Automated backbone resonance assignments were made using AUTOASSIGN and the sidechain assignments were completed manually. Automated NOESY assignments were made using AUTOSTRUCTURE and CYANA-2.1. Dihedral angle constraints were obtained from TALOS. The structure calculations were done excluding the six HIS from the 8-residue C-terminal tag(LEHHHHHH). Completeness of assignments excluding the HHHHHH: Backbone:100% Sidechain(aliphatic): 99% Sidechain (Aromatic): 90% Stereospecific Methyl assignments:100%. The assignments were validated using AVS software. Final structure quality factors(excluding the HHHHHH) determined using PSVS-v1.3: Ordered residues are defined as residues 2-28,33-34,37-69.(a) RMSD (ordered residues)all backbone atoms:0.4A, all heavy atoms: 0.7A; RMSD (all residues) backbone: 0.7A and heavy atoms: 1.0A. (b) Ramachandran statistics for ordered residues : Most favoured regions: 97.1%, additionally allowed regions: 2.9%.(C) PROCHECK SCORES FOR ORDERED RESIDUES (RAW/Z-): PHI-PSI,0.21/1.14, ALL,0.24/1.42 (D) MOLPROBITY CLASH SCORE (RAW/Z-): 17.26/-1.44. (E) RPF scores for the goodness of the fit to NOESY data: Recall:0.984, PRECISION: 0.848, F-measure: 0.911 and final DP-score:0.743. (f) Number of close contacts for 20 models: 6. RMS deviation for bond angles:0.6deg. RMS deviation for bond lengths 0.008A. | ||||||||||||||||||||
