General Information | Comment | Organism |
---|---|---|
physiological function | FNR catalyzes the final step of the linear photosynthetic electron flow by mediating the electron transfer from reduced ferredoxin to NADP+ with formation of NADPH for CO2 assimilation or other biosynthetic pathways. This process is a rate-limiting step of photosynthesis under both limiting and saturating light conditions. FNR is also involved in the cyclic electron flow around photosystem I, cyclic PSI, by its photoproduct NADPH recycling to plastoquinone or the cytochrome b6f complex.
