A review on light/redox-dependent protein phosphorylation in thylakoids with emphasis on its relation to state transitions and protein turnover. The review describes the mechanism of the redox control of the kinase(s), requirement of a dynamic membrane organisation for kinase activation and the present state of enzyme identification.

Proc Natl Acad Sci USA 1997, 94:1585-1590. A novel mechanism for thylakoid protein phosphorylation redox control is presented. It involves a single plastoquinol molecule binding to the quinoloxidation site of the cytochrome bf complex with a reduced high potential path. The protein kinase activation and deactivation analysis included determination of the redox states of the electron transport components by low temperature electron paramagnetic resonance, laser flash photolysis, optical spectroscopy and inhibitor studies.
