sequence The mutation Y10L was created for structural studies. In addition, the P2T mutation and C- ...sequence The mutation Y10L was created for structural studies. In addition, the P2T mutation and C-terminal K, originally introduced in ZFY-6T (PDB entry 5ZNF) improve sample behavior without affecting structure.

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.

手法: Distance geometry, Simulated annealing, restrained molecular dynamics. The stereospecific assignments of the L10 methyl groups were determined by relaxation-matrix NOE backcalculation. ソフトェア番号: 1 詳細: Structures are based on 265 interresidue NOE-derived distance constraints, 27 dihedral angle restraints, and 10 hydrogen bond restraints.
