THE STRUCTURE WAS DETERMINED USING TRIPLE RESONANCE NMR SPECTROSCOPY. AUTOMATED BACKBONE ASSIGNMENTS WERE MADE USING AUTOASSIGN, AND THE SIDE CHAIN ASSIGNMENTS WERE COMPLETED MANUALLY. AUTOMATIC NOESY ASSIGNMENTS WERE DETERMINED USING CYANA 2.1. DIHEDRAL ANGLE CONSTRAINTS WERE OBTAINED FROM TALOS. HYDROGEN BOND CONSTRAINTS WERE DETERMINED USING BOTH AUTOSTRUCTURE AND CYANA, AND WERE APPLIED ONLY IN THE FINAL REFINEMENT STAGE (CNS) OF THE STRUCTURE DETERMINATION. COMPLETENESS OF NMR ASSIGNMENTS (EXCLUDING C-TERMINAL HHHHHH): BACKBONE, 97.9%, SIDE CHAIN, 94.2%, AROMATICS, 91.8%, STEREOSPECIFIC METHYL, 100%, STEREOSPECIFIC SIDE CHAIN NH2: 83.3%. FINAL STRUCTURE QUALITY FACTORS (FOR RESIDUES 37 TO 162, PSVS 1.3), WHERE ORDERED RESIDUES [S(PHI) + S(PSI) > 1.8] COMPRISE: 38-58,61-93,96-113,118-124,128-159: (A) RMSD (ORDERED RESIDUES): BB, 0.5, HEAVY ATOM, 1.0. (B) RAMACHANDRAN STATISTICS FOR ORDERED RESIDUES: MOST FAVORED, 88.4%, ADDITIONALLY ALLOWED, 11.5%, GENEROUSLY ALLOWED, 0.1%, DISALLOWED, 0.0%. (C) PROCHECK SCORES FOR ORDERED RESIDUES (RAW/Z-): PHI-PSI, -0.46/-1.49, ALL, -0.27/-1.60. (D) MOLPROBITY CLASH SCORE (RAW/Z-): 18.98/-1.73. (E) RPF SCORES FOR GOODNESS OF FIT TO NOESY DATA (RESIDUES 37-162): RECALL, 0.985, PRECISION, 0.925, F-MEASURE, 0.954, DP-SCORE, 0.816. (F) NUMBER OF CLOSE CONTACTS PER 20 MODELS: 8. THE C-TERMINAL HIS TAG RESIDUES OF THE PROTEIN (HHHHHH) WERE NOT INCLUDED IN THE STRUCTURE CALCULATIONS AND HAVE BEEN OMITTED FROM THIS DEPOSITION. COORDINATES FOR THE FOLLOWING RESIDUES ARE NOT WELL DETERMINED [S(PHI) + S(PSI) < 1.8]: 37,59-60,94-95,114-117,125-127,160-162. |

STRUCTURE DETERMINATION WAS PERFORMED ITERATIVELY USING CYANA 2.1. 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, AND USING NEUTRAL HISTIDINES AT POSITIONS 119 and 131. | ||||||||||||||||||||||||||||||||||||||||||||||||||||
