| DISTANCE GEOMETRY, RESTRAINED ENERGY REFINEMENT | FOR THE PRESENT STRUCTURES THE NMR DISTANCE CONSTRAINTS WERE WEIGHTED SUCH THAT A VIOLATION OF AN UPPER DISTANCE LIMIT OF 0.1 ANGSTROM CORRESPONDS TO AN ENERGY OF KT/2. THE CONSTRAINTS ON DIHEDRAL ANGLES RESULTING FROM MEASUREMENTS OF VICINAL COUPLING CONSTANTS WERE WEIGHTED SUCH THAT A VIOLATION OF 2.5 DEGREES CORRESPONDS TO AN ENERGY OF KT/2. | OPAL |
