Dependence of Chlorophyll Fluorescence Polarization on the Membrane Fluidity in Isolated Photosystem II
The changes in the fluidity of the membranes affect the spatial arrangement of the membrane proteins. Mobility of the membrane protein and its organization are probably influenced by the motional characteristics of the lipids in the boundary region of the proteins (1). The physical state of lipids in biomembranes affects the protein dynamics (2,3). Low levels of cholesterol cause a decrease in the fluidity of the thylakoid membranes and brings about a significant inhibition of the interaction between electron transport components (4).
