Abstract

The bimolecular interaction between Plastocyanin and Photosystem I under steady-state illumination was studied. The dependence of the O 2 consumption rate on Plastocyanin concentration, electrostratic effect in the presence of mono- and divalent cations and pH-dependence were investigated. A mechanism of activating complexes formation between Plastocyanin and Photosystem I in frame of trimeric structure of Photosystem I is proposed.
