Table 2.

The number of residues for which the relaxation data was analyzed by the given model in model-free analysis.

Model	WT and Mut^#	WT only^##	Mutant only^##
Standard model (S² and τ_i)	53	3	5
Extended model (S²_f, S_s², τ_i)	12	2	0
Exchange model (S², τ_i, R_ex)	14	0	1

When an R₂, R₁, and hNOE dataset of a residue from one of the two proteins required an extended or exchange model, the dataset from the other protein was analyzed using the same model.

^##

“Only” indicates that an R₂, R₁, and hNOE dataset was obtained only for one of the proteins for a residue.
