Figure 3.7 Hydrophobin rodlets experience a significant increase in

β

-sheet structure upon assembly. (a) Circular dichroism spectra
of EAS in water (dotted line) and dried onto a quartz cuvette
(solid line). The minimum shifts from 200 to approximately
210 nm upon rodlet formation indicating the presence of
β

-sheet structure. (b) Attenuated total reflectance Fourier
transform infrared spectra of SC3 under two conditions: non-
assembled SC3 deposited onto a germanium plate (dark thick
line) and vortexed SC3 on a germanium plate (dotted line).
A shift to the lower wavelengths of approximately 1630 nm
(indicative of the presence of mainly -sheet structure) can

be seen in the vortexed sample. Vertical scale is arbitrary.
