DISTANCE GEOMETRY SIMULATED ANNEALING	THE STRUCTURES ARE BASED ON A TOTAL OF 62 RESTRAINTS, 60 ARE NOE-DERIVED DISTANCE CONSTRAINTS, 2 DIHEDRAL ANGLE RESTRAINTS. THE 31 STRUCTURES WERE DIVIDED INTO TWO FAMILIES OF SIMILAR ENERGY WHICH ESSENTIALLY DIFFER IN THE NUMBER AND TYPE OF TURNS. THE TWO FAMILIES ARE S'1 (STRUCTURES 1-14) AND S'2 (STRUCTURES 15-31).	X-PLOR 3.851, CHARMM 22
