Figure 7

(a) Structure of the idealized turn/β-sheet structure. Residues in the turn are labeled in red, and those in the β-sheet are labeled in blue. (b) Simulated FTIR spectrum for the idealized turn/β-sheet structure. The top panel shows the contribution of each residue to the corresponding spectral features in a 2.7 cm–1 window. The bottom panel includes normalized FTIR and stick spectra for the turn/β-sheet structure. Simulated parallel (a) and perpendicular (b) 2D IR spectra for the structure in part a are plotted with boxes designating features due to the β-sheet (box A), turn (box B), and turn/β-sheet cross-peak (boxes xAB and xAB′).
