SPECTRA FOR BACKBONE AND SIDE CHAIN ASSIGNMENTS WERE OBTAINED ON A 1.7-MM MICROCRYOPROBE AT 600 MHZ. ALL NOESY DATA WERE ACQUIRED AT 800 MHZ USING A 5-MM CRYOPROBE. BACKBONE ASSIGNMENTS WERE MADE USING PINE, AND THE SIDE CHAIN ASSIGNMENTS WERE COMPLETED MANUALLY. AUTOMATIC NOESY ASSIGNMENTS WERE DETERMINED USING CYANA 3.0. BACKBONE (PHI/PSI) DIHEDRAL ANGLE CONSTRAINTS WERE OBTAINED FROM TALOSplus. COMPLETENESS OF NMR ASSIGNMENTS (EXCLUDING C-TERMINAL HHHHHH): BACKBONE, 94.5%, SIDE CHAIN, 89.5%, AROMATICS, 86.8%, STEREOSPECIFIC METHYL, 100%, STEREOSPECIFIC SIDE CHAIN NH2: 80.0%. FINAL STRUCTURE QUALITY FACTORS (FOR RESIDUE NUMBERS 1 TO 82, PSVS 1.4), WHERE ORDERED RESIDUES [S(PHI) + S(PSI) > 1.8] COMPRISE: 7-16,18-81: (A) RMSD (ORDERED RESIDUES): BB, 0.7, HEAVY ATOM, 1.3. (B) RAMACHANDRAN STATISTICS FOR ORDERED RESIDUES: MOST FAVORED, 91.8%, ADDITIONALLY ALLOWED, 8.1%, GENEROUSLY ALLOWED, 0.1%, DISALLOWED, 0.0%. (C) PROCHECK SCORES FOR ORDERED RESIDUES (RAW/Z-): PHI-PSI, -0.44/-1.42, ALL, -0.32/-1.89. (D) MOLPROBITY CLASH SCORE (RAW/Z-): 17.41/-1.46 (E) RPF SCORES FOR GOODNESS OF FIT TO NOESY DATA (RESIDUES 1-82): RECALL, 0.969, PRECISION, 0.904, F-MEASURE, 0.935, DP-SCORE, 0.797. (F) NUMBER OF CLOSE CONTACTS PER 20 MODELS: 7. THE C-TERMINAL HIS TAG RESIDUES OF THE PROTEIN (HHHHHH) WERE NOT INCLUDED IN THE STRUCTURE CALCULATIONS AND HAVE BEEN OMITTED FROM THIS DEPOSITION.

STRUCTURE DETERMINATION WAS PERFORMED ITERATIVELY USING CYANA 3.0. THE 20 STRUCTURES OUT OF 100 WITH THE LOWEST TARGET FUNCTION WERE FURTHER REFINED BY RESTRAINED MOLECULAR DYNAMICS/ENERGY MINIMIZATION IN EXPLICIT WATER (CNS) WITH PARAM19.
