Additional NMR Experimental Information
1 The minimized average structure is model 1. Models 2-26 are the the final 25 conformer ensemble. DYANA and CNS were used for refinement. VIRTUALLY COMPLETE RESONANCE ASSIGNMENTS WERE REPORTED I (2001) J.Biom.NMR, 19: 289-90; Stereo-specific assignments for all the methyl groups of of the eight Leu residues and for the alpha-methylene pr eight Gly, 46 beta-methylene protons and the gamma-methy of the seven Ile were available. In total, 1879 experim were employed, representing ~19 constraints per residue. structures was first calculated with DYANA, based on 114 92 hydrogen bond distances and 193 dihedral angles. Ref values yielded an esemble of 50 structures exhibiting at 0.26+/-0.06 A and 0.64+/-0.08A with respect to the mean backbone (N,CA,C') and all heavy atoms, respectively, an 0.81+/-0.10A^2. This initial ensemble of structures was residual dipolar couplings (80) and chemical shifts (291 programs CNS. Overall, excellent agreement with the exp good covalent geometry was maintained throughout. The f was selected and are presented here as MODELS2-26, and a mean structure of this ensemble is presented here as MOD.
