NMR chemical shift perturbation of LBD FTZ-F1 by GCECPEP.15 N HSQC spectra of 100 mM LBD FTZ-F1 in the absence (blue) and presence (red) of GCECPEP. The observed chemical shift perturbation indicates the interaction of LBD FTZ-F1 with a selected fragment (NR box) of GCEC. A selection of the most perturbed cross peaks is marked
