Photosynthesis is a crucial energy conserving process supporting life on earth. In this process, accommodation of cyclic and linear electron flow (CET and LET, respectively) secures efficiency of reduction of CO2 into organic form. While molecular mechanisms of regulation between CET and LET remain largely unknown, cytochrome (cyt) b6f complex is considered to be a key point of it. We hypothesize that a newly discovered metastable radical intermediate of cyt b6f provides means for kinetic control to balance between LET and CET. From this perspective, we will seek to unravel structural basis and dynamics of interaction between cyt b6f and its plausible CET protein partners, define the sequence of electron transfer steps that engage cyt b6f into CET and describe thermodynamic basis for control of CET. This will provide fundamentals for understanding regulation of photosynthesis, as a step towards development of enhanced photosynthetic organisms to increase efficiency in plant production. (Polish)
