Figure 7. Circular dichroism and ¹H 1D NMR spectrum of designed proteins.

(A, F) hnRNPK; (B, G) thioredoxin; (C, H) CISK-PX; (D, I) Lov2; (E, J) TIF1 domains. The first column represents CD data, with X-axis representing the wavelength of circular polarized light (nm) and Y-axis the mean residue ellipticity measured in degree cm² dmol⁻¹. The second column consists of ¹H 1D NMR spectra, with chemical shifts given in ppm on the X-axis. The arrows indicate key methyl chemical shifts indicated of a stable protein fold.
