Electron transport to nitrogenase in Rhodospirillum rubrum: identification of a new fdxN gene encoding the primary electron donor to nitrogenase.
In our efforts to determine the components participating in the electron transport to nitrogenase in Rhodospirillum rubrum, we have identified a gene encoding a new ferredoxin. We have generated mutants in both the new ferredoxin and ferredoxin I and demonstrate that the new ferredoxin, FdN and not the previously identified FdI is the main donor of electrons to nitrogenase.
