NMR Refinement
Method	Details	Software
simulated annealing	The structures cannot be superimposed as a entire molecule due to the flexible linker. It's only can be superimposed in the WW domain region respectively. Taking each domain individually(6-32AA and 47-73AA), the r.m.s.d. values close is to 0.4 for backbone.	Sparky
