CRC 1078/1: Structural Basis of Proton Release in Water Oxidation by Photosystem II (SP A05)
Zouni, Athina, (Experimental Biophysics)
Duration of project: 01/2013 - 03/2021
In oxygenic photosynthesis, water is oxidized and dioxygen is formed at the Mn4Ca complex of photosystem II (PSII), a 750 kDa protein-cofactor complex embedded in the thylakoid membrane of plants and cyanobacteria. Reliable structural models of PSII ...
