Method distance geometry, molecular dynamics
Details The structures are based on 91 distance restraints and 26 dihedral angle restraints. None of the final structures have violations > 0.07A or 1.0 degrees. The mean rmsd to the mean coordinates for heavy atoms of residues Cys3 to Tyr15 is 0.31+/-0.06 A.
NMR Ensemble Information
Conformer Selection Criteria structures with the least restraint violations
Conformers Calculated Total Number 80
Conformers Submitted Total Number 20
Representative Model Choice Rationale
1 closest to the average,fewest violations,lowest energy,minimized average structure
Additional NMR Experimental Information
1 This structure was determined using standard 2D homonuclear techniques to generate distance (ROESY) and dihederal angle (DQF-COSY, COSY-35)restraints. Additional dihedral angle restraints were derived from chemical shift information using the program TALOS
