DOI: 10.1016/j.gca.2018.07.024
Abstract: Abstract Oxygenic photosynthesis fundamentally transformed all major biogeochemical cycles and increased the size and complexity of Earth's biosphere. However, there is still debate about when this metabolism evolved. As oxygenic photosynthesis is the only significant… read more here.

DOI: 10.1016/j.tim.2021.05.008
Abstract: Cyanobacteria are the only prokaryotes to have evolved oxygenic photosynthesis, transforming the biology and chemistry of our planet. Genomic and evolutionary studies have revolutionized our understanding of early oxygenic phototrophs, complementing and dramatically extending inferences… read more here.

DOI: 10.1021/acsenergylett.8b00797
Abstract: The Z-scheme process in chlorophyll-based natural photosynthesis shows the pathway of photoinduced electron transport from photosystem II (PSII) to photosystem I (PSI) through an electron transfer chain. Inspired by the interesting Z-scheme of oxygenic photosynthesis,… read more here.

DOI: 10.1021/jacs.2c05857
Abstract: As the natural-born photoelectrolyzer for oxygen delivery, photosystem II (PSII) is hardly replicated with man-made constructs. However, building on the “quantasome” hypothesis (Science1964, 144, 1009−101117811607), PSII mimicry can be pared down to essentials by shaping… read more here.

DOI: 10.1089/ast.2021.0165
Abstract: In this hypothesis article, we propose that the timing of the evolution of oxygenic photosynthesis and the diversification of cyanobacteria is firmly tied to the geological evolution of Earth in the Mesoarchaean to Neoarchaean. Specifically,… read more here.

DOI: 10.2210/pdb6nbx/pdb
Abstract: Cyclic electron flow around photosystem I (PSI) is a mechanism by which photosynthetic organisms balance the levels of ATP and NADPH necessary for efficient photosynthesis1,2. NAD(P)H dehydrogenase-like complex (NDH) is a key component of this… read more here.
