Figure 2. The F978A mutation in eIF4G HEAT-1 affects binding to eIF4A, but not to eIF4A-CTD.
(A, B) Overlay of SPR sensorgrams showing binding of eIF4A to immobilized WT eIF4G HEAT-1 (A) and eIF4G HEAT-1 F978A
(B). (C, D) SPR graphs showing binding of full-length eIF4A (C) and eIF4A-CTD (D) to immobilized WT eIF4G HEAT-1 (black) and HEAT-1 F978A (red). KD values marked with a star should be considered only estimates, since concentrations higher than the KD could not be reached in the titration due to limited solubility.
