NMR Refinement
Method Distance geometry/Simulated annealing, followed by restrained molecular dynamics. The stereospecific assignments of the L10 methyl groups were determined by relaxation-matrix NOE backcalculation.
Details Structures are based on 265 interresidue NOE-derived distance constraints, 27 dihedral angle restraints, and 10 hydrogen bond restraints.

Additional NMR Experimental Information
1 This structure was determined using 2D and 3D homonuclear techniques.Stereospecific assignments for the L18 methyl groups could not be unambiguously determined. However, the resonances were clearly resolved. As a result,the structures were calculated as two families, depending on the assignments used. Structures 1-15 belong to one family, and use the assignments indicated in the accompanying restraint file. Structures 16-30 use the opposite assignments for the L18 methyls.
