Fd acquires electrons from Photosystem I and transfers these to the FNR prosthetic group, FAD. Definition of Photosystem II. Plant-type ferredoxins in Arabidopsis transfer electrons from the photosystem I to multiple redox-driven enzymes involved in the assimilation of carbon, nitrogen, and sulfur. Cellular responses can be placed in different phases after salt application. 8). The gene termed 'sir' was detected by heterologous Southern hybridisation with the structural gene cysI from Escherichia coli encoding the iron-sulphur haemoprotein of the NADPH:sulphite reductase. The "fate of the electron" from reduced Fd (brown) is focused here and it involves a plethora of electron acceptors on the stromal side of the membrane. We pinpoint endogenous ETCs from plant organelles as power supplies to support nitrogenase for future engineering of diazotrophy in cereal crops. Replacement of any one of these basic residues produced a much more pronounced effect on the cytochrome c reductase activity, where FNR, reduced by NADPH, acted as electron donor, than in the reduction of NADP+ by photosystem I via FNR.
