Figure 4. Figure 4. One-Dimensional Proton NMR of the N-Terminal Domain(A and C) Amide region.(B and D) Methylene region.The spectrum of the phosphorylated N-terminal domain is shown at the top (A and B) and that of the unphosphorylated N-terminal domain is at the bottom (C and D). Arrows point to spectral features that differ between the two forms of the domain.
