FIGURE 3.

Assignments of PepA1 NMR resonances. Superposition of extended regions of TOCSY (purple) and NOESY (black) spectra recorded in a 1:1.2 CDCl₃/CD₃OH ratio at 288 K, used to solve PepA1 three-dimensional structure. A, the NH-Hα cross-peaks are labeled in black when intraresidual and boxed in red for i/i+3 connectivities. B, the NH-NH assignment walk is displayed, showing that most of the C-terminal residues can be connected. Some i/i+2 NH-NH cross-peaks are boxed in red.
