Abstract:
This chapter discusses the photosystem II (PSII) reconstitution into proteoliposomes. In the first part of the chapter, protocols are outlined for the preparation of lipid bilayer vesicles (liposomes) constituted of individual thylakoid lipids or their mixtures, for the preparation of PSII particles, and for the incorporation of the PSII particles into the liposomes. In the second part of the chapter, methodologies are described for the structure-function characterization of the PSII-lipid complexes (proteoliposomes). This includes the sodium dodecylsulfate-polyacrylamide gel electrophoresis determination of the PSII proteins, the measurement of oxygen-evolving activity of PSII in the proteoliposomes, the study of structural changes of the PSII proteins upon their incorporation into the lipid bilayers by Fourier transform infrared (FT-IR) spectroscopy, and the characterization of the PSII activity by fluorescence induction.

Functioning of Photosystems
Photosystems contain many pigment molecules, such as chlorophylls and carotenoids, arranged in a particular organization across two domains — the antenna complex and the reaction center. The main aim of the pigment molecules...
Photosystem I
Both these photosystems work in concert. An excited electron from PSII is relayed to PSI via an electron transport chain in the thylakoid membrane of the chloroplast, which is comprised of the carrier molecule plastoquinone, the dual-protein cytochrome complex, and plastocyanin. As electrons move between PSII and PSI, they lose energy and must be re-energized...
