The Evolution and Evolvability of Photosystem II

open access: yesAnnual Review of Plant Biology, 2023
Photosystem II is the water-oxidizing and O2-evolving enzyme of photosynthesis. How and when this remarkable enzyme arose are fundamental questions in the history of life that have remained difficult to answer. Here, recent advances in our understanding of the origin and evolution of photosystem II are reviewed and discussed in detail.

Inactive photosystem II centers: A resolution of discrepencies in photosystem II quantitation

Photosynthesis Research, 1990
The abundance of photosystem II in chloroplast thylakoid membranes has been a contentious issue because different techniques give quite different estimates of photosystem II titer. This discrepancy led in turn to disagreements regarding the stoichiometry of photosystem II to photosystem I in these membranes.

Carotenoid Oxidation in Photosystem II

Biochemistry, 1999
The oxidation of carotenoid upon illumination at low temperature has been studied in Mn-depleted photosystem II (PSII) using EPR and electronic absorption spectroscopy. Illumination of PSII at 20 K results in carotenoid cation radical (Car+*) formation in essentially all of the centers.

Current perceptions of Photosystem II

Photosynthesis Research, 1990
In the last few years our knowledge of the structure and function of Photosystem II in oxygen-evolving organisms has increased significantly.
