NMR Refinement
Method	Details	Software
torsion angle dynamics	PCS were determined for 3 different attachment sites. During the refinement the tensor is updatexd in an iterative fashion as described by Cucuzza et al., JNMR 2020. Scaffold restraints are supplied by the regularization macro from CYANA. Three differnt starting sdtrucutres were refined, and for each, the strucutre with the lowest Q factor is submitted	CYANA
