Abstract
The chlorophyll-protein complexes — within the membrane framework — bear the fundamental primary functions of the photosynthetic apparatus in vivo. Therefore not only pigment-pigment, but also pigment-protein interactions should be involved in the differentiation and functional specialization of chlorophyll. Any pigment molecule in the protein environment can be influenced by i) physical factors (e.g. variation of dielectric constant); ii) field of the charged groups in the polypeptide side chains (Lys, Glu, Asp); iii) fixation by weak (hydrophobic, π — π) or iv) strong (coordination) interactions. Here the coordination unsatu-ration of the central Mg atom or the hydrogen-bond capabilities of the chlorophyll carbonyls can be used for the contact with suitable protein groups. All these interactions can modify the chlorophyll physical properties (electronic levels in particular). Such an altered pigment is then involved in the cooperative estabilishment of the final conformation of the complex, resulting in the optimal geometry adjustment of the chlorophyll molecules, necessary for the proper function of the system. In this sense the protein influences also the pigment-pigment interactions. The aim of our work was to study the manifestation of several above mentioned chlorophyll-protein interactions in the pigment properties, using specialy prepared model sy stems.
