15N-relaxation-dispersion of TmNusGNTD-CTD. A) Selected 15N-relaxation-dispersion curves of residues from the domain interface (Gly312, Phe314), and Asp323 and Glu328. B) Structure of TmNusGNTD-CTD. Gly312, Phe314, Asp323, and Glu328 are shown in stick representation. C) Differences between transverse relaxation (R2) at the maiximum and minimum applied effective field for residues of the CTD. The residues located at the domain interface show no dependence of the inter-pulse delay during CPMG pulse trains, indicating the lack of dynamics on the μs-ms scale causing an exchange contributing to the transverse relaxation.
