Structural consequences of turnover-induced homocitrate loss in nitrogenase
Nature Communications, 2023 Nitrogenase catalyzes the ATP-dependent reduction of dinitrogen to ammonia during the process of biological nitrogen fixation that is essential for sustaining life.

Diazotroph-Derived Nitrogen Assimilation Strategies Differ by Scleractinian Coral Species
Frontiers in Marine Science, 2021 Reef-building corals generally thrive in nutrient-poor tropical waters, where among other elements, nitrogen (N) availability often limits primary productivity.

Fixation of Dinitrogen-15 Associated with Rice Plants [PDF]
Applied and Environmental Microbiology, 1980 Rice plants (IR26 and Latisail) obtained at near heading stage from a wetland field were transferred to water culture and exposed to 15 N 2 in a gas-tight growth chamber for 7 days to measure N 2 -fixing activities associated with the rice.

Scientific Reports, 2017 In the most studied rhizobium-legume interactions, the host plant supplies the symbiont with homocitrate, an essential co-factor of the nitrogenase enzyme complex, via the expression of a nodule-specific homocitrate synthase FEN1.

Methodological underestimation of oceanic nitrogen fixation rates. [PDF]
PLoS ONE, 2010 The two commonly applied methods to assess dinitrogen (N(2)) fixation rates are the (15)N(2)-tracer addition and the acetylene reduction assay (ARA). Discrepancies between the two methods as well as inconsistencies between N(2) fixation rates and biomass/

Angewandte Chemie, Volume 138, Issue 24, 8 June 2026.Association of the L‐cluster with the nitrogenase assembly proteins NifEN (NifENL) or NifB (NifBL) intrinsically endows these proteins with N2‐reducing activity, enabling in vitro N2‐reduction by NifENL and NifBL when supplied with chemical reductants or photoexcited quantum dots while supporting in vivo N2‐fixation in NifENL‐ and NifENL‐expressing ...

Planktonic Aggregates as Hotspots for Heterotrophic Diazotrophy: The Plot Thickens
Frontiers in Microbiology, 2022 Biological dinitrogen (N2) fixation is performed solely by specialized bacteria and archaea termed diazotrophs, introducing new reactive nitrogen into aquatic environments.

Bacterial Life and Dinitrogen Fixation at a Gypsum Rock [PDF]
Applied and Environmental Microbiology, 2004 ABSTRACT The organisms of a bluish-green layer beneath the shards of a gypsum rock were characterized by molecular techniques. The cyanobacterial consortium consisted almost exclusively of Chroococcidiopsis spp. The organisms of the shards expressed nitrogenase activity (C 2 H

Preliminary estimates of the contribution of Arctic nitrogen fixation to the global nitrogen budget
Limnology and Oceanography Letters, 2017 Dinitrogen (N2) fixation is the source of all biologically available nitrogen on earth, and its presence or absence impacts net primary production and global biogeochemical cycles.
