NMR Refinement
Method SIMULATED ANNEALING
Details STRUCTURES WERE REFINED WITH MULTIPLE ROUNDS OF SIMULATED ANNEALING WITH THE ADDITION OF NEW NOES AND CORRECTION OF UNAMBIGUOUS NOES. PHI ANGLES WERE ONLY ADDED WHEN THEY AGREED WITH THE PURELY NOE DRIVEN CONVERGENCE OF THAT ANGLE IN INITIAL STRUCTURE CALCULATIONS. OTHER REFINEMENT INFORMATION CAN BE FOUND IN THE JRNL CITATION ABOVE.
NMR Ensemble Information
Conformer Selection Criteria STRUCTURES WERE SELECTED WITH NO VIOLATIONS > 0.3 A OR DIHEDRAL ANGLES > 0.5 A AND GOOD COVALENT GEOMETRY.
Conformers Calculated Total Number 40
Conformers Submitted Total Number 1
Additional NMR Experimental Information
1 RESONANCE ASSIGNMENTS WERE ACHIEVED USING STANDARD TWO- AND THREE-DIMENSIONAL SEQUENTIAL ASSIGNMENT TECHNIQUES. NMR RESTRAINTS WERE EXTRACTED FROM 50, 75 AND 150 MS NOESY EXPERIMENTS. COUPLING CONSTANTS WERE CALCULATED FROM AN HNHA EXPERIMENT WITH UNIFORMLY LABELLED EOTAXIN.
