Figure Lengend Snippet: Figure 2. C-terminal of a-syn plays a major role in the binding with vRAGE (A) Overlay of the 2D 1H-15N HSQC spectra of a-syn monomer alone (black) and that titrated by vRAGE (blue) at a molar ratio of 1:2 (a-syn:vRAGE). The cross- peaks of the negatively charged residues with significant CSDs (CSDs > 0.01 ppm) at the C terminus of a-syn are highlighted with black boxes and zoomed in on the top right. Experiments were performed two independent times. (B) Residue-specific CSDs of a-syn monomer titrated by vRAGE from (A). The domain organization of a-syn is shown on the top. The primary sequence of a-syn C terminus (residues 101–140) is shown, and the acidic residues are colored in red. The residues with CSDs >0.01 ppm are highlighted in blue.
