NMR spectral characterization of AID fragments. (A) Backbone resonance assignments of 15N-labeled AID in the 2D 1H-15N HSQC spectrum. (B) Spectral comparison in a region of the 2D 1H-15N HSQC spectra for nonphosphorylated (red) and phosphorylated AID (blue). The backbone amide signals of the phosphorylated Ser shows an upfield shift in both the 1H and 15N dimensions. (C) Comparison of the 15N{1H} heteronuclear NOE profiles between nonphosphorylated (red) and phosphorylated (blue) AID fragments.
