DISTANCE GEOMETRY SIMULATED ANNEALING
THE STRUCTURES ARE BASED ON A TOTAL OF 74 RESTRAINTS, 71 ARE NOE-DERIVED DISTANCE CONSTRAINTS, 3 DIHEDRAL ANGLE RESTRAINTS. THE 19 STRUCTURES WERE DIVIDED INTO TWO FAMILIES OF SIMILAR ENERGY WHICH ESSENTIALLY DIFFER IN THE NUMBER AND TYPE OF TURNS. THE TWO FAMILIES ARE S1 (STRUCTURES 1-12) AND S2 (STRUCTURES 13-19).
