Binding interface of p75^NTR-DD:TRADD-DD complex.A, representative slice from the ¹³C,¹⁵N-filtered 3D NOESY spectrum. ∗, ambiguous NOE peaks. The p75^NTR-DD was labeled with ¹³C and ¹⁵N, and the TRADD-DD was unlabeled. B, detail of binding interface in the p75^NTR-DD:TRADD-DD complex. Key residues at the binding interface are labeled and depicted as stick models. Close distances between nitrogen and oxygen atoms (~5 Å or less) are showed in dash lines.
