Paper Abstract
LHCII is a largest plant photosynthetic antenna complex. Examination of monomolecular layers of LHCII. with Atomic
Force Microscopy reveals formation of regular ring-like structures composed of six trimers of the complex. FTIR
analysis of aggregated LHCII suggests that regular supramolecular structures of the complex are stabilized by hydrogen
bonding between the α helices C of neighboring trimers. Analysis of fluorescence emission spectra of LHCII-bound
chlorophyll a reveals that the aggregation is associated with formation of new electronic energy levels that can be
particularly important for both photosynthetic excitation energy transfer and quenching of excessive excitations under
overexcitation conditions.
