Photosynthetic electron transport from water to NADP driven by photosystem II in inside-out chloroplast vesicles

Abstract

It is now widely held that the light-induced noncyclic (linear) electron transport from water to NADP(+) requires the collaboration in series of the two photosystems that operate in oxygen-evolving cells: photosystem II (PSII) photooxidizes water and transfers electrons to photosystem I (PSI); PSI photoreduces ferredoxin, which in turn reduces NADP(+) (the Z scheme). However, a recently described alternative scheme envisions that PSII drives the noncyclic electron transport from water to ferredoxin and NADP(+) without the collaboration of PSI, whose role is limited to cyclic electron transport [Arnon, D. I., Tsujimoto, H. Y. & Tang, G. M.-S. (1981) Proc. Natl. Acad. Sci. USA 78, 2942-2946]. Reported here are findings at variance with the Z scheme and consistent with the alternative scheme. Thylakoid membrane vesicles were isolated from spinach chloroplasts by the two-phase aqueous polymer partition method. Vesicles, originating mainly from appressed chloroplast membranes that are greatly enriched in PSII, were turned inside-out with respect to the original sidedness of the membrane. With added plastocyanin, ferredoxin, and ferredoxin-NADP(+) reductase, the inside-out vesicles enriched in PSII gave a significant photoreduction o...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Genetic Screens in iPSC-derived Brain Cells

Genetic screening is a critical tool that can be employed to define and understand gene function and interaction.
