Additional NMR Experimental Information
Details	THESE STRUCTURES WERE DETERMINED WITH NOE RESTRAINTS FROM MULTIDIMENSIONAL HETERONUCLEAR EXPERIMENTS, DIHEDRAL ANGLE RESTRAINTS BASED ON MEASUREMENTS OF SCALAR COUPLING CONSTANTS, AND DIPOLAR COUPLING RESTRAINTS MEASURED ON SAMPLES IN PARTIALLY ALIGNED PHASES. THE STRUCTURES ARE ARRANGED IN ORDER FROM LOWEST TO HIGHEST X-PLOR ENERGY.
