Additional NMR Experimental Information
DetailsThis structure was determined using: 1. distance restraints collected from 3D NOESY experiments, 2. dihedral angle restraints based on coupling constants (HNHA), and chemical shift data (CSI, TALOS), 3. hydrogen-bond restraints (collected from H-D exchange measurements), 4. 1H-15N residual dipolar couplings
