The structure was determined using triple resonance NMR spectroscopy. Automated backbone resonance assignments were made using AUTOASSIGN and the side chain assignments were completed manually. Automated NOESY assignments were made using AUTOSTRUCTURE and CYANA-2.1. Dihedral angle constraints were obtained from TALOS. Completeness of assignments excluding the N-terminal tag-MGHHHHHHSH: backbone 100%, sidechain (aliphatic) 99%, sidechain (aromatic) 90%; stereospecific methyl assignments 100%. The assignments were validated using AVS software. Final structure quality factors were determined using PSVS-1.3; Ordered residues were defined as 12-19,22-82. RMSD (ordered residues) all backbone atoms: 0.5A, all heavy atoms: 0.8A. Ramachandran statistics for all ordered residues: most favoured 84.3%, additionally allowed 15.7%. Molprobity clashscore (raw/z-): 16.88/-1.37. Procheck scores for ordered residues: phi-psi, -0.50/-1.65, all, -0.19/-1.12
