Fig. 11. PrOF NMR studies characterizing structure and dynamics of Bcl-xL and lectin CV-N. (A) ¹⁹F–¹⁹F NOESY spectra of 4FF-Bcl-xL with a fluorinated ligand, protein–ligand complex crosspeaks circled (adapted from ref. 140 with permission from Springer, copyright 2006). (B) ¹⁹F NMR spectra of 4FF-MTSL labeled lectin CV-N reduced (black) and oxidized (magenta) at differing relaxation delays (adapted from ref. 146 with permission from Wiley-VCH, copyright 2016).
