NMR Refinement
Method	Details	Software
molecular dynamics	Refinement was done in two steps: first in vacuo and then with explicit micelle/water system. The pseudo atoms labeled ANI are included in the constraint file. These define an alignment frame used in the structural interpretation of rdc data.	TopSpin
