Time drive measurements with full length Cph1.

<p>Absorbance at 710 nm (the absorbance maximum of Pfr) was measured continuously; at t = 0 s, R (400 µmol m⁻² s⁻¹) was switched on. The protein concentration of this sample differed slightly from that in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0109794#pone-0109794-g004" target="_blank">Fig. 4</a>.
