Fluorescence spectroscopy. Fluorescence was measured in a Cary Eclipse fluorescence<br />

spectrophotometer equipped with a temperature control device <strong>and</strong> a multicell sample holder<br />

(Varian instrument Inc.).<br />

Ultraviolet-visible spectroscopy. UV-vis data were acquired by using a spectrophotometer DU<br />

series 640, Beckman Coulter, (Fullerton, CA) operating at 190-110 nm.<br />

Far <strong>and</strong> near-ultraviolet circular dichroism spectroscopy. CD spectra were obtained using a<br />

JASCO-715 automatic recording spectropolarimeter (Jasco, Tokyo, Japan) with a JASCO PTC-<br />

343 Peltier-type thermostated cell holder. Quartz cuvettes with 0.2cm pathlength were used.<br />

CD spectra were recorded between 195 <strong>and</strong> 300 nm at 25 0 C.<br />
