| DISTANCE GEOMETRY AND SIMULATED ANNEALING. | STRUCTURES ARE BASED ON 2961 INTERPROTON DISTANCE RESTRAINTS DERIVED FROM NMR MEASUREMENTS INCLUDING 138 HYDROGEN BOND RESTRAINTS FROM 69 HYDROGEN BONDS IDENTIFIED USING AMIDE EXCHANGE DATA AND INITIAL STRUCTURE CALCULATIONS. IN ADDITION, 83 PHI BACKBONE TORSION ANGLE RESTRAINTS WERE DERIVED FROM COUPLING CONSTANTS. THE METHOD USED TO DERIVE THE FINAL ENSEMBLE OF STRUCTURES IS THE HYBRID METRIC MATRIX DISTANCE GEOMETRY-DYNAMICAL SIMULATED ANNEALING METHOD (M. NILGES, G.M. CLORE, AND A.M.
