Details The input for the final structure calculation of N-domain protein consisted of 1279 upper limit distance restraints and 358 dihedral angle restraints. 185 of the dihedral angle restraints reflected coupling constant information, while 173 of them had been derived by HABAS from NOE and steric restraints alone.
NMR Ensemble Information
Conformer Selection Criteria structures with the lowest energy,target function
Conformers Calculated Total Number 50
Conformers Submitted Total Number 20
Representative Model Choice Rationale
1 lowest energy. model #1 was best after dyana calculations, model #17 was best after opal refinement
Additional NMR Experimental Information
1 The signal assignment was determined using triple-resonance NMR spectroscopy. The structure was determined using standard 2D homonuclear techniques.
