FIGURE 8.
1H-NMR NOESY spectra of unmodified ASLLysUUU with additions of YrdC and ATP. The spectra were collected in 10% D2O at 25°C. A region of the ASLLysUUU spectrum (7.4–8.4 ppm × 5.4–6.0 ppm) is practically free of overlapping resonances from the protein. The connectivities between the ASLLysUUU aromatic protons and the H1′ of the ribose are annotated: black, unmodified ASLLysUUU alone; blue, addition of YrdC; and red, addition of ATP to YrdC and the ASL.
