The structure is based on a total of 236 constraints, 226 are NOE-derived distance constraints, 8 dihedral constraints, 2 constraints from one hydrogen bonds s, using distance geometry, simulated annealing by CYANA 2.1 soft to determine the structure, and using molecular dynamics mothod to do the structurn refinement by AMBER 9.0. | XwinNMR |
