Additional NMR Experimental Information

Details

The Structure was obtained using triple resonance NMR spectroscopy for backbone and side chain assignments. Automated NOESY assignments were made using Autostructure and CYANA3.0. Dihedral angle constraints were obtained using TALOS. The structure calculation was done excluding the 10-residue N-terminal tag. Completeness of assignment excluding the tag: Backbone - 80%, Sidechain - 80%. Peaks for 13 residues in NHSQC spectra are missing due to line broadening.
