HYBRID DISTANCE GEOMETRY DYNAMICAL SIMULATED ANNEALING	THE FAMILY OF 23 STRUCTURES IS SUPERIMPOSED OVER THE WELL-DEFINED HELICAL REGION ENCOMPASSING RESIDUES 4 - 16 AND 24 - 34. THE AVERAGE RMSD'S BETWEEN THE 23 REFINED STRUCTURES AND AVERAGE STRUCTURE ARE AS FOLLOWS: 0.81 (RESIDUES 4 - 16 AND 24 - 34, BACKBONE ATOMS) 1.48 (RESIDUES 4 - 16 AND 24 - 34, HEAVY ATOMS) 1.08 (ALL BACKBONE ATOMS) 1.77 (ALL HEAVY ATOMS).
