Calcium is an essential cofactor in the oxygen-evolving complex (OEC) of photosystem II (PSII). The removal of Ca2+ or its substitution by any metal ion except Sr2+ inhibits oxygen evolution. We used steady-state enzyme kinetics to measure the rate o

The O 2 –evolving complex of photosystem II catalyses the light–driven four–electron oxidation of water to dioxygen in photosynthesis. In this article, the steps leading to photosynthetic O 2 evolution are discussed. Emphasis is given to the pr

Carotenoids are known to function as light-harvesting pigments and they play important roles in photoprotection in both plant and bacterial photosynthesis. These functions are also important for carotenoids in photosystem II. In addition, beta-carote
