Abstract
Chloride is an indispensable factor for the functioning of oxygen evolving complex (OEC) and has protective and activating effects on photosystem II. In this study we have investigated mainly by EPR, the properties of chloride-sufficient, chloride-deficient and chloride-depleted thylakoid membranes and photosystem II enriched membranes from spinach. The results on the effects of different chloride depletion methods on the structural and functional aspects of photosystem II showed that chloride-depletion by treating PS II membranes with high pH is a relatively harsh way causing a significant and irreparable damage to the PS II donor side. Damage to the acceptor side of PS II was recovered almost fully in chloride-deficient as well as chloride-depleted PS II membranes.Entities:
