NifA is the master regulator of both nitrogenase systems in Rhodobacter capsulatus
MicrobiologyOpen, 2019 Rhodobacter capsulatus fixes atmospheric nitrogen (N2) by a molybdenum (Mo)‐nitrogenase and a Mo‐free iron (Fe)‐nitrogenase, whose production is induced or repressed by Mo, respectively. At low nanomolar Mo concentrations, both isoenzymes are synthesized

Genetic analysis of the NifM dependence of the nitrogenase iron proteins [PDF]
mBioNifH maturation in certain diazotrophic bacteria depends on NifM, a protein with a PpiC-isomerase domain. Intriguingly, the putative proline substrate for NifM is present in NifH proteins from strains lacking nifM, raising questions regarding the actual ...

Regulatory response to a hybrid ancestral nitrogenase in Azotobacter vinelandii
Microbiology Spectrum, 2023 Biological nitrogen fixation, the microbial reduction of atmospheric nitrogen to bioavailable ammonia, represents both a major limitation on biological productivity and a highly desirable engineering target for synthetic biology. However, the engineering

Potential of Phototrophic Purple Nonsulfur Bacteria to Fix Nitrogen in Rice Fields
Microorganisms, 2021 Biological nitrogen fixation catalyzed by Mo-nitrogenase of symbiotic diazotrophs has attracted interest because its potential to supply plant-available nitrogen offers an alternative way of using chemical fertilizers for sustainable agriculture ...

Nitrogenase Fe Protein: A Multi-Tasking Player in Substrate Reduction and Metallocluster Assembly
Molecules, 2022 The Fe protein of nitrogenase plays multiple roles in substrate reduction and metallocluster assembly. Best known for its function to transfer electrons to its catalytic partner during nitrogenase catalysis, the Fe protein is also a key player in the ...
