Architectural study of photosynthetic complexes

Photosynthesis is a process by which the absorbed fight goves the sufficient energy to a reacton centre to split a water molecule, release oxygen, assimilate carbon dioxide and produce chemically fixed energy The Earth fundamental reaction that we know is mainly shaped due this fundamental reaction performed by cyanobacteria. On the larger scale, there are photosystems where the change separation takes place. On the small scale, there are large numbers of pigment molecules bound to these photosystems and their antenna complexes, which are involved in light absorption. There are two types of photosystems, Photosystem I (PSI) and Photosystem II (PSII) which are embedded in the thrylakpid membrane and are working in series. The goal of this thesis is to provide a structural and PSII complexes and their associations with light harvesting complexes, Lhca and LHC6 proteins respectively. The study of the architecture of supercomplexes is helpful for a better understanding of protein-protein interactions within the complex
