From: Functional modulation of LHCSR1 protein from Physcomitrella patens by zeaxanthin binding and low pH

Fluorescence quantum yield at different pH and detergent concentrations of LHCII as compared to LHCSR1 control and de-epoxidized. Distributions of fluorescence quantum yields at the different detergent concentrations were fitted with sigmoidal functions.
