Chemical shift changes of uniformly 15N-labeled eRF3a(51–102) upon addition of PABC. (A) Overlay of the 1H–15N HSQC spectra of 15N-labeled eRF3a(51–102) in the absence (black) and presence (red) of PABC. (B) The chemical shift changes are plotted versus the residue number of eRF3a. Signals from residues 70–92 disappeared upon addition of PABC.
