Modulation of the Hill Reaction Rates by Ions Interacting with the Outer Surface of Cyanobacterial Thylakoids

  • G. Sotiropoulou

Polypeptide-complexed ions (Mn2+ , Ca2+ , Cl ) are indispensible components of the hydrophilic domain of the photosystem II complex of higher plants and probably of cyanobacteria (reviewed by Ghanotakis and Yocum, ref. 1). In addition, many studies suggest that diffusible cations exert a controlling influence on photoinduced electron transport in oxygenic plant thylakoids. Particularly prominent is the role of cations in cyanobacteria.
