Survey on nitrogenase evolution by considering the importance of nitrogenase, its structure, and mechanism of nitrogenase

open access: yesNotulae Botanicae Horti Agrobotanici Cluj-Napoca
Nitrogenase is a complicated enzyme that actives the ATP-dependent reduction of dinitrogen (N2) to ammonia (NH3). The aim of this manuscript is to review the nitrogenase evolution with considering nitrogenase, structure of nitrogenase, action mechanism ...

Biosynthesis of Nitrogenase Cofactors [PDF]

open access: yesChemical Reviews, 2020
48 Pág.Nitrogenase harbors three distinct metal prosthetic groups that are required for its activity. The simplest one is a [4Fe-4S] cluster located at the Fe protein nitrogenase component.

NifA is the master regulator of both nitrogenase systems in Rhodobacter capsulatus

open access: yesMicrobiologyOpen, 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

Regulatory response to a hybrid ancestral nitrogenase in Azotobacter vinelandii

open access: yesMicrobiology 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

A critical role of an oxygen-responsive gene for aerobic nitrogenase activity in Azotobacter vinelandii and its application to Escherichia coli

open access: yesScientific Reports, 2022
Since nitrogenase is irreversibly inactivated within a few minutes after exposure to oxygen, current studies on the heterologous expression of nitrogenase are limited to anaerobic conditions.

Potential of Phototrophic Purple Nonsulfur Bacteria to Fix Nitrogen in Rice Fields

open access: yesMicroorganisms, 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 ...

Response strategies of N-fixation by epiphytic bryophytes to water change in a subtropical montane cloud forest

open access: yesEcological Indicators, 2022
Water changes are predicted to regulate physiological activities of bryophytes characterized by poikilohydric gametophytes. In montane forest ecosystems, nitrogen(N)–fixing bryophyte–cyanobacteria associations are main N resources.

Nitrogenase Fe Protein: A Multi-Tasking Player in Substrate Reduction and Metallocluster Assembly

open access: yesMolecules, 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 ...

Heterologous expression of a fully active Azotobacter vinelandii nitrogenase Fe protein in Escherichia coli

open access: yesmBio, 2023
The functional versatility of the Fe protein, the reductase component of nitrogenase, makes it an appealing target for heterologous expression, which could facilitate future biotechnological adaptations of nitrogenase-based production of valuable ...
