Abstract
A model of heme–quinone redox interaction has been developed for cytochrome b559 in photosystem II. The quinone QC in the singly protonated form may function as an interacting quinone. The electrostatic effect between the charges on the heme iron of the cytochrome and QCH leads to appearance of three forms of the cytochrome with different redox potentials. A simple and effective mechanism of redox regulation of the electron transfer pathways in photosystem II is proposed.
