Abstract

To undertake a thorough structural, biochemical and functional study of the newly discovered IsiA:Pcb light harvesting antenna ring of photosystem one in Oxyphotobacteria (Cyanobacteria and Prochlorophytes). Electron cryomicroscopy and possibly X-ray crystallography will be used to determine the 3D structure of the IsiA- PSI supercomplex of Synechocystis PCC 6803. The pigment composition of this supercomplex will be determined and its functional activities, energy transfer and electron transport properties investigated by optical and resonance spectroscopy. The chlorophyll b binding properties of the IsiA-PSI supercomplex will be investigated using a cao-plus mutant of Synechocystis and the result compared with the chlorophyll a:b binding properties of the Pcb-PSI supercomplex.
