1H-NMR and fluorescence spectroscopic studies on the interaction between the Trp-Leu-Glu and m7GpppA have shown a specific binding mode, in which the pi-pi stacking interaction of the Trp indole ring and the hydrogen-bond pairing of Glu carboxyl side group with 7-methylguanine base are simultaneously formed.
