Description of the research topic:
Cyanobacteria are a phylum of phototrophic bacteria, found in almost any habitat on the planet. They are the only prokaryotes capable of oxygenic photosynthesis and are important primary biomass producers and have great potential from biotechnological and industrial point of view. The photosynthetic apparatus of cyanobacteria shares many similarities with „green” photosynthetic organisms – algae and higher plants – employing two photosystems (PS I and PS II) working in tandem to drive photoinduced electron transport. However, light harvesting, i.e. the absorption of photons and the transfer of their energy to the photosystems, is organized differently – instead of the membrane-intrinsic chlorophyll-binding light-harvesting antenna proteins found in plants, cyanobacteria have large membrane-peripheral pigment-protein complexes, phycobilisomes, composed of phycobiliproteins. The interactions of the phycobilisomes and the membrane-intrinsic photosystems, the dynamics of energy transfer and its regulation are not fully understood. This project aims to investigate how different structural components of the cyanobacterial thylakoid membrane regulate the assembly, function and regulation of the light-harvesting apparatus. The research will depend on a combination of methods borrowed from microbiology, biotechnology, biochemistry and biophysics. The assembly of phycobilisomes and photosystems will be characterized by biochemical / physicochemical techniques and their interactions and the dynamics of energy exchange will be studied by optical spectroscopy in vivo and in vitro.
