBER OF 100 STRUCTURES WERE GENERATED PER CANDID ROUND WITH 8000 STEPS IN THE CYANA ANNEALING PROTOCOL. FOR EACH CANDID RUN, TALOS DERIVED ANGLE RESTRAINTS WERE INCORPORATED (WITH A MINIMUM ERROR SET MANUALLY TO 20 DEGREES) . THE BEST 20 LOW TARGET FUNCTION VALUE STRUCTURES OF CANDIDS FINAL ROUND WERE KEPT AS AN ENSEMBLE REPRESENTATION OF THE FAMILY OF GENERATED STRUCTURES.	CYANA
