Figure 7. CD spectra αB-Conotoxin VxXXIVA isomers.

Figure 7

(A) Overlay of spectra in phosphate buffer. (B) CD spectrum of αB-VxXXIVA [1], [2] in the presence of 50 and 87% TFE. This isomer showed a propensity to adopt a partially helical conformation at high TFE concentrations as evident by the shift in the minimum towards 208 nm along with some ellipticity developing around 222 nm.
