NMR Refinement
Method	Details	Software
simulated annealing	The structure of two functional domain of the protein is calculated based on their NOE-derived distance constraints, hydrogen bonds and dihedral angle restraints. The paramagnetic relaxation enhancement from spin-labeling experiments and inter-domain NOE help define the structure of full protein.	VnmrJ
