MethodDetailsSoftware
simulated annealingThe structure was obtained using triple resonance NMR spectroscopy. GFT_NMR experiments were used for backbone resosnance assignments and conventional 3D TOCSY experiments were used for sidechain assignments. Automated NOESY assignments were made using AUTOSTRUCTURE and CYANA-3.0 software. Dihedral angle constraints were obtained using TALOS. The structure calculation was done excluding the 8-residue C-terminal tag (LEHHHHHH). Final structure quality factor excluding C-terminal tag: as determined by PSVS-v1-4: Ordered residues are defined as 5-71, 74-114. (a) RMSD (ordered residue) all backbone atoms - 0.7A, heacyatoms - 1.1A. (b) Ramachandran statistics for ordered residues: Most favored region: 85.1%, additionally favored: 14.6%, Generously allowed: 0.4%. (c) Procheck scores for ordered residues (RAW/Z): Phi/psi - -0.42/-1.34, all - -0.40/-2.37. (d) MolProbity clashscores (RAW/Z) - 21.86/-2.23. (e) RPF scores for the goodness fit to NOESY data: Recall - 0.917, Precision - 0.928, F-measure 0.923 and final dp-score - 0.755.CNS
